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

amylase on the breakdown of starch. MATERIALS These were the materials used: four starch/ agar plates‚ a marker pen‚ 1mm graph paper ruler‚ 8mm cork borer‚ forceps and template for cutting holes‚ 1% Amylase‚ water‚ incubator set at 5‚ 20‚ 40 and 60 degree Celsius. METHOD This was the experimental procedure carried out: the materials above were collected. Six wells were cut using cork borer in the agar which was in the plate and removed the bored one with forceps. The incubate temperature‚ the

A pure culture is usually derived from a mixed culture (containing many species) by methods that separate the individual cells so that‚ when they multiply‚ each will form an individually distinct colony‚ which may then be used to establish new cultures with the assurance that only one type of organism

Biochemical Test – Enterobacteriaceae Bacterial spp incapable of fermenting glucose cannot utilize lactose. 2 enzymes necessary for a bacterium to take up lactose: A. β-galactoside permease – facilitates the entry of lactose molecules to bac cell wall B. β-galactosidase – breaks down lactose into β-D glucose and β-D galacatose LF possess both enzymes NLF do not possess β-galactosidase LLF do not possess β-galactoside permease Glucose fermenters only (true enteric pathogen)

A series of step such as ice baths and heat shocks were put into place to allow for transformation to occur and then the solutions were placed on an agar plate and incubated at 37° for a week. Our results failed to reject our hypothesis and predictions and thus resulted that there was indeed a high percentage of transformation efficiency. The agar plate with the ampicillin environment but no plasmid uptake resulted in no growth while the rest that were a variation between ampicillin environment

When these opportunities are presented to parents‚ most of them would embrace the idea of creating the best babies possible and they would expect from other parents the same. Although Agar denies there will be any moral obligation upon parents these situations might feasibly emerge.

Nicole Hain Bio 110 Sordaria fimicola Lab Report Introduction “Evolution Canyon” consists of two slopes in Israel that are close in proximity‚ but have a huge difference in environment. This makes the slopes a good model system for exploring evolution‚ especially because they’re so close to one another. The South Facing Side (SFS) receives more sunlight than the North Facing Side (NFS). This extreme sun exposure causes the South slope to have drought and arid conditions whereas the North side has

Introduction: Biological organisms are classified uniformly in order to easily categorize and identify organisms. This classification‚ or taxonomy‚ uses the genus name followed by the species name‚ in Latin. By having a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are
