Anion-exchange DEAE-cellulose Diethylaminoethyl-cellulose chro-matography was performed for further purification of the L-gluta-minase enzyme obtained from the previous ammonium sulfate glutaminwse Kashyap P, et al.

Therefore, salt-tolerant glutaminase may show potentially important roles in food fermentation process that need high-salt environments. Accounting essays Architecture essays Business essays Coursework Economics essays Education essays Engineering essays English language essays English literature essays.

One of the furthermost significant roles of glutaminase is found in the axonal thesiis of neurons in the central nervous system.

L-Glutaminase was found to be encouraged by L-glutamine. Various fermentation parameters for the production of L-glutaminase in solid state fermentation Organism Solid Substrate pH Medium Incubation temperature oC Reference Vibrio costicola Polystyrene beads 7 35 Prabhu and Chandrasekaran, et al.

There has been varied difference in the molecular weight of L-glutaminases from diverse sources, which could series between 40 and kDa. Table 2 shows the various bacteria, yeast and fungus used for the production of the L-glutaminase. HungundIsolation and characterization of L- Glutaminase Enzyme A project on Isolation and Characterization of L- Glutaminase Enzyme Producing Actinomycetes from Mangrove Ecosystem Dissertation submitted to the Isolation and identification of actinomycetes for Isolation and identification of actinomycetes for production of novel extracellular glutaminase free L-asparaginase.


We are completely closed on Tuesday 1st January. The major advantage of using microorganisms for the production of L-glutaminase is the economical bulk production capacity and also microbes are easy to manipulate to obtain enzymes of desired characteristics Sarada, et al. The authors confirmed bacterial strains, yeast strains and fungal strains for L-glutaminase activity.

The result will be a substantial reduction of the reverse transcriptase activity in human serum, which helps to inhibit HIV replication in infected cells. Several reports used the microbial L-glutaminases either immobilized L-glutaminase or whole cells of L-glutaminase producing microbes in food flavoring for continuous conversion of glutamine to glutamate in food preparations Hamada, et al. It is usually achieved by filtration, centrifugation, and precipitation, and also by various chromatographic procedures such as ion exchange, gel permeation, and attraction chromatography.

Over a insufficient decades, considerable research has been undertaken with the microbial production of extracellular L-glutaminase.

Glutaminase I was stable and exhibited about 1. Such an application is proposed for the treatment of human immunodeficiency virus HIV by administrating L-glutaminase from Pseudomonas sp.

Interesting fact in SSF which added renewed notice from researchers in assessment of its economic and engineering advantages are cheap agro-industrial residues Khandeparkar, et al. It can be used to analyze L-glutamine and glutamate the levels in the body fluids Sarada, et al. For the production of L-glutaminase in ssf several agro industrial materials were used as solid provision. Many substances and heavy metals inhibit the enzyme, L-glutaminase activity Sarada, et al. KLM9 Nathiya, et al.

L-Glutaminase is considered an important agent as flavor enhancers in the food industry, due to its involvement in the synthesis of L-glutamic acid, the main compound is responsible for the delicious taste or flavor and theais of many fermented products like soy sauce, miso ,sufu and popular Sabuhtesis al.

Acetone and enzyme both with glucose and without glucose was retained for a day and future centrifuged Anubrata Paul, et al. The fractions were collected and examined for enzyme activity and protein content, Elshafei, et al.

Submerged fermentation smf involves of the cultivation of microbial cells in liquid media under measured conditions, in large vessels called bioreactors, for the production of required metabolites.

Effect of several carbon sources Glucose, Fructose, Galactose, Lactose, Maltose, Xylose, Sucrose, Mannitolmixtures of carbon sources and inorganic nitrogen Ammonium sulphate, ammonium nitrate and ammonium chloride sources at diverse concentrations and organic nitrogen sources peptone, corn steep liquor beef extract, yeast extract and soya bean meal at 0.

Cells entrapped in either sodium alginate or agar are widely used Kashyap, et al. Still, there is sufficiently of room for examination on glutaminases including the isolation of salt-and thermo-tolerant enzymes, which would meaningfully enhance their applications in the food industry.
