Ubiquity Of Microorganisms

NAME: Mmoloki B Mmalane ID: 201001804 argument: BIO216 PRACTICAL 2: ubiquity OF MICROORGANISMS DATE: 16-02-2012 INVESTIGATING THE ubiquitousness OF MICROORGANISMS INTRODUCTION The phrase, ubiquity of microorganisms, refers to the concept that microorganisms ar everywhere. well-nigh microorganisms occupy a diversity of niches, e.g Achaea screw get around in hot springs where temperatures atomic number 18 super high, and other microorganisms substructure pass away in solid rocks (Achey, 1999). Microorganisms ar very diverse, they embarrass bacteria, fungi, Achaea and protists. bacteria can live everywhere because there atomic number 18 so many opposite species all in all adapted to different purlieus, and can colonize that purlieu. They are 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 serious bacteria outnumber the harmful varieties. Microbes are vital to the environment because they participate in the estates 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 polished cultures from these mixed colonies in the environment, some(prenominal) techniques are available to use.

In this experiment, pour home parting and spread plate techniques were utilise to obtain pure cultures from the nation sample. Microorganisms from the mouth and distribute were obtained by rubbing sterile kindred canted applicator sticks on the teeth and palm of the lot and the rubbing the applicator sticks on the surface of alimental nutrient agar and mannitol flavor agar, respectively. Therefore, the aim of this study was to take apart and appreciate the type of microorganisms be in soils, mouth and hand and to estimate their quantities. METHODS In this experiment, microorganisms were harness from the body (mouth and hands) and soil sample. sterilized cotton plant tipped applicator was used to manoeuvre microorganisms...If you want to engender a full essay, order it on our website: Orderessay
