principals of living microbes and identifying my unknown bacteria through numerous biochemical and metabolism tests‚ with the outmost confidence‚ Proteus vulgaris had the precise qualifications. The point of this report is to further explore the identification of my unknown bacteria by revealing the results of the experiments and comparing them to the other six known bacteria: Micrococcus luteus‚ Staphylococcus aureus‚ Staphylococcus epidermidis‚ Alcaligenes faecalis‚ Escherichia coli‚ and Proteus vulgaris

(Table 1) * In order to test carbohydrate catabolism under anaerobic conditions we tested cultures of Pseudomonas aerugenosa‚ Escherichia coli‚ and Alcaligenes faecalis in tubes containing a glucose medium. After inoculating each tube with each of the bacteria 5mm of mineral oil was poured into one of the tubes containing bacteria to observe anaerobic respiration and while one remained without mineral oil.

OBJECTIVE: 1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a

between 4 and 11 depending on the species. The optimum temperature also varies by species. History Catalase was first noticed in 1811 when Louis Jacques Thénard‚ who discovered H2O2 (hydrogen peroxide)‚ suggested its breakdown is caused by an unknown substance. In 1900‚ Oscar Loew was the first to give it the name catalase‚ and found it in many plants and animals. In 1937 catalase from beef liver was crystallised by James B. Sumner and Alexander Dounce and the molecular weight was worked out

Screening and identification of rhizobacteria isolated from heavy metal contaminated soils INTRODUCTION As a result of human activities such as mining‚ agriculture and industrial activity‚ heavy metal pollution has become one of the most serious environmental problems today. Elevated levels of heavy metals not only decrease soil microbial activity and crop production‚ but also threaten human health through the food chain. Soil microorganisms can degrade organic contaminants‚ while metals need

prevent infection by keeping a sterile environment and to follow aseptic techniques at all times ("Staphylococcus epidermidis"). Staphylococcus epidermidis is a gram-positive bacterium‚ whose species belongs to the genus Staphylococcus. It was an unknown species until 1884‚ when microbiologist‚ Fredrich Julius Rosenbach‚ distinguished it from Staphylococcus aureus. He had discovered that S. epidermidis grew in white colonies‚ whereas S. aureus grew in yellow colonies. As a result of those findings
