There were ten bacteria species possibilities: Stahylococcus epidermidis‚ Bacillus subtilis‚ Escherichia coli‚ Serratia marcescens‚ Sarcina lutea‚ Pseudomonas fragi‚ Micrococcus luteus‚ Alcaligenes faecalis‚ Clostridium sporogenes‚ and Micrococcus roseus. There were several qualitative tests that could be conducted to determine the identity of the unknown species‚ for example‚ Gram staining‚ Fermentation‚ Catalase‚ Oxidase‚ Starch Hydrolysis

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 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

while organism B was oxidase negative. Then I decided I would run the biochemical tests on organism B. I observed that organism B was non-motile and did not produce endospores. With these results‚ I narrowed down the possible species to Enterococcus faecalis‚ Enterococcus faecium‚ Lactococcus lactis‚ Leuconostoc mesenteroides‚ Pediococcus parvulus‚ and Streptococcus mitis. After obtaining some background information on these bacterial strains in the Strain Information handout‚ I decided to inoculate

workers in the workplace. Why is it becoming more prevalent in Australian health-care sectors. What is Vancomycin-resistant enterococci (VRE)? Vancomycin-resistant enterococci are enterococcus strains‚ such as Staphylococcus faecalis‚ now called Enterococcus faecalis that are resistant to the antibiotic vancomycin. Enterococci infections are the most common type acquired by hospitalised patients. Vancomycin was the last-line antibiotic for hospital treatment of serious methicillin-resistant

EFFECT OF BIODEGRADABLE SM PLASTIC BAG IN DIFFERENT SUBSTRATE ABSTRACT The purpose of this Investigatory project is to determine the effect of different substrates on the biodegradability of SM plastic bags. The materials needed are: 6‚ 1-litre glass jars; 6‚ 7”x9” aluminums trays; 12 pcs. 3”x4” SM plastic bags; 500g loam soil; 500g compost soil; 500mL seawater; 500mL tap water; Analytical balance; Graduated cylinder; and Weighing scale. The procedure involved cutting the SM plastics bags

Enterococcus By Richard Guilford Enterococcus Enterococcus‚ or more appropriately enterococci‚ are a family of bacteria in the division firmicutes (meaning strong skin and referring to the cell wall) and the class bacilli (which refers to its rod like shape). They look just like streptococcus bacteria from physical characteristics alone. In fact‚ members of the genus Enterococcus were classified as Group D Streptococcus until 1984 when genomic DNA analysis showed that a separate genus classification

the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different species.
