UNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others

the mechanism of action for cranberries is preventing bacteria to bind to “host cell surface membranes”. The bacteria that causes a urinary tract infection is Escherichia coli‚ which is more commonly called E. Coli. Cranberries contain phenol compounds known as proanthocyanidins. These proanthocyanidins‚ in particular‚ “inhibits the Escherichia coli bacteria from attaching to the lining of the urinary tract.” (Lynch‚ 2004) So whether it is a glass of cranberry juice‚ a cranberry cocktail‚ or a cranberry

Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is

L. fixed oil was investigated. Agar cup diffusion assay was performed against two fungal species (Candida albicans and Aspergillus niger)‚ two gram positive bacteria (Staphylococcus aureus and Bacillus subtilis) and two gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa). Ampicillin‚ gentamycin and clotrimazole were used as positive controls. Antimicrobial activity was shown by all the species except E.coli and P. aeruginosa. Oil showed a highest activity against Candida albicans

Imperata cylindrica as an Antibacterial Agent for Escherichia coli INTRODUCTION a. Background of the Study We all know that bacteria are everywhere. Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. One example of bacteria is E .coli is a bacterium that is commonly found in the gut endotherms. E. coli and related bacteria constitute about 0.1% of gut flora‚ and fecal-oral
