phytochemical analysis. Specifically‚ it answers the following: 1. What are the phytochemical content of the stickcane shoot extract? 2. Is there a significant difference in the antibacterial properties of the plant extract on Pseudomonas and Escherichia Coli as shown by the zone of inhibition? 3. Does the stickcane shoots extract exhibit antibacterial property? Significance of the Study The result of this study can be beneficial to the community. It can motivate the mass production of

FIRST FEW VACCINES Vaccination is a simple‚ safe and effective way of protecting babies and children against diseases. The risks from having these diseases are far greater than the risk of any minor side effects from vaccination. When your child is given a vaccine‚ their body responds by making antibodies‚ the same as if they had caught the disease but without getting sick. Then their body produces antibodies to destroy the vaccine and these stay in your child’s body and protect them against the

Among the reports‚ several have shown the relationship between GMO cytotoxicity as well as the teratogenic potential in mammals. Specifically the toxins glyphosate‚ and Bacillus thuringiensis (Bt) present a combined area of concern as these herbicide resins and insecticidal toxins are present in Roundup-tolerant GM plants such as corn‚ soybeans‚ canola‚ cotton‚ sugar beets‚ and alfalfa.

PSBPP103 Differential Gram’s staining EXPERIMENT NO. 1 AIM: THEORY: Page No: C1 Date: To Gram stain the given bacterial suspension and to differentiate between gram positive and gram negative organism. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes

Unknown #1 Vomit Serratia marcescens & Bacillus cereus Biol 251 Microbiology 5/14/2009 Introduction The purpose of this study is to differentiate and identify two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The
