- "Biodegradation of Diesel Oil Using Bacillus Isolates" Environmental pollution is now a worldwide burning issue. There are many places in the Philippines, which are now contaminated by petrochemical sources, such as petroleum refineries and storage sites, paint manufacturing plants, gasoline service stations, gas emissions, etc. (EMB-DENR, 1997). Although the basic solution to the pollution problem is the elimination of the sources of these pollutants, there are however overriding economic, social and political factors that must be considered. An attractive remedial measure is the use of pesticide-degrading microorganisms for the environmental clean-up. Bacteria of the genus Bacillus are a group of versatile microbes known to degrade complex organic matters refractive to most microorganisms. Several species produce enzymes that catalyze the breakdown of petroleum products in water as well as in oil. These bacteria may provide the means of eliminating unwanted pollutants in the…arrow_forwardThe following carbon sources can be used for nutrition, by at least some heterotrophic organisms, except: CH3COOH CH3OH CO2 CH4 HCOOHarrow_forwardWhy do you suppose this habitat contains such a high microbial count?arrow_forward
