bacteria would be directly increase overall growth. We tested these hypotheses by preparing five different petri dishes‚ each containing cultures of the bacteria E. coli. In two of these dishes (set up identically)‚ containing plain agar with no additional nutrients‚ we added small amounts of Penicillin to half the plate and water to the other half. We then observed the plates after one week’s time. For the other three plates we stored one dish at 4°C‚ one at 22°C‚ and one at 37°C; no antibiotics

The Use Of Jatropha Multifida In Treating Wounds ABSTRACT A study on the effectiveness of Jatropha multifids latex in treating wounds was conducted. White mice were used as test subjects. The test subjects were distributed into three treatment groups‚ with each group having three test subjects. An incision measuring approximately 1 cm long was made on each test subject. The first group was treated with a leading antiseptic‚ Betadine‚ the second group with Jatropha multifida‚ and the third group

Genetic Transformation of Bacteria Abstract The transformation of bacteria was successfully carried out using a plasmid carrying a gene that codes for green fluorescent protein‚ which gives a signature green glow reminiscent of a jellyfish. This gene‚ however‚ is only active when the sugar arabinose is present. A gene coding for antibiotic resistance was also found within the plasmid and served as a means to verify that transformation had indeed taken place. The hypothesis was that the bacteria

Bacteriological examination of water performed through most probable number analysis showed that MPN index per 100ml of the water sample were found to be maximum‚ presence of coliform bacteria was confirmed using EMB and nutrient agar medium which clearly indicates that the water could not be used for domestic and agricultural purposes. Eco toxicological studies done on the invertebrate system zebra fish showed deleterious effects which is depicted in table-2. The zebra fish

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

s Disease can be divided in two main groups infections and non-infections. Infectious diseases are diseases that can be spread or transmitted from one organism to another. Non – infectious diseases cannot‚ be spread from one person to another. Infectious Diseases Infectious diseases are generally caused by microbes known as pathogens. Pathogens invade the host and can cause changes in the body that stop parts‚ or all‚ of the body working correctly. Pathogens contain antigens that are made of

Materials and Methods The procedure for all tests performed was taken from Leboffe and Pierce’s Microbiology: Laboratory Theory and Application. The first and easiest data to record is the color of the bacterial colonies on a nutrient agar plate. Growing the cultures on the agar can be done by streaking a plate so as to isolate the bacterial colonies. Then separate the two colonies that are different in growth on a TP plate by using the same streaking techniques with a sterile loop. Both bacteria will

this process the UV light was used periodically to observe the condition of the bacteria in the micro tubes. After a few times of incubation on ice‚ hot water and room temperature‚ LB nutrient broth was added to the mixture to help the bacteria with its growth. These mixtures were then added to the appropriate agar plates for observations and place them in the incubator. After 10 – 16 hours of incubation‚ to obtain conclusive results‚ the DNA sequence must be read. In order to achieve this task‚
