Amylase Production by Solid State Fermentation of Corn (Zea Mays) Stem Using Fusarium and Mucor

Abstract The study aimed at producing amylase from corn stem using Mucor and Fusarium in solid state fermentation. The Fungi used in this study were isolated from the rhizosphere of the corn plant. Solid state technique was adopted for the fermentation process using spore suspension as inoculum. Various fermentation parameters such as  incubation days, addition of salt supplement, substrate concentration, mycelia suspension and temperature were optimized during fermentation with the...

Hepatitis B

Hepatitis B is an infection of your liver. It can cause scarring of the organ, liver failure, and cancer. It can be fatal if it isn’t treated.It’s spread when people come in contact with the blood, open sores, or body fluids of someone who has the hepatitis B virus. The disease don’t last a long time. Your body fights it off within a few months, and you’re immune for the rest of your life.Hepatitis B is a contagious liver infsection caused by the hepatitis B virus (HBV).  ...

Evaluation of Inhibitory Zone Diameter (IZD) of crude Spondias mombin (Linn.) extracts (root, leaf, and stem bark) against thirty infectious clinical and environmental isolates.

AbstractThe purpose of this work is to evaluate the Inhibitory Zone Diameter (IZD) of crude Spondias mombin extracts against thirty infectious clinical and environmental organisms. The root, leaf and stem-bark of S. mombin were harvested and air-dried. The dried S. mombin was milled into powdered form using manual grinder. Powdered S. mombin (1kg) each of the different S. mombin parts was extracted with 3 L of 70% (v/v) ethanol, ethyl acetate and distilled water for 72 h at room temperature....

Evaluation of antimicrobial activities of crude ethyl

The purpose of this research work is to determine the antimicrobial activities of crude ethyl acetate and ethanolic extracts of Morinda lucida leaf, stem, and bark growing in Adekunle Ajasin University Botanical Garden against selected clinical isolates. The plant Morindal lucida falls under the family Rubiaceae known to have wide usage in traditional medicine. Morinda lucida is a tropical West African tree of medium-size about 18–25 m tall, the bark is grey to brown in color, flowers are w...

PREVALENCE OF UROPATHOGENIC ESCHERICHIA COLI & STAPHYLOCOCCUS AUREUS AMONG PATIENTS WITH CASES OF URINARY TRACT INFECTIONS ATTENDING BENUE STATE UNIVERSITY TEACHING HOSPITAL, MAKURDI

ABSTRACT In the present study, we investigated the prevalence of few bacterial organisms associated with urinary tracts infection and their antimicrobial susceptibility patterns. Total of Ninety (90) midstream urine samples were collected from outpatients with respect to their age group, gender and marital status attending health facility in Benue State University Teaching Hospital Makurdi. Each 0.1ml of urine sample was cultured on MacConkey agar and colonies showing lactose fermentation wer...

Production of protease enzyme from fish guts using Pseudomonas fluorescens, Enterobacter cloacae and Bacillus megaterium.

Food industry wastes are an essential environmental contamination source. A large number of microorganisms including bacteria, yeast and fungi produce different types of enzymes like protease, lipase, chitinase, chitosan and ligninolytic enzyme having high biotechnological interest such as food processing, detergent, textile, pharmaceutical products, and medical therapy. Microbial synthesis of enzymes has been reported to be influenced by various factors such as carbon sources, nitrogen sourc...

Multidrug Resistant Salmonella enterica Strains in South Western Nigeria: Prevalence and Susceptibility to Ceftriaxone

Aims: To investigate the prevalence and susceptibility pattern Salmonella enterica strains to ceftriaxone in southwestern Nigeria. Place and Duration of Study: Faculty of Pharmacy, University of Ibadan, Nigeria from November 2012-May 2013. Methodology: Isolates of Salmonella enterica were characterized by established standard cultural and biochemical tests and was screened in-vitro for their sensitivity to different antibiotics (ampicillin, amoxicillin, chloramphenicol, cotrimoxazole and ceft...

Microbiology of meat spoilage - Dandy Etim Okon

This paper is titled 'Microbiology of Meat Spoilage'. It clearly explains those Spoilage microorganisms associated with the Spoilage of meat and meat products and also the preservative method to be used in preserving meat.On the basis of its high moisture content and presence of adequate nutrient, meat is regarded   as   the   most   perishable   product   (Magnus,   1986)   and   thereby   hig...

Effect of processing on micronutrients (calcium, iron, vitamin A, and zinc) in maize, bambara groundnut, cowpea, cattle bone, roselle calyces, palm oil, Brachystegia eurycoma and Althernanthe

Norovirus

NOROVIRUSNorovirus (NoV), causing the winter vomiting disease, is today recognized as the most important agent of acute human gastroenteritisThe etiology of diarrheas can involve several agents, such as viruses, bacteria, and parasites. Bacterial agents are relatively more important in developing countries, whereas viral agents are more relevant in industrialized countries. The importance of these agents is related to hygiene and sanitation conditions for the population1. In 1972, a 27-nm vir...
