background and objectives: the essential amino acid l-tryptophan can be produced by a condensation reaction between indole and l-serine, catalyzed by b. subtilis with tryptophan synthase activity. application of the tryptophan is widespread in the biotechnology domain and is sometimes added to feed products as a food fortifier. materials and methods: the optimum concentration of the iranian can...

Efficient lactic acid production from cane sugar molasses by Lactobacillus delbrueckii mutant Uc-3 in batch fermentation process is demonstrated. Lactic acid fermentation using molasses was not significantly affected by yeast extract concentrations. The final lactic acid concentration increased with increases of molasses sugar concentrations up to 190 g/liter. The maximum lactic acid concentrat...

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 ...

BACKGROUND Cane molasses, an important residue of the sugar industry, have the potential as a cost-effective carbon source that could serve as nutrients for industrial enzyme-producing microorganisms, especially filamentous fungi. However, the enzyme mixtures produced in such a complex medium are poorly characterized. In this study, the secretome of Trichoderma reesei grown on a cane molasses m...

In 1941 Wulzen and Bahrs (1) reported a characteristic muscular stiffness at the wrist among guinea pigs on a skim milk diet, which progressed in intensity over a period of months. Autopsies of deficient animals revealed extensive calcification throughout the muscles and internal organs. Raw cream fed by mouth was found to alleviate the wrist stiffness within a few days, although disappearance ...

objective(s): sugar cane molasses is a commonly used ingredient in several food products. contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. however, little evidence exists that examines the effects of molasses on the different physiological systems. this study investigated the effects of sugar cane molasses on various physiological syste...

Stillage or vinasse, which is a byproduct of ethanol production, is produced from the fermentation of molasses and is used as a source of potassium on cane fields at Simunye-Royal Swaziland Sugar Corporation. Due concern regarding its high salt content and Chemical Oxygen Demand (COD), a trial was established on an S set soil (Mayo form) to study the effect of increasing levels of concentrated ...

Fermentations utilizing strains of Zymomonas mobilis, in place of the traditional yeasts, have been proposed due their ethanol yields being close to theoretical. Ethanol production from sugar cane molasses was analyzed under different culture conditions using Z. mobilis in batch fermentation. The total reducing sugars (TRS) concentrations in the molasses, temperature, agitation and culture time...

The treatments consisted of chopping sugar cane stalk coarsely (10 to 20 mm particle size) or finely (less than 5 mm). The chopped cane stalk was mixed with chopped cane tops ( 40 to 50 mm particle size) in the ratio 75: 25. A solution of urea/molasses (200 g urea/kg solution) was added to the cane at the rate of 50 g/kg of fresh cane. The animals also received 600 g/d cotton seed meal and 100 ...
