Sargassum, Gracilaria and Ulva Exhibit Positive Antimicrobial Activity against Human Pathogens

Amrit Kumar Mishra
Bacterial resistance to pharmaceutical drugs is on rise, which emphasizes the need for screening of new drugs from natural resources. Seaweeds from the marine ecosystem are important source of bioactive compounds making them one of the major subjects for screening of various pharmaceutical drugs. So here, we assessed the bacterial growth inhibitory functions of four seaweeds Sargassum wightii

Antimicrobial Activity, Cytotoxicity and Phytochemical Analysis of Sanguinaria canadensis Native to South Dakota

Gitanjali NandaKafle, R. Neil Reese, Robert Oda
A methanolic extract of Sanguinaria canadensis rhizome contains a mixture of benzophenanthridine alkaloids with the major component sanguinarine. American Indians used this rhizome in the treatment of rheumatism, asthma, bronchitis, lung ailments, fever, and warts. Lethal diarrhea in neonatal and post-weaned pigs due to enterotoxigenic Escherchia coli (ETEC) is a major problem among the swine producers of South Dakota region. The increasing resistance of ETEC towards synthetic antibiotics is a m...

The Effect of Different Wavelength of Light for Microbial Fuel Cell with an Anode of Rhodopseudomonas faecalis (PSB-B)

Guang Rong, Qingping Hu
A microbial fuel cell (MFC) with an algae-assisted cathode is a low-cost and sustainable way to provide the oxygen for the oxygen reduction reaction. The anode was with anaerobic microorganism, a kind of photosynthetic bacteria (PSB-B). An algae bioreactor was connected to cathode microbial fuel cells to increase power generation by supplying more oxygen to cathode electrode. In this study, we

Report of Mollicutes in the Ear Canal of Domestic Dogs in Brazil

Sandra Batista dos Santos, Maina de Souza Almeida, Luana Thamires Raposo da Silva, Junior Mario Baltazar de Oliveira, Carlos Adriano de Santana Leal, Jose Wilton Pinheiro Junior, Rinaldo Aparecido Mota
Several microorganisms as bacteria, fungi, yeast and ectoparasites compose canine ear canal microbiota. These agents can be native or invasive pathogens that cause clinical otitis. The aim of this study was to associate Mollicutes in external ear canal with clinical otitis. 41 domestic dogs were examined, and a total of 82 otologic samples were collected using sterile swabs, placed in a plastic storage tube containing 2 milliliter

Comparative Study of Two Conventional Methods Used for Coliform Enumeration from Port Harcourt Waters

Prince Chinonso Nnadozie
This study compares two conventional methods: Membrane Filtration (MF) and Multiple Tube Fermentation (MTF) used in the analysis of two Port Harcourt natural water sources, Abonnema Wharf (A) and Tourist Beach (B). However, these methods are generally used in the determination of the sanitary condition of the waters and its suitability for general use. It is observed from the study that the MF gives a more reliable and precised data than that of the MTF which is time consuming, labour intensive ...

A Voyage to Beyond the Human Eye by Microscope, Leeuwenheok's Invention

Nasser Pouyan
Microscope, an instrument used for obtaining magnified image of small objects. The term of microscope was coined by Johannes Faber of Bamberg. The identity of its inventor has not been clearly established. Aristotle about 24 centuries before Leeuwenhoek described the working of microscope in some detail. The earliest records of optical lenses date from the late 13th century, when spectacles came into use. Roger Bacon, in his “Opus Magnus” of 1268 spoke of the use of lenses for magnify...

Petroleum: From Basic Features to Hydrocarbons Bioremediation in Oceans

Edmo M. Rodrigues, Marcos R. Tótola
This review provides a general overview of petroleum characteristics and bioremediation strategies applications in oceanic environments contaminated with petroleum hydrocarbons during exploration and transportation processes offshore. The vast oil reserves in the offshore fields have been explored for the production of light and heavy oil. The hydrocarbons exhibit very different physicochemical characteristics including those of hydrophobicity, molecular weight, melting and boiling points, toxic...
