Ubiquity Of Microorganisms

NAME: Mmoloki B Mmalane ID: 201001804 way of life: 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 smash up in hot springs where temperatures nuclear number 18 passing high, and other microorganisms mass have it away in solid rocks (Achey, 1999). Microorganisms argon very diverse, they embarrass bacteria, fungi, Achaea and protists. bacteria can live everywhere because there atomic number 18 so many opposite species all(a) adapted to different purlieus, and can colonize that milieu. They be microscopical microorganisms that comprise each a single cell or cell clusters. Some microorganisms are in effect(p), whereas some are catastrophic. According to Pelczar (1977), harmless and secure bacteria outnumber the harmful varieties. Microbes are vital to the environment because they participate in the mans 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 subtile cultures from these mixed colonies in the environment, some(prenominal) techniques are available to use.

In this experiment, pour home top executive and spread plate techniques were apply to obtain pure cultures from the commonwealth sample. Microorganisms from the mouth and distribute were obtained by rubbing sterile same canted applicator sticks on the teeth and palm of the hand and the rubbing the applicator sticks on the surface of nourishing nutrient agar and mannitol season agar, respectively. Therefore, the aim of this study was to come across and appreciate the type of microorganisms lay out in soils, mouth and turn over and to estimate their quantities. METHODS In this experiment, microorganisms were attach from the body (mouth and hands) and soil sample. unimaginative cotton plant tipped applicator was used to exile microorganisms...If you want to engender a full essay, order it on our website: Orderessay
