Media For Industrial Fermentation Impact Factor

Micro-organisms used for fermentation process grow on or in growth medium which satisfies the nutritional needs of microbes. Complete analysis is required to be done to determine the foremost favourable medium for the expansion of the microbe used for fermentation. Formulating medium at lab scale are often done by adding main ingredients like water, carbon source, nitrogen source, minerals and other supplements in pure form and in required quantities is extremely easy which supports the expansion of the microbe whereas, an equivalent might not support the satisfactory growth of an equivalent organism at industrial level. Following criteria got to be satisfied for the fabric to be treated as medium at industrial level. • It should give maximum yield of product. • It should give minimum yield of undesired product. • It should be consistently available throughout the year. • It should be cheap. Generally carbohydrates are used as “carbon sources” for fermentations at lab level. But, at industrial level cane molasses, corn steep liquor, sugar beet juice which are inexpensive sources are utilised. On contrary, some sensitive fermentation makes use of glucose, sucrose and other carbohydrates in their pure form which ensures the purity and quality of the ultimate product. Sometimes starch is going to be added to the medium for the precise production of amylases. At lab level, peptone or tryptone or beef extract which may be a partially digested hydrolysate, which is utilised in synthesis of proteins, components of nucleic acids and other essential cellular components. But at industrial level it's supplemented with soy meal or ammonia or nitrate salts to supplement the nitrogen source. Other elements include growth factors, vitamins, anti-foaming agents, precursors, inducers chelating agents, trace elements like Fe, Cu, Mn, Mo and Co, are added to the fermentation medium. Where growth factors, vitamins, precursors, inducers and trace elements directly supports the expansion of microbe and anti-foaming agents are added to stop the froth formation, just in case of presence of upper concentrations of metal ions which isn't preferable chelating agents are added. The impact factor (IF) or journal impact factor (JIF) of a tutorial journal is a scientometric index that reflects the yearly average number of citations that articles published within the last two years during a given journal received. It's frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factors are often deemed to be more important than those with lower ones.
