(group B) (group A) Lineage Moises Dominguez You were given an unknown bacterium to identify. You did gram staining and look at the slide under the microscope. You saw purple coccus- shaped cells in cluster. Then, you grew the bacteria in the thioglycolate broth and incubated at 37C. After 24 hours of incubation, you made an observation and found your bacteria growing on tip of the broth, no growth was seen at the middle and bottom of the broth. You also did saw a bubbling upon adding hydrogen peroxide to the bacteria. It is coagulase negative. The Kirby Bacur Assay show no zone of inhibition to antibiotic novobiocin. Based on the information obtained, what is your unknow bacteria? S. saprophyticus S. epidermidis S. agalactiae

Modes of Nutrition

It is a biological process of providing or obtaining food that is necessary for growth and health. It includes many physiological processes - absorption, ingestion, assimilation, catabolism, excretion, etc. In biology, the science that deals with nutrition's physiological and chemical processes are called "nutritional science."
