doctor before taking omega-3 fatty acids if you take blood thinning medications. To avoid a potentially toxic build-up of vitamin A‚ choose omega-3 fatty acid products where the bulk of vitamin A has been removed.

Experiment 9: Growth curve of Serratia marcescens Abstract Bacteria grows by binary fission. The aim of this experiment is to follow the growth of Serratia marcescens in nutrient broth at 37oCby recording the changes in turbidity (cloudiness) by measuring the absorbance of visible light (600 nm) and also to prove that there is an increase in the cell number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance

The result of this study showed that bee bread extract has a protective effect in aluminum induced anemia and it significantly ameliorates hepato-renal toxicity and reduces the elevated CRP level and monocytes and leukocytes counts encountered after aluminum exposure. Aluminum alone caused significant anemia‚ elevation of BUN‚ CRP‚ leukocytes and monocytes counts and liver enzymes‚ ALT and AST‚ and deceased creatinine clearance. Chemical analysis and antioxidant study showed that it contains fat

Your answer for each question should be a minimum of 150 words (half page). Cite your sources after each question. 1. In 1835‚ Bassi showed that a fungus caused a silkworm disease‚ and in 1865 Pasteur discovered that a protozoan caused another silkworm disease. Why do we use Koch’s postulates instead of Bassi’s or Pasteur’s postulates? Koch was the first scientist to prove that bacteria actually cause disease. He scientifically demonstrated that a disease is caused by a particular organism

How would you convince a friend that microorganisms are more than just disease causing agents? An entire kingdom of microorganisms was brought into life 3 billion years ago. Since then «the earth is a fundamentally a microbial planet‚ to which the micro-organisms are recent the relatively unimportant additions» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular

acid bacteria are present. In additional to the usual alcoholic fermentation‚ yogurt may undergo other changes caused by microorganisms: 1. The lactic acid fermentation of sugars‚ mostly by heterofermentative lactic acid bacteria such as Lactobacillus pastorianus‚ Lac. bevis and by homofermentative lactic acid bacteria such as Lac. arabinose. 2. The fermentation of organic acids of the yogurt by lactic acid bacteria e.g.‚ Lac. pastorianus‚ malic acid to lactic and sucsinic acids‚ citric

2.1 Bioreactor configuration: Stirred tank bioreactor is a cylindrical vessel. The semi-circle bottom of the cylindrical vessel was made of stainless steel with an internal diameter of Ti=8 inch‚ outside diameter 10 inch and height of vessel 24 inch giving it a 3:1 height to diameter ratio for the working volume (Group et al.‚ 2006). The experiments were performed in batch conditions at different temperature‚ pH and atmospheric pressure. The liquid phase was deionized water (28± 0.5°C). Filtered
