Bacteria are unicellular and ultra-microscopic organisms‚ yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly‚ others are very harmful as they cause various plant and animal diseases. Bacteria are considered as our friends and foes due to their beneficial and harmful activities. Their economic importance can be studied under

HYDRO-ECOSPHERE Hydro-ecosphere is considered as a more suitable habitat for microorganisms than the atmosphere and lithosphere‚ mainly because hydrosphere contains water‚ which is important in microbial metabolism (Atlas and Bartha‚ 1993). The unique properties of water are also attributes of hydrosphere as a suitable habitat. Due to polarity of water (slightly negative and slightly positive)‚ water is considered as a great solvent‚ capable of forming hydrogen bonding. Large heat

Oxidase test‚ and the Nitrate test were used to help identify the unknown Gram-positive bacterium. The coagulase test was negative‚ therefore of all the possible Gram-positive bacterium the unknown organism could either be Staphylococcus simulans or Micrococcus luteus (Table 3; Lancaster and Bennett‚ 2012). Next‚ the Nitrate test was used to differentiate between the two remaining possibilities. Since the unknown Gram-positive bacterium resulted in a negative for Nitrate‚ the organism was identified as
