Abstract: Micrococcus luteus synthesises glucose and protein during the fermentation of a Nigerian rice. To regulate the formation of these substances, mutation was carried out with an alkylating agent: ethylmethyl sulphonate (EMS). Screening the mutants generated for the levels of the traits expressed, four major groups were obtained. These are poor, moderate, good and super producers of either glucose or protein. They produced the properties at 0 - 1.00, 1.01 to 1.99 (moderate) and 2.0 to 2.99 (good) and 3.0 and above (super) mg.mL–1 of each substance. The classes were made up of 37, 40, 20 and 3 mutants for glucose production and 13, 35, 40 and 12 mutants for protein synthesis. The wild strain bacterium made 0.86 mg.mL–1 glucose and 1.2 mg.mL–1 protein describing the M. luteus as poor glucose maker and moderate protein producer. It was also noticed that the mutation caused some variants (25%) to form more glucose than protein; the remaining 75% of the population are made up of two sets viz: mutants having better ability to synthesise protein at higher concentrations than glucose and those that formed about the same amounts of the substances. It thus follows that the glucose and protein productions in M. luteus are genetically based and can be regulated by genetic manipulation.

Abstract: This work aimed at the control of the production of protein and glucose-anabolic-enzyme (GAE) by Saccharomyces cerevisiae during the fermentation of a Nigerian rice, Oryza sativa variety “Igbimo”. The yeast was mutated with ethylmethyl sulphonate. The variants and the parental yeast were separately inoculated into cooked rice and allowed to ferment at 27℃ for 7 days after which protein content and glucose-anabolic-enzyme synthesis were determined using Dinitrosalicylic acid and Biuret reagents techniques. Mutants with varying capacities to form protein and GAE were obtained. Glucose-Anabolic-Enzyme (GAE) activity ranged from 0.25 to 12.06 Units forming five groups (classes 1, 2, 3, 4 and 5) with the average activity of 0.52, 1.52, 2.28, 4.04 and 10.63 Units respectively compared with that (0.38 Unit) of the parent strain. All the mutants synthesized protein although many of them produced it at lower level while others at higher level than the wild-type. The highest (5.92 mg/mL) and lowest (0.10 mg/mL) levels protein producers are mutants 44 and 14 respectively. Mutants No. 4, 7, 22 and 78 formed total protein similar in concentrations (1.46, 1.46, 1.45 and 1.45 mg/mL) to that of the wild yeast (1.46 mg/mL). These three sets of protein concentration have ratios 4.1 (highest), 0.07 (lowest) and 1.0 (normal) to that of the parental yeast.

Advances in Microbiology (AiM) , 2015, DOI: 10.4236/aim.2015.54024
Abstract: Microorganisms (bacteria and fungi) were isolated from different parts of yellow maize (stem, cob, husk, leaf, root) as well as from rhizosphere and non-rhizosphere soil of maize using conventional microbiological techniques. A total number of twenty-six bacteria and thirteen fungi were isolated. The antagonistic efficacies of these isolates were tested against Sclerotium rolfsii, Aspergillus repens, Penicillium notatum and Pythium sp. using streak bioassay, food poisoning and dual culture techniques. None of the bacteria was antagonistic to the test fungi at 25°C on PDA using streak bioassay. However, there was reduction in the population density of the test fungi using food poisoning technique. The fungal isolates were antagonistic to the test fungi in varying degrees. Generally, S. rolfsii was susceptible to seven out of the eight fungal antagonists while P. notatum was least susceptible. The percentage reduction of S. rolfsii ranged from 40.00 ± 5.78 to 64.07 ± 2.31. Efficacies of chemical fungicides; mancozeb, camazeb and red force at 3 different concentrations— 0.05%, 0.1% and 1.0% (w/v) on the test fungi were also determined. No growth of the test fungi was observed at 1% (w/v) of all the fungicides while at lower concentration (0.05%), red force did not have any inhibitory effect. The growth of S. rolfsii was completely inhibited at 0.05% of mancozeb whereas there was reduction in mycelial growth of A. repens. Effect of inoculation time and nutrients (PDA and MEA) was determined on the antagonistic activities of Trichoderma viride. There were significant differences in inhibitory potentials of the two isolates of Trichoderma viride when pre-inoculated on the culture medium. The antagonistic potentials were more pronounced on malt extract agar than potato dextrose agar.

