Techniques are presented to develop spectroscopic factors directly from circular dichroism spectra of proteins using singular value decomposition on a small database. Four spectra of maximum spectral variability are chosen to characterize the database. These selected protein spectra are then factored by singular values into component spectra, which are collected as comparative vector characteristics used as factor fractions. The necessary standardization for comparison is achieved using unit nor...

In order to obtain the optimal conditions for the degradation of phenol by Pseudomonas stutzeri ZH-1, based on the single factor experiment, the Box Behnken design test of Response Surface Method was used. Four variables of glucose concentration (0.4, 0.6, 0.8 g/L), inoculation concentration (3%, 5%, 7%), pH (6, 7, 8) and temperature (35°C, 37.5°C, 40°C) were used to identify the significant effects and interactions in the batch studies. A second order polynomial regression mo...

There is always the need to study the bioactive components present in the various parts of edible fruits. This will go a long way to providing an idea of its potential biological benefits when consumed. The current study evaluated the protective effect of C. lanatus fruit’s endocarp/exocarp, mesocarp and seed extracts on the liver of albino rats. The qualitative and quantitative phytochemical analysis was also done following standard methods. The albino rats were divided into nine groups of five...

Wheat straw is an ideal green renewable resource, which is widely used as fertilizers, feedstuffs, edible funguses, industrial raw materials and fuels. Hydrothermal liquefaction of biomass that works under normal or slightly pressurized conditions results in higher oil quality. We summarize the technical principles of hydrothermal liquefaction, analyze the difficulties and problems in the utilization of various technologies, and put forward the development trend of promoting the application of b...

Photosynthetic bacteria (PSB) wastewater treatment is a new method with great resource recovery potential. In order to improve the biomass and valuable resources of bacteria in the wastewater treatment of photosynthetic bacteria, the effects of different light conditions on the efficiency of Proteiniphilum acetatigenes PSB-W in the treatment of sugar wastewater and the production of bacteria and carotenoids in the wastewater were analyzed from three aspects of light source, light intensity and l...

Background: Recently epidemiological studies have shown that type 2 diabetes mellitus is great a risk factor for cardiovascular mortality. Electrolyte abnormalities are commonly encountered in chronic diabetes mellitus type 2 patients. Aim: The aim of this study was to estimate serum electrolyte levels & HbA1C levels among Sudanese diabetic Patients with macrovascular complications in Khartoum State, Sudan. Materials & Methods: In this case, control hospital based study conducted in Khartoum sta...

Hydrogen peroxide (H2O2) is a signal molecule that plays a crucial role in plant secondary metabolism. In order to explore the signaling mechanism of endophytic fungal elicitors (Penicillium commune 2J1) for promoting 1,8-eucalyptus accumulation in C. longepaniculatum, changes in the contents of H2O2 and 1,8-eucalyptus were investigated after the addition of elicitors to the C. longepaniculatum cultures. The experimental results s ...

Salicylic acid (SA) and hydrogen peroxide (H2O2) are signal molecule that plays crucial roles in plant secondary metabolism. In order to explore their roles in mediating the effect of endophytic fungal elicitors on essential oils in the suspension cells of Cinnamomum longepaniculatum fungus, an elicitor made of Penicillium sp. was used as material in this experiment. Cell suspension culture was used to study the effects of SA and ...

Mushrooms are fungi that are unique in the recycling of plant biomass through decomposition in the process of which they also serve as food for man. These functions are carried out through the extracellular digestion of plant biomass with a consortium of enzymes. This study examined the effect of carbon-nitrogen ratios (C/N) of three lignocellulosic substrates, namely, corncob (C/N 120:1), sawdust (C/N 325:1) and waste paper (C/N ...
