INVESTIGATING THE UBIQUITY 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 smash in hot springs where temperatures atomic number 18 extremely high, and other microorganisms can live in solid rocks (Achey, 1999). Microorganisms are very diverse, they embarrass bacteria, fungi, Achaea and protists. Bacteria can live everywhere because there are so many opposite species all adapted to different purlieus, and can colonize that environment. They are microscopic microorganisms that comprise each a single cell or cell clusters. Some microorganisms are in effect(p), whereas some are harmful. According to Pelczar (1977), harmless and beneficial bacteria outnumber the harmful varieties. Microbes are vital to the environment because they participate in the earths 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 pure cultures from these mixed colonies in the environment, several techniques are available to use.
In this experiment, pour home office and spread plate techniques were employed to obtain pure cultures from the earth sample. Microorganisms from the mouth and distribute were obtained by rubbing sterile like tipped applicator sticks on the teeth 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 type 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 plant tipped applicator was used to transfer microorganisms...If you want to engender a full essay, order it on our website: Ordercustompaper.com
