spills asks for effective solutions for the environment. Bioremediation techniques have become a major mechanism for removing oil residues on the affected shorelines. Among the different techniques to enhance natural biodegradation by indigenous microorganisms‚ seeding of new bacteria and fertilizing the indigenous populations have attracted the most interest. The application of nutrients as nitrogen and phosphorus in the form of fertilizers have shown to be most effective in accelerating the biodegradation

ABSTRACT In todays world of ever evolving genetic mutations the incidence of drug resistant forms of microorganisms are on the rise. The importance of identifying these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine

An antibiotic is defined as a substance that is produced by microorganisms that in miniscule amounts inhibits the growth of another microorganism (Tortora 2010). Antibiotics can be found naturally in the environment or they can be manufactured with chemicals. They are specifically designed to hinder the growth and development in other microbes. Yet‚ these antimicrobial drugs should not cause extreme harm to normal microorganisms (Tortora 2010). The vast majority of antibiotics that have been

capacity ranges from three to six gallons depending on the type of feed. It’s lines with small projections called papillae; this increases the absorptive surface of the rumen. This compartment is also known as the paunch‚ it contains many microorganisms. These microorganisms also convert components of the feed to useful products such as essential amino acids‚ B-complex vitamins and vitamin K. Volatile fatty acids are absorbed through the rumen wall and can provide as much as eight percent of the animal’s

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that

effective. The microorganisms that retain the crystal violet and iodine mixture appear purplish brown under microscopic examination. These microorganisms that are stained by the Gram’s method are classified as Gram positive. Others that are not stained by crystal violet are referred to as Gram negative‚ and appear in shades of red. Gram staining is based on the ability of bacteria cell wall to retaining the crystal violet dye or methylene blue. The cell walls for Gram positive microorganisms have a higher
