The Effects Of Microorganisms And Its Effects On The Environment

Introduction: Microorganisms have been used by human beings to their benefit for centuries. Ancient biotechnology utilized yeast to make bread and wine – perhaps well before they even knew that tiny microbes were causing bread to rise, or grapes to ferment! In the modern day, the use of microbes has extended so far as to actually help us reverse the damages we cause to the environment. One such environmental application of microorganisms is Bioremediation – the use of either indigenous or Hydrocarbonoclastic bacteria (HCBs) to rapidly digest hydrocarbons from oil spills. According to a recent study by The International Tanker Owners Pollution Federation Limited, between 2010 and 2012 there were 21 tanker spills, 5 of which were above 700 tons (2012). The use of often naturally occurring bacteria to digest these oil spills is now being heavily studied and implemented as a means to clean up these disastrous oil spills. Biostimulation (the addition of inorganic nutrients that would normally be limiting) has been studied as a potential measure to encourage indigenous microbes to increase their rate of hydrocarbon digestion in order to expedite the process of oil spill clean-up. Bioaugmentation, the process of introducing HCBs to a native community to increase efficacy of bioremediation, has also been studied in addition to the effect of the addition of surfactants in both cases (McKew et al., 2007). Because oil-spills tend to contain every
