BACKGROUND L-tryptophan is used widespread in the pharmaceutical industry. The majority of L-Trp production depends on microbial processes that produce L-tryptophan from indole and L-serine. These processes are very costly due to the costs of precursors, especially L-serine. Use of inexpensive substitutions as the L-serine source of L-tryptophan production enables us to reach a cost-effective p...

Across the world 125 to 130 million tons of sugar is produced every year. About 2/3 rd of this is produced from sugarcane and 1/3 rd from sugar beet. Sugar industry play an important role in economic growth of country but the effluent releases from the industry posses abrupt changes to water quality and cause water pollution which eventually causes health hazards. The variety of microbes presen...

One osmotolerant strain from among 44 yeast isolates was selected based on its growth abilities in media containing high concentrations of sucrose. This selected strain, named SKENNY, was identified as Meyerozyma guilliermondii by sequencing the internal transcribed spacer regions and partial D1/D2 large-subunit domains of the 26S ribosomal RNA. SK-ENNY was utilized to produce high-fructose glu...

In the current scenario due to increased input costs, commercial dairy operations are seeking reduced-cost feed alternatives to enhance productivity while reducing feed costs. The organic dairy sector has had recent unprecedented changes in their industry due to increased grain prices. Therefore, organic dairy farmers in particular are seeking lowercost energy alternatives. Sugar cane molasses,...

The present study is concerned with the production of cephalosporin C by Cephalosporium acremonium C-10. Two culture media were tested for the production of antibiotic. Among these culture media M1 containing sucrose, ammonium acetate, cornstarch, sugar cane molasses, soybean meal, calcium carbonate, calcium sulphate and methyl oleate gave optimum production of cephalosporin C. The cultural con...

The current study is an attempt to contribute for efficient and cost-effective substrates for xanthan gum production. In this context, the sugar cane molasses wastes can be used as a cheap substrate for xanthan gum production. Xanthan biopolymer production by a novel Xanthomonas campestris strain IBRC-M 10644 was optimized with statistical approaches. Based on the results ...
