biopolymers‚ such as polysaccharides‚ polyesters‚ and polyamides‚ are produced by microorganisms. Microorganisms are used for the biotechnological production of biopolymers with tailored properties suitable for high-value medical application such as tissue engineering and drug delivery. Microorganisms are used for the biosynthesis of xanthan‚ alginate‚ cellulose‚ cyanophycin‚ poly(gamma-glutamic acid)‚ levan‚ hyaluronic acid‚ organic acids‚ oligosaccharides and polysaccharide‚ and polyhydroxyalkanoates

Having the necessary nucleus which holds the cells DNA and produces ribosomes that help in the synthesis of proteins. Surrounding the nucleus is the rough and smooth endoplasmic reticulum. The two help break down and store materials. Rough stores and transports synthesized proteins‚ while smooth stores and transports synthesized lipid‚ steroid hormones

alpha linked polysaccharides1. Starch is a complex carbon and is the main energy storage material found in plants and some bacteria. It is a major component of food as it supplies plants with energy and carbon. Starch consists of two types of polysaccharides called amylose and amylopectin1.The properties of starch can depend on the number of alpha 1‚4 glycosidic bonds and the nature of branching. It also is the starting material for ethanol production. Ethanol production is composed of 5 general steps

MANGOSTEEN FRUIT | | | | The Mangosteen Fruit is by far the most exotic fruit in the world. It has been researched and studied so much that this site is dedicated to bring you all that information and research. | | The Mangosteen contains several classes of phytonutrient antioxidants and is the only place in nature to contain a broad spectrum of a new class of phytonutrients called Xanthones. The potent effects on human health of the Mangosteen have been observed for centuries in Southeast

disaccharides consist of two monosaccharides that are linked together. Complex Carbohydrates are also broken down into two types the oligosaccharides and the polysaccharides. The oligosaccharides are complex and consist of 3 to 10 sugars. They are rich in fiber and they take longer to digest than simple carbohydrates. The polysaccharides have a great amount of vitamins‚ minerals‚ and fiber and contain even more sugar than the oligosaccharides. Some examples of complex carbohydrates are cellobiose

Carbohydrateby Anthrone Method Carbohydrates are the important components of storage and structural materials in the plants.They exist as free sugars and polysaccharides. The basic units of carbohydrates are themonosaccharides which cannot be split by hydrolysis into more simpler sugars. The carbohy-drate content can be measured by hydrolysing the polysaccharides into simple sugars by acidhydrolysis and estimating the resultant monosaccharides. PRINCIPLE Carbohydrates are first hydrolysed into simple sugars

Why is water important for living organisms? Water is very important in all living organisms‚ it is vital for many different things. Around 70% of our body weight is due to water. The quantity is high in organs such as lungs and brain and fluids such as blood‚ lymph‚ saliva and secretions by the organs of the digestive system. First of all water is vital in the regulation of body temperature to depending on the temperature mammals will alter the amount they sweat. If they are to warm the amount

information through a process known as transformation.[2][3] Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth) and type II-R (rough) strain. The III-S strain covers itself with a polysaccharide capsule that protects it from the host’s immune system‚ resulting in the death of the host‚ while the II-R strain doesn’t have that protective capsule and is defeated by the host’s immune system. A German bacteriologist‚ Fred Neufeld‚ had discovered
