Student: Yi-Ren Wang Course: BIO-205 BD2 Microbiology Instructor: Dirk VandePol Date: 6/21/2013 Streak Plate Isolation for Obtaining Pure Culture 1. When an agar plate is inoculated‚ why is the loop sterilized after the initial inoculation in put on? Ans: We use agar plate to inoculate microbes by zipping the loop on the agar several times. We streak on the agar plate four time‚ propose is to isolate the unknown bacteria. Therefore‚ the first time to streak on the plate‚ there are

P1: you must explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. P2: you must explain how pathogenic microorganisms grow and spread. In this assignment I am going to explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. I will then explain how pathogenic microorganisms grow and spread. Infection is the process where germs enter a susceptible area in the body‚ where they multiply‚ resulting in disease. Colonisation is where microbes are present

Antibiotics Vs Tea Tree Oil To determine the effect of various different antibiotics and Tea Tree oil on the Bacillus subtillis different types of bacteria. I will test six antibiotics and the Tea Tree oil on Bacillus subtilis. I will test tetracycline‚ chloramphenicol‚ ampicillin‚ sulphatriad‚ penicillin G and Streptomycin. I would also like to see if Bacillus subtillis shows resistance to Antibiotics or to Tea Tree oil. The use of penicillin is being reduced because of the

CALLUS INDUCTION By: Sonali Pradhan‚08-11-2013 ABSTRACT The present study describes a reliable method for callus induction of Hybanthus ennaspermus‚an important medicinal plant plant. Calli were in vitro initiated from leaves segments using Murashige and Skog (1962) basal media. The effect of NAA (_-naphthalene acetic acid) and 2‚4-D (2‚4-Dichlorophenoxy acetic acid) on callus induction was investigated. It was found that growth regulators and their concentrations have obvious effects on the

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures
