Psychrophilic enzymes are biocatalysts that control biochemical processes at low temperatures by either accelerating or decreasing the reaction rate. These enzymes are mainly obtained from microorganisms which inhabit cold environments and proliferate at low temperatures. The cold-loving organisms referred to as psychrophiles are adapted to the extreme cold conditions which resulted in changes in their biochemical machineries such as their enzymes. This resulted in certain characteristics of ...
Abstract Forensic Mycology is the application of Mycology for producing evidence in terms of criminal investigation and their further evaluation in the court of law. The problem with relative neglect of Mycology in Forensic science is currently leading to insufficient knowledge, in order to support the needs for fungal expertise in areas of criminal investigation. Mucor hiemalis and Penicillium griseofulvum had been used to determine the minimum interval since death, Coprinus comatus, Hebelom...
Summary So far, majority of the preventive effect of prebiotics has been on animal models. However, several in vitro studies using 2D and 3D cell cultures mimicking the environmental condition as well as various organisms present within the gut of man had shown the efficacy of prebiotics in reducing the attachment of enteropathogenic organisms like S. typhi to the gut epithelium. In vivo studies with human have been able to prove its efficacy in preventing diseases such as Inflammatory bowel ...
Mushroom is a macro fungus with a distinctive fruiting body which can be either epigeous or hypogeous and large enough to be seen with the naked eye and can be picked with hand (Chang and Milles.19920). Mushrooms derive all of their energy and growth materials from their growth medium, through biochemical decomposition processes (Chang, Shu-Ting, et al. 2004).
ABSTRACT Bio-fuels are prominent in current discussions both as a solution to problems and as a creator of problems. They have promise as a substitute for fossil fuels, particularly petroleum as the raw material for transportation fuel. But bio-fuels also have pitfalls, especially when produced at a scale sufficient to replace a significant proportion of the world's use of petroleum. This controversial topic has attracted great political, economic and social attention because of its touching...
A human or animal with an infection has another organism inside them which gets its sustenance (nourishment) from that person, it colonizes that person and reproduces inside them. The human with that organism (germ) inside is called the host, while the germ or pathogen is referred to as a parasitic organism. Another name for an organism that causes infection is an infectious agent. It is only an infection if the colonization harms the host i.e parasitic relationship. It feeds and multiply ...
INTRODUCTION Cholera is an acute bacterial infection of the intestine caused by ingestion of food or water containing Vibrio cholerae, serogroups O139, it is a disease characterized by profuse diarrhea accompanied with a severe dehydration and loss of electrolyte (Colwell and Huq, 1994), caused by toxigenic Vibrio cholerae, a serologically diverse, environmental, and gram-negative rod bacterium (Li et al.,2002). In the absence of appropriate treatment, there is a high mortality rate. Cho...
INTRODUCTION In the production of food, it is crucial to take proper measures to ensure its safety and stability during the shelf-life. At present, many food industries are faced with different microbiological problems such as emergence of new pathogens and pathogens not previously associated withfood consumption, as well as the ability of microorganism to adapt and its resultant mutation that has given rise to altered food safety (Galvez et al., 2007). The empirical use of microorganism...
1.0 INTRODUCTION Back in 1928, Alexander Fleming began the microbial drug era when he discovered in a Petri dish seeded with Staphylococcus aureus that a compound produced by a mold killed the bacteria. The mold, identified as Penicillium notatum, produced an active agent that was named penicillin. Later, penicillin was isolated as a yellow powder and used as a potent antibacterial compound during World War II. By using Fleming’s method, other naturally occurring substances, such as chl...
