-Albert Einstein Curiosity is the one way of asking questions‚ new findings will give birth to new questions; this is how science grows. I was in 12th standard‚ when I studied chemistry‚ physics‚ mathematics and biology as core subject. Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious

Staphylococcus aureus‚ Staphylococcus epidermidis‚ Alcaligenes faecalis‚ Escherichia coli‚ and Proteus vulgaris that were used in the lab‚ as well as comparing and contrasting the actual and factual results. Its unique pink rod shaped morphology was the first step observed under the microscope to identify its unknown characteristic. There were other methods utilized in lab as well: the Mannitol Salt and Eosin Methylene Blue Agar and the tryptic soy broth experiments. Oxygen reaction (aerobic vs. anaerobic)