Abstract: This study focused on the development of thermophilic strain/s of a cowpea (Vigna unguiculata) compatible nitrogen fixing bacterium. A preliminary plant screening was carried out using some strains of tropical rhizobia and cowpea. Rhizobium species CWP G34A that formed Fix+ nodules repeatedly was selected for further studies. First, it was tested for growth at high temperatures of 40 to 55oC at 5oC interval with 28oC as the control temperature. Mutagenesis was conducted on the bacterium with ethylmethane sulphonate (EMS). The wildtype and mutants generated were tested for high temperature tolerance by growing them individually in nutrient broth at 60oC for 24 hours. Optical density (670 nm) was read before and after incubation. The mutants were grouped into classes based on percentage difference in OD values obtained before and after exposure to 60oC. Rhizobium species CWP G34A produced functional pink nodules on the cowpea consistently in three different plant tests. There was no growth at all the temperatures tested except at 28oC and 40oC after 24 hours of incubation. It grew better at former (51 × 1010 Cfu/ml) than latter (11 Cfu/ml) temperature. Like the parental strain, all the mutants but one, did not grow after exposure to 60oC. Sixty degree centigrade caused various reductions in optical density (OD) values of the variants. Eleven classes of the mutants were formed with membership percentage ranging from 1 to 22%. Class 1 contains only one member while class 11 has the highest mutant population of 22% with OD difference of 0 to 10% and –90 to –100% respectively. The high percentage reduction in the OD of variants in class 11 is similar to that of the unmutated cells (–94.56%). The only mutant that survived the 60oC and grew was MU70. An increase of 1.67% in OD was obtained for MU70. Mutant MU70 therefore appeared a promising strain that can be further tested to inoculate cowpea in the dry and warm season for increased nitrogen fixation. This will provide encouraging information for farmers to grow the cowpea throughout the year particularly under high temperatures in summer in order to boost the yield of the legume.

Journal of Microbiology, Biotechnology and Food Sciences , 2012,
Abstract: To evaluate the health relevance of decoctions, infusions and concoction of medicinal plants in traditional medicine, antibacterial efficacy of crude aqueous, ethanol and petroleum ether extracts of Cnestis ferruginea leaf, stem bark and roots were assayed against nine clinical bacterial isolates namely Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus cereus, Shigalla dysenteriae, Campylobacter jejunum, a -hemolytic group A streptococcus, and Salmonella enterica ser.Typhi by agar well diffusion method. The leaf extracts had higher inhibitory effects at various degrees than the stem bark and root extracts. Chemical methods were used to determine the quality and quantity of phytochemical components where alkaloids, flavonoids, saponin, tannins, phenol and cardinolides were found present. The antioxidant activities of the extracts of the plant tested were determined by a spectrophotometric method using the stable free radical DPPH (2, 2-diphenyl-1-picrylhydrazyl). Considerable antioxidant activities were found in the plant extracts. C. ferruginea contains bioactive principles necessary for bacteria inhibition and therefore, the powder could be used as preservative, beverage and source of novel drug(s).
Autonomy and interdependence: quandaries in research ethics  [PDF]
Bolatito Lanre-Abass
Health (Health) , 2012, DOI: 10.4236/health.2012.44026
Abstract: The autonomy of research participants is crucial in research ethics without which it will be difficult to carry out research. Central to the concept of autonomy is the debate on whether the cultural norms of individuals (particularly women) should be given priority in settings where these norms require that researchers should go through male heads such as husbands and traditional leaders. This paper examines issues relating to the autonomy of women in research ethics. It highlights the far-reaching implications of autonomy for women participating in research using Islam as a religion and Africa as case studies. The paper takes a look at what obtains in Ghana and Nigeria as African countries with diverse religious sects highlighting at the same time the extent to which women are autonomous in some Islamic parts of India and Pakistan. The paper stresses that in spite of certain factors limiting the autonomy of women in Africa and Islam, there is need for a more robust account of autonomy. It takes a relational approach to autonomy concluding at the same time that the best way to do bioethics is to be culture-sensitive.
Palaeoclimatic Evidences from the Quaternary Coastal Deposits, Southwestern, Nigeria  [PDF]
Olugbenga A. Boboye, Adewale Akinmosin
Open Journal of Geology (OJG) , 2018, DOI: 10.4236/ojg.2018.86034
Abstract: The studies on some samples retrieved from the coastal sediment deposit have been carried out. The palynological and geochemical indices were evaluated with the view of determining their chronology, palaeoclimatic conditions that prevailed during the time of their emplacement and also to re-asses the palaeoenvironment of the Lagos coastal deposit in Dahomey Basin. The identification of diagnostic species age entails the palynological analysis while the geochemical analysis determines the provenance of these Quaternary sediments. The occurrences of Laevigatosporites sp., Zonocostites ramonae, Acrostichum aureum in abundance along with few long ranging forms suggest that the vegetation development was under a humid climate and that the sediments were deposited during cooler and wetter conditions. The presence and high abundance of Crassoretitriletes vanraadshooveni, Zonocostites ramonae, Canthiumidites sp., Sapotaceoidaepollenites sp. and Pachydermitesdiederixi palynomorphs indicate an age range of late Pliocene (Gelasian) to early Pleistocene (Calabrian) (2.588 - 1.806 Ma). This age range is known to correspond to the 3.7 - 3.8 depositional cycles of relative change of coastal On-lap. The geochemical appraisal showed that the ratios of organic carbon-nitrogen (C/N) indicate that the sediments were sourced from aquatic, protein-rich and cellulose-poor milieu. The wetter climatic period has enhanced algae productivity as a consequence of greater wash-in of soil nutrients, and these periods are recorded as increased rate of organic carbon mass accumulation. Conversely, the dominance of a mangrove habitat, Zonocostites ramonae suggests a mangrove swamp environment which was the most prevalent environment of the Lagos lagoon in the Pleistocene.

