Statistical optimization of medium components for chromate reduction by halophilic Streptomyces sp. MS-2

Extensive use of hexavalent chromium Cr(VI) in various industrial applications has caused substantial environmental contamination. A marine bacterium,Streptomyces sp. MS-2 showed a high Cr(VI) reduction performance.Streptomyces sp. MS-2 completely reduced 75 mg/l Cr(VI) within 72 h of growth. The effectiveness of the bacterium for reducing Cr(VI) under different conditions was evaluated. Optimum pH and...

Ethanol production from the water hyacinth Eichhornia crassipes by yeast isolated from various hydrospheres

Water hyacinth is a promising plant for the production of bioethanol. The water hyacinth was saccharified with diluted sulfuric acid and fermented to ethanol by yeast obtained from different hydrospheres. We found that the best conditions for water hyacinth hydrolysis were 1% (v/v) sulfuric acid at 121oC for 1 h. In the next step, we searched for yeast that could produce ethanol from the water hyacinth hydrolysate. For...

Immune response and protection of free range chickens vaccinated orally with feeding of Newcastle disease vaccine-coated cassava granules

Cassava granules coated with Newcastle disease virus (NDV) strain V4-UPM was used to vaccinate free-range chickens in their natural habitat. Immune response, vaccine virus excretion and the efficacy of the food vaccine were assessed by standard methods. Results show that out of 218 chickens given initial food vaccine in the four locations, 138 (63.3%) produced detectable HI antibody while 202 (92.7%) had titres <...

In vitro anti-bacterial activity of a novel isoquinoline derivative and its post antibacterial effects on Pseudomonas aeruginosa

The isoquinolines are of great importance to humanity because of their medicinal value and different structure. There have been many researches on the isoquinolines, but relatively few pure compounds have been investigated for their antibacterial activity. The in vitro activity of a novel synthetic antimicrobial compound1-(4-choloro-phenyl)-6,7-dimethoxy-2-methyl-1,2,3,4, tetrahydroisoquinoline was evaluated...

Microbiological quality of water, associated management practices and risks at source, transport and storage points in a rural community of Lungwena, Malawi

This study investigated and compared the microbiological quality of source, transported and stored water in Lungwena households. It also examined water management practices at all the investigated points. One hundred and eighty (180) water samples were collected from 6 villages and tested for Escherichia coli, Salmonella, E .coli 0157:H7 and Campylobacter jejuni using standard methods....
