Microorganism or microbe is an organism that is microscopic (Jain, 2010). The study of microorganisms is called microbiology. Microorganism include bacteria, fungi, archae or protists but not strictly viruses and prions, which are generally classified as non-living. Most microorganism are single celled, or unicellular, but some are microscopic and some unicellular protists are visible to the average human. Microorganisms are ubiquitous and live in most inhospitable sites across the various ecosystems
lacquer (hence the name "laccase"). Laccase enzymes belong to the group of diphenol oxidase family (E.C. 1.10.3.2.) acts on phenolic and non phenolic substrates due to wide substrate specificity. Laccases are widely distributed among plants, fungi, bacteria and insects. Rhus vernicifera, well studied plant source for laccase, cell culture of Acer pseudoplatanus, xylum tissue of Pinus taeda and Populus euramericana, green shoots of tea and leaves of Aesculus parviflora, cabbage, turnips, apples, beets
were then used on the unknown to help identify further characteristics of the bacterium. Data was collected and assessed to determine the particular unknown. Introduction Earth came into existence 4.6 billion years ago, but the first form of life did not appear until 3.5 Billion years ago (1). These cells were known as prokaryotes. Prokaryotes
Till now, there remains limited information about the link between microbial community composition and functioning in aquatic ecosystems. Microorganisms are to be counted among the essential components of virtually all ecosystems. Heterotrophic microorganisms have their place among the decomposers, mineralizers as
Methods used in plant microbiology Plant pathology is the study of plant diseases caused by pathogens and environmental conditions. Food loses due to infection caused by microorganisms like bacteria, fungi, viruses, protozoa etc has become one of the unrelenting effects. Basic culture methods Plate Procedure In this process, the number of microbes present in a mixed sample are calculated and then add this sample on an agar medium and allow it to solidify. Dilute the samples and pour it on
1.0 INTRODUCTION 1.1 Background of Study Environment pollution is one of the major problem that faced by many country in this world. Pollution is defined as undesirable change in the physical, chemical and biological characteristics of all components of an environment (Fatuyi et.al.,2011; Aboriba, 2001). One of the problems is the oil spillage pollution. Environment pollution due to oil spill is one of the frequent problem happened in country that has petroleum source like Malaysia, Nigeria
pH were the conditions tested. The characteristics that were studied using the five conditions were the growth of S. marcescens in relation to prodigiosin production over a period of three hours. Senaite Tewolde-Mesfin Professor Eaton BIO 101-Lab 24 October 2014 Abstract: In this experiment, S. marcescens was the organism we worked with. As S. marcescens grows, it produces a red-pigmented secretion called prodigiosin. Its gram-negative characteristic makes it easier to spot prodigiosin
sloths are known by every person who has seen them move extremely slow. Actually, there are so many kinds of sloth but they can all fall into two categories: Three-toed sloths and two-toed sloths. There is a main standard can be used to distinguish between them. It is not difficult for others to see the differences because one has two toes on its forelimbs and the other has three. Except that two-toed is little bigger than three-toed sloth. However, it is so ambiguous to distinguish them for obvious
This is not necessarily beneficial or detrimental to the overall fitness of the species; organisms with favorable characteristics are better able to pass their traits than unfit organisms, and frequency of traits in the population will tend to shift towards advantageous genes, provided the environment is selective. The mechanism of natural selection is able to take place
