weight 64kDa. Keywords: Phytase‚ Aspergillus fumigatus and Aspergillus terreus. INTRODUCTION Phytase is widespread in nature‚ occurring in plants‚ microorganisms‚ as well as in some animals. Microbial Phytase activity was most frequently detected in fungi. Phytic acid was discovered as early as in 1872 by Pfeffer and a first note on Phytase can be found in the literature in 1907. Phytase belongs to the group of phosphoric monoester hydrolases; it catalyzes the hydrolysis of myo-inositol hexakisphosphate

chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto them. To overcome this‚ the biological method provides a feasible alternative. The major biological systems involved in this are bacteria‚ fungi‚ and plant extracts.

In this essay‚ I will analyze how the state of the house‚ the eye-like windows‚ the collapse of the house‚ the presence

The catabolism (breakdown of molecules into smaller units) of the organic compounds is mostly accomplished by bacteria and fungi. However if one considers decomposition as the disappearance or breakdown of organic litter then the soil fauna (invertebrates such as the springtails‚ mites‚ isopods‚ etc) must be included in this array of soil biota that contributes to the decomposition

Laboratory Science Abstract 85% of all medical decisions are based on the results of clinical laboratory testing. Medical laboratory science is the use of clinical laboratory tests to detect‚ diagnose‚ monitor and treat disease. Blood‚ tissue and body fluid can be chemically analyzed and examined for foreign organisms and abnormalities. This information is then used by the medical team to make decisions regarding medical care. Laboratory scientists have made important contributions to the development

from infectious diseases. Today‚ none of us can imagine living in a world without antimicrobials. What is antimicrobial resistance? Antimicrobial resistance – also known as drug resistance – occurs when microorganisms such as bacteria‚ viruses‚ fungi and parasites change in ways that render the medications used to cure the infections they cause ineffective. When the microorganisms become resistant to most antimicrobials they are often referred to as “superbugs”. This is a major concern because

Coprinus: It is a small genus of mushrooms that decomposes organic matter in nature. They belong to the kingdom fungi. Coprinus can grow alone or in clusters‚ lines‚ or fairy rings on lawns‚ wood chips‚ or hard-packed ground. The common fungus is coprinus comatus.
