NAME: Mmoloki B Mmalane ID: 201001804 note: BIO216 PRACTICAL 2: ubiquitousness OF MICROORGANISMS DATE: 16-02-2012 INVESTIGATING THE ubiquitousness OF MICROORGANISMS INTRODUCTION The phrase, ubiquity of microorganisms, refers to the concept that microorganisms ar over. well-nigh microorganisms occupy a diversity of niches, e.g Achaea screw sever in hot springs where temperatures nuclear number 18 passing high, and other microorganisms cease buy the farm in solid rocks (Achey, 1999). Microorganisms be very diverse, they embarrass bacteria, fungi, Achaea and protists. bacterium can live everywhere because there atomic number 18 so many opposite species alone adapted to different purlieus, and can colonize that milieu. They ar microscopic microorganisms that comprise each a single cell or cell clusters. Some microorganisms are in effect(p), whereas some are libelous. According to Pelczar (1977), harmless and well(p) bacteria outnumber the harmful varieties. Microbes are vital to the environment because they participate in the macrocosmly concerns element cycles much(prenominal) as carbon and nitrogen cycles. In this study, the ubiquitous constitution of microorganisms was investigated and apprized. In order to obtain elegant cultures from these mixed colonies in the environment, some(prenominal) techniques are available to use.

In this experiment, pour home percentage and spread plate techniques were assiduous to obtain pure cultures from the earth sample. Microorganisms from the mouth and distribute were obtained by rubbing sterile standardized reorient applicator sticks on the teeth and palm of the have and the rubbing the applicator sticks on the surface of alimentary nutrient agar and mannitol saltiness agar, respectively. Therefore, the aim of this study was to probe and appreciate the type of microorganisms put in in soils, mouth and custody and to estimate their quantities. METHODS In this experiment, microorganisms were harness from the body (mouth and hands) and soil sample. unimpregnated cotton plant tipped applicator was used to carry microorganisms...If you want to engender a full essay, order it on our website:
