CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

2.4 Mechanism Of Phosphate Solubilization: In contrary to Nitrogen soluble Phosphorous is not supplied to plants by atmosphere . Due to this reason the primary and secondary minerals and/or organic compounds are the source of P to great extent. In soil solution concentration of phosphorous is least as compare to other nutrients and ranges from0.001 to 1mg/ml Brady and Weil (2002 ).There are widely three categories of P compounds in soil: (i) compounds which are inorganic‚ (ii) organic compounds

Fermentation of Lactose Test‚ the Sulfide Indole Mobility (SIM) Test‚ the Nitrate Reduction Test‚ the Protein Hydrolysis Test‚ the Catalase Test‚ and the Cytochrome Oxidase Test. The microbes that were tested during this lab were: Escherichia coli‚ Bacillus cereus‚ the unknown‚ Proteus vulgaris‚ Staphylococcus epidermis‚ Enterobacter aerogenes‚ the control‚ and Pseudomonas fluorescens. The microbes tested during these various tests were looking for which would: reduce sulfur/produce sulfate‚ produce

to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different species. After one week they were observed

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 resistance

We have a patient that may be infected with an unknown bacterial infection; we’ve collected a sputum sample and will be testing for one of the following genera: Bacillus‚ Escherichia and Mycoplasma. In order to determine which one of the three may be the source of the infection we have to recognize the characteristics of each one and the staining protocol needed to identify them. All three of the above mentioned

on the body of marine animals or internal organs of both aquatic and terrestrial animals. Amoeba reproduces asexually by binary and multiple fissions. They eat algae‚ bacteria‚ other protozoan‚ and tiny particles of dead plant or animal matter. Bacillus: They are rod shaped‚ gram positive bacteria found in soil and water. The largest are 2m across and 7m long. Most are aerobic but some under certain conditions can be facultative anaerobes. Each bacterium creates only one spore‚ which is resistant
