[What is Ginseng]

In terms of modern scientific research, ginseng is known to be an adaptogen. Adaptogens are substances that assist the body to restore itself to health and work without side effects even if the recommended dose is widely exceeded.

Ginseng due to its adaptogens effects is widely used to lower cholesterol, increase energy and endurance, reduce fatique and effects of stress and prevent infections.

Ginseng is one of the most effective antiaging supplements. It can alleviate some major effects of aging, such as degeneration of the blood system, and increase mental and physical capacity.

Other important benefits of ginseng is its support in cancer treatment and its effects on sports performance.

Culture: The propagation of microorganisms using various media ,Culture media Used to grow bacteria
Can be used to: Enrich the numbers of bacteria
Select for certain bacteria and suppress others Differentiate among different kinds of bacteria ,Culture and Medium Culture is the term given to microorganisms that are cultivated in the lab for the purpose of identifying and studying them.
Medium is the term given to the combination of ingredients that will support the growth and cultivation of microorganisms by providing all the essential nutrients required for the growth (that is, multiplication) in order to cultivate these microorganisms in large numbers to study them. ,Specific Media Defined media are media composed of pure ingredients in carefully measured concentrations dissolved in double distilled water i.e., the exact chemical composition of the medium is known. Typically, they contain a simple sugar as the carbon and energy source, an inorganic nitrogen source, various mineral salts and if necessary growth factors (purified amino acids, vitamins, purines and pyrimidines
,Need for Culture Media It is usually essential to obtain a culture by grwoing the organism in an artificial medium.
If more than one species or type of organism are present each requires to be carefully separated or isolated in pure culture. Several organism need the determination of Antibiotic sensitivity pattern for optimal antibiotic selection ,Basic requirements of culture media Nutrients – Energy source – Carbon source – Nitrogen source Mineral salts – Sulphate, phosphates, chlorides & carbonates of K, Mg & Ca. A suitable pH – 7.2 – 7.4 Accessory growth factors – Tryptophan for Salmonella typhi – X & V factors for H. influenzae
