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 of response surface me...

In Brazil the sugar ethanol industry has had strong growth in the last 10 years, sometimes due to the growing sugar exportation, sometimes due to the alcohol production for automobile fuel and for exportation. Despite the growing mechanization of the raw material harvest (sugar cane), the manual work still persists. The development of this article was based in the application of the OCRA Method...

Dextran is one of the by-products of sour-storage rot of sugar cane (Egan, 1971). The presence of dextran in cane juice entering the mill has many deleterious effects on raw sugar processing and quality (Foster, 1969a,b; Henderson, 1971; Foster and Wright, 1969; Leonard and Richards, 1969). Hence, the removal of the polysaccharide from juice may alleviate these effects. Physico-chemical methods...

at the present time 33 sugar beet and 7 sugar cane industrial units are active in the country. in 2004, the national sugar production was about 1192 thousand tons, that 55 percent of it was produced from the sugar beet and the rest from the sugar cane. in this investigation the status of sugar beet root and sugar production during last 4 years is discussed. the theoretical capacity of 33 sugar ...

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 ...

Industrial-scale production of biopolymers is restricted by its elevated production costs in comparison with those associated with synthetic (no-biodegradable and no-biocompatible) polymers. In this study we tested for the first time two low-cost carbon substrates (i.e. carob pulp and fique juice) for lab-scale production of polyhydroxyalkanoate (PHA) with Bacillus megaterium. PHA detection and...

Recovery of sugars from cane molasses (i.e. the by-product of sugar industries) is of great interest to industry and academia. The prerequisite for refning cane molasses is removal of pigments and suspended solids present in the molasses. In this work, the utilization of membrane separation for clarifcation and decoloration of cane molasses has been examined. Three oper...
