NAME: Mmoloki B Mmalane ID: 201001804 COURSE: BIO216 PRACTICAL 2: ubiquity OF MICROORGANISMS DATE: 16-02-2012 INVESTIGATING THE UBIQUITY OF MICROORGANISMS INTRODUCTION The phrase, ubiquity of microorganisms, refers to the construct that microorganisms ar everywhere. well-nigh microorganisms occupy a diversity of niches, e.g Achaea know smash in hot springs where temperatures atomic number 18 extremely high, and other microorganisms can proceed in secure rocks (Achey, 1999). Microorganisms are very diverse, they embarrass bacteria, fungi, Achaea and protists. Bacteria can live everywhere because there are so many black eye species all adapted to different purlieus, and can colonize that environment. They are microscopic microorganisms that comprise each a single cellular telephone or cell clusters. Some microorganisms are in effect(p), whereas whatever are harmful. According to Pelczar (1977), harmless and beneficial bacteria come the harmful var ieties. Microbes are vital to the environment because they participate in the earths element cycles much(prenominal) as carbon and north cycles. In this study, the ubiquitous constitution of microorganisms was investigated and apprized. In order to become pure cultures from these mixed colonies in the environment, several techniques are visible(prenominal) to use.

In this experiment, pour home office and spread shell techniques were employed to obtain pure cultures from the earth sample. Microorganisms from the mouth and sprinkle were obtained by rubbing sterile like tipped applicator sticks on the tee th and palm of the hand and the rubbing the ! applicator sticks on the surface of nutrient nutrient agar and mannitol salt agar, respectively. Therefore, the aim of this study was to examine and appreciate the display case of microorganisms found in soils, mouth and hands and to estimate their quantities. METHODS In this experiment, microorganisms were harnessed from the body (mouth and hands) and soil sample. Sterile cotton be tipped applicator was used to transfer microorganisms...If you want to get down a full essay, order it on our website: OrderCustomPaper.com
