unknown microorganism relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The focus of this paper will be on the description of the just one of the three bacteria and some of its effects on humans. The first test done was a differential stain

INTRODUCTION Cassia fistula Linn. (Leguminosae) is a very common plant and is widely known for its medicinal properties. In the Indian literature‚ this plant has been described to be useful against skin diseases‚ liver troubles‚ tuberculous glands and its use in the treatment of rheumatism‚ hematemesis‚ pruritus‚ leucoderma‚ and diabetes.[1‚2] Besides‚ it has been found to exhibit anti-inflammatory and hypoglycemic activity and widely used as a mild laxative suitable for children and pregnant women

has more than 100 phytochemicals. It is used as sugar substitute. The extracts from leaves are used for the microbial assay and study the antimicrobial activity. The microbes used for the testing the activities are E.coli‚ Staphylococcus aureus‚ Bacillus subtilis‚ Salmonella typhi‚ Aspergillusniger‚ Candida parapsilosis‚ Trichophyton rubrum. With different concentrations of the extracts starting from 2.5µg/ml‚ 5.0µg/ml‚ 7.5µg/ml‚ 1.0µg/ml and the highest activity is shown by Staphylococcus aureus

Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the major factors in determining that microbe’s ecological niche‚ and often allow for that microbe to be useful in industrial processes or responsible for biogeochemical

seeing bubbles‚ I ruled out Streptococcus lactis. My organism did have the catalase enzyme; meaning it was either Bacillus subtilis or Staphylococcus. To distinguish the two‚ I performed the simmons citrate test on them. Since the tube stayed green I confirmed that my organism was Staphylococcus. My organism B could not degrade citrate‚ so that meant my organism was not Bacillus subtilis. In conclusion‚ my unknown organisms were Staphylococcus and Enterobacter aerogenes. REFERENCES Kidane‚