Abstract:

The detail mapping and logging of the Ibese area within the Dahomey Basin has revealed the total thickness of the limestone to range between 12.0 m to 15.0 m. This study is based on qualitative lithologic, spectrochemical analyses via X-ray fluorescence and petrographic indices to understand the lithofacie, chemistry, viability of the sequences and depositional environment. This consists of milky to grey and nodular to massive fossiliferous limestone units while the sand content increases with depth. The composition of the major oxides in the thirty-seven (37) samples from six exploratory wells revealed that CaO (51% - 56%), SiO2 (2.6% - 10.56%), Fe2O3 (0.33% - 0.94%), MgO (0.78% - 1.02% and Al2O3 (0.72% - 0.98%) were the most abundant elements. The trend of the geochemical indices show increase in the percentage composition of CaO, and MgO down the sequences with high values which defined the depth of diagenetic re-distribution. The percentage composition of Al2O3, Fe2O3 and K2O are significant indicating continental influence during diagenesis and diverse depositional episodes. The three different microfacies recognized based on depositional texture are shelly biomicrite, shelly biosparmicrite and alga biosparmicrite. The predominance of micrite as the cementing matrix revealed that the rock was deposited in a quiet shallow inner shelf environment occasioned by storm waves.

The Natural Law Theory of Morality and the Homosexuality Debate in an African Culture
L-A Bolatito
OGIRISI: a New Journal of African Studies , 2012,
Abstract: Same sex relationship has recently been criticized by many not only on grounds of being immoral but also as a practice that erodes certain values attached to marriage and procreation in some African cultures. This paper examines the immorality or otherwise of homosexuality as an act. It argues that homosexual behaviour is degrading and damaging as an act because it devalues the institution of marriage and its related values in the Yoruba culture. The paper underscores the fact that a typical Yoruba would make allusions to either Christian or Islamic injunctions to justify the moral unacceptability of homosexuality as an act. It employs Aquinas natural law theory of morality to further argue that homosexual act is unnatural hence it goes against what reason dictates. The paper also argues that we cannot completely rule out the possibility that homosexual acts are consequences of certain predisposing biological factors over which actors have no control and if this is the case, then they cannot act otherwise. In the light of this, the paper argued for both nature and nurture as predisposing factors of homosexual behavior. It concludes by stressing that in spite of some biological arguments in favour of homosexual act, such act threatens the viability of the Yoruba community where special value is placed on the institution of marriage and procreation.
Modernism and Secularization: Towards a Reconciliation of Religious Freedom and National Security in the Realization of Peace in Nigeria
Lanre Abass Bolatito
Canadian Social Science , 2013, DOI: 10.3968/3281
Abstract: This paper examines religious violence in some Northern parts of Nigeria and its effects on national security. It argues that Modern religiously motivated violence has affected the balance between individual religious liberty and national security in this country. The paper attributes this to modernism and its feature of secularization particularly as it displaces some religious values such as love, peace, concern for others, the fear of God and so on. The paper underscores the need for peace in Nigeria and for government to address the conflicting duties of allowing people to exercise their religious freedom and maintaining national security. It draws on W.D Ross’s prima facie and actual duties to argue that when duties conflict, there is need to arrive at a substantive duty after a fully considered deliberation. Unfortunately, one cannot be allowed without it having a negative effect on the other. In order to avoid a situation whereby attempts at resolving conflicting duties on the part of government degenerates into a more intense violent conflict, there is need to reconcile religious freedom and national security. The paper concludes by stressing that since religious freedom and national security are crucial elements in the functioning of the society, there is need for Nigerian government to reconcile both without one necessarily affecting the other in a negative sense; this will give room for peaceful co-existence in this country. Key words: Violence; Peace; Security; Secularization; Modernism; Religion
