Isolation‚ Expression and Cloning of Lactate Dehydrogenase Gene from Lactobacillus bulgaricus Lactobacillus bulgaricus is used for industrial production of yogurt mainly because of his fermentative capability. In this experiment‚ the gene encoding the enzyme lactate dehydrogenase [ldhA] from the bactaria was isolated and cloned. The expressed ldhA gene was inserted into pET28b plasmid vector. The resulting recombinant pET28b-LdhA expression vector was then transformed after introduction into E.

In this research paper‚ it will describe two bacteria that are helpful and sometimes harmful to humans and the environment‚ which are E. coli and Lactobacillus Acidophilus. E. coli E. coli is the bacteria that live in the intestines of humans and animals. It and other bacteria help develop the body and keep your intestines healthy. It also provides vitamins to the body.

Clinical Decision Making A complete medical history was obtained from the patient. Following a discussion of her concerns‚ a physical exam‚ including a pelvic and bimanual exam was performed. Swabs of the vaginal area were collected and placed under the microscope. The results were concurrent with the suspected diagnosis of bacterial vaginosis. The physician explained the results of the swab samples and offered the patient different treatment options. Pathophysiology Bacterial Vaginosis (BV) is

running head: UNIT 10. ASSIGNMENT Environmental Microbiology With so much advertising for various antibacterial products‚ many people have gotten the impression that all bacteria are harmful and that maybe the Earth would be better off if all bacteria were eliminated. What would life be like in a bacteria-free world? Bacteria help decay materials and put vitamins and minerals‚ and gases into the atmosphere. Without them the world would be able to produce little food. Bacteria are woven into

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine
