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…

The Gram stain works because of differences in the O 1) cell membranes O 2) genetic characteristics O 3) capsules O 4) antigens O 5) cell wallsDevelopment of Resistance to antimicrobial drugs: What is the difference between a natural, semisynthetic, and synthetic antibiotic? How was the first natural antibiotic discovered? (To answer this question, identify the antibiotic, distinguish between the fungus and the antibiotic, explain where the antibiotic came from, and explain how people knew the antibiotic had antibiotic properties.) Give an example of a strain of bacteria (Genus and species) that is now resistant to commonly used antibiotics (identify the specific antibiotic). Describe the physiological mechanism used by individual bacteria to resist the antibiotic listed in part “3” of this Thought Question. For example, the mechanism could be modification of drug, modification of target, prevention of drug penetration, overproduction of target, or target mimicry. (This means that you must choose a strain of bacteria that we know the characteristic of the bacteria that allows the bacteria to be resistant.)
