The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

SYNTHETIC EXPLOITATION OF ENZYMES: BIOCATALYSIS IN ORGANIC SOLVENTS: FUNDAMENTALS ENZYMES IN ORGANIC SYNTHESIS 1. Enzymes catalyze a broad spectrum of reactions with high turnover numbers. Rate enhancements approach 1012 fold. 2. Enzymes may accept a wide range of substrates. 3. Enzymes are highly regio and stereoselective. 4. Enzyme reactions take place under mild conditions; this minimizes problems of isomerization and racemization. 5. Enzymatic processes are less hazardous and polluting

Mechanisms of Acetaminophen-lnduced Liver Necrosis By Jack A. Hinson‚ Dean W. Roberts‚ and Laura P. James Acetaminophen (paracetamol‚ N-acetyl-p-aminophenol; APAP) is widely used as analgesic and antipyretic drug. At therapeutic doses‚ acetaminophen is safe to be used. Acetaminophen other than aspirin and ibuprofen has only weak anti-inflammatory properties. At higher doses‚ acetaminophen produces a centrilobular hepatic necrosis that can be fatal.

Admiral butterflies (genus Limenitis) are a particularly appealing system to address questions regarding wing pattern evolution and speciation. This genus is unusual among other butterflies in that mimicry has evolved multiple times and hybridization is frequent between wing pattern forms. An interesting fact of wing pattern evolution within this genus is the apparent differences between the largely stereotypic Paleartic fauna and the highly variable Nearctic forms of butterflies. Palearctic

The phytochemicals identified in this plant were lipids‚ flavonoids‚ alkaloids‚ saponins‚ tannins‚ lignins‚ glucocapperin‚ and polyphenols (Al-Said et al 1988; Calis et al. 2002; Manikandaselvi and Brindha 2014). Even though it has been used in traditional Indian system of medicines for various human diseases‚ the summation of its medicinal properties is lacking. C. spinosa L. has

Introduction Biogeochemical cycles are important to the sustainability of all life. Chemical elements necessary for the growth and reproduction of all organisms have a limited quantity on earth at any one time‚ other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms

Dukan Diet The Dukan Diet‚ also known as the princess diet‚ is a diet plan originating in France. It is a protein-based diet designed by French doctor Pierre Dukan‚ nutritionist and dietician. The Dukan Diet‚ or Dukan method proposes a healthy eating plan which is based on how primitive man used to eat when we were hunter-gatherers. It includes 100 foods‚ of which 72 are animal sourced and 28 come from plants. And you can eat as much as you like‚ as long as you stick to those 100 foods. The aim

plant extracts could be responsible for their free radical scavenging activity and studies on fruits and vegetables also show a relationship between phenolic content and antioxidant activities (Omken et al.‚ 2009). The antioxidant potential of polyphenols arises due to their high reactivity as hydrogen or electron donors‚ which can stabilize and delocalize the unpaired electron and chelate metal ions (Rice-Evans et al.‚ 1997). In agreement with the above report‚ the ethyl acetate fraction (ABE) exhibited
