ASSAYING PLANT SUBSTANCES FOR ANTIBACTERIAL ACTIVITY PURPOSE To test plant extracts to see if they possess antibacterial activity. PROCEDURE First create a list of plant extracts being tested and choose 2 extracts per group. The plants being tested are Oregano‚ Tea tree‚ Eucalyptus and Colloidal Silver. Obtain two nutrient agar plates and using a permanent marker draw four quadrants on the bottom of each agar plate. Using a sterile pipet transfer 250 ml of E. coli broth to the middle of

Judson Cotterman III 4/6/2012 Section 185-35L Assignment #3 Gram-positive Pathogenic Cocci Discussion My original hypothesis for the individually collected throat culture on Blood Agar Plates‚ that it would show a mixture of alpha‚ beta‚ and gamma hemolysis‚ was based on the results of the class control samples of S. pneumonia‚ S. aureas and S. epidermis. In these controls S. pneumonia shows alpha and beta hemolysis while S. aureas and S. epidermis showed beta and gamma hemolysis respectively.

1. What are the advantages and disadvantages of the different types of light and electron microscopes discussed in Chapter 3 that are used to study microorganisms? Focus your response in terms of the following parameters The disadvantage of using a light microscope is its inability to magnify a specimen as great as an electron microscope. An electron microscope can magnify up to 500‚000 times‚ whereas‚ a light microscope can only magnify an object up to 2000 times. The resolving power or resolving

agency NASA selected Gram Power’s technology among the top-10 cleantech innovations from around the world. Two fresh graduates from the University of California Yashraj Khaitan and Jacob Dickinson founded GRAM POWER which enables villagers to generate and store renewable energy from biomass‚ solar or wind on-site. While on a university project they came to know about the scarcity of electricity in villages‚ this goaded them to devise energy solutions for villagers. This year‚ Gram Power set up India’s

belts‚ caps‚ etc‚ are the most preferred clothing for today’s youth. This study discusses compositions and methods of reducing or preventing back staining of indigo dyes on the weft yarn and pocket of denim garments. The dye‚ as it is removed from the denim material‚ post treatment with cellulase or by a conventional washing process may cause ‘back staining’ or ‘redeposition’ on the denim material; e.g : re-coloration of blue threads and blue coloration of white threads‚ resulting in less contrast between

survivability in artificial gastric juice ABSTRACT: Two probiotic drinks were investigated in vitro to test their ability to survive acidic conditions and their probiotic factors. Both the products: Actimel and Yakult contain gram-positive bacteria‚ but Actimel also has a gram-negative bacteria. The ability to survive was investigated by adding artificial gastric juice to the products and incubating at different times. Actimel and Yakult were both able to survive the gastric juice. Actimel produced
