substrate concentration‚ enzyme concentration‚ temperature and pH on hydrolysis and solubilization of corn gluten as well as enzyme stability. The corn gluten was hydrolyzed by Alcalase enzyme (a bacterial protease produced by a selected strain of Bacillus licheniformis) that was chosen among five commercial enzymes examined. The optimum process conditions for hydrolysis and solubilization were obtained as 30 g L–1 substrate mass concentration‚ 2.5 mL L–1 enzyme concentration‚ 55 °C and pH 8. Under

Measles: is an infection of the respiratory system caused by a virus‚ Symptoms: include fever‚ cough‚ runny nose‚ red eyes and a rash. Measles: is spread through respiration‚ the contact with any infected person in any way‚ including sex‚ saliva‚ or mucus‚ can cause infection making it highly contagious. It lasts from two to four days prior‚ until two to five days following the onset of the rash. Signs: and symptoms of measles include four-day fevers and the three Cs — cough‚ coryza (head cold)

Increases in temperature and the presence of light affected the stability of this pigment. Results demonstrate that this pigment exhibits
Premium Gram staining Staining
Bacteria which stain purple are called Gram-positive while stained pink colour are called gram negative bacteria. From the results‚ purple stained are obtained for E.coli and S.aurues . E.coli is a rod shaped bacteria‚ therefore it described as bacillus. S.aureus has irregular grapelike clusters‚ therefore is it coccus bacteria. Through this experiment‚ purple stained obtained for both bacteria‚ E.coli and S.aureus. But compared to same experiment carried out by others‚ E.coli should be pink stained

Microorganisms are tiny‚ small living things which can not be seen with eyes. They spread everywhere around the world. Most people think that microorganisms are harmful to the environment. Humans exploit these small living things hundreds of years ago. Science has developed and scientists have established new science related to microorganisms‚ it is called microbiology. In this essay‚ I will talk about one of the oldest and most widespread microorganisms in our planet‚ bacteria. Bacteria lives everywhere

Tuberculosis [pic] Salena Nowak Physiology 22 Dr. Jennifer Gray April 15‚ 2008 Abstract Tuberculosis (TB) is an acute infectious disease. It is found primarily in the lungs‚ but is also seen in any tissue of the body. This disease has infected more than one third of the world’s population. Most cases are seen in African and European countries. Tuberculosis has killed more people than any other disease in history. Robert Koch was the person who

that cell size had anything to do with the initiation of DNA replication in bacteria. The objectives and hypothesis was clearly stated in the paper. In order to find the answer to their question‚ the researchers used Escherichia coli (E. coli) and Bacillus subtilis (B. subtilis) in their experiment. Both E. coli and B. subtilis are common and well known bacteria that are used in research. They took the E. coli and B. subtilis and placed them in specific media for each step the in process of replication

STATEMENT OF PURPOSE FOR FOOD SCIENCE The progression of technology and the effects it had on civilization has always fascinated me and generated profound interest in me. My decision to choose Food Science is not an impetuous decision‚ rather it was developed over a time. Since I was a kid I have seen my parents and grandparents using different cooking methods from time to time. My interest in finding the scientific reason behind their cooking practices grew strong as I grew older. Usage of
