Lignocellosic ethanol production is now at a stage where commercial or semi-commercial plants are coming online and, provided cost effective production can be achieved, lignocellulosic ethanol will become an important part of the world bio economy. However, challenges are still to be overcome throughout the process and particularly for the fermentation of the complex sugar mixtures resulting fr...

An epidemiological study was undertaken in a sugar cane plantation of the Sugar Company of Kwilu Ngongo in the Democratic Republic of Congo (DRC) to evaluate the incidence of the snakebites, to report the epidemiological and clinical indicators and the therapeutic practices. The plantations extend by 41 km covering about 10,000 hectares in arboreal savannahs. The method associated i) a retrospe...

A Keiki is the product of asexual propagation which naturally develop at node a flower stalk or cane. Phalaenopsis produce along middle to end nodes on stalk. Although keikis are an inefficient way propagate orchids commercial scale, it interesting study cytokinin hormone Benzyl Aminopurine (BAP) effect stimulate Two each were used in this experiment. Cytokinin (0 mg L −1 , 2 000 4 6 BAP) was o...

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...

Mild moisture stress causes sucrose to be deposited preferentially in sugarcane stalks so that sucrose yields may be improved. The rule of thumb in the industry states that a crop should be dried off for the time it would take pan evaporation to equal twice the plant available water holding capacity of the soil in which the crop is rooted (or twice TAM). Despite this useful rule farmers often d...

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...

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 ...
