BACKGROUND Pectin-rich wastes, such as citrus pulp and sugar beet pulp, are produced in considerable amounts by the juice and sugar industry and could be used as raw materials for biorefineries. One possible process in such biorefineries is the hydrolysis of these wastes and the subsequent production of ethanol. However, the ethanol-producing organism of choice, Saccharomyces cerevisiae, is not...

The recalcitrance of lignocellulose makes enzymatic hydrolysis of plant biomass for the production of second generation biofuels a major challenge. This work investigates an efficient and economic approach for the enzymatic hydrolysis of sugar beet pulp (SBP), which is a difficult to degrade, hemicellulose-rich by-product of the table sugar industry. Three fungal strains were grown on different...

the aim of this study was to evaluate the physical characteristics, chemical composition and protein fractions of sugar beet pulp produced in iran and comparing them with the tabular values of cornell net carbohydrate and protein system. a total of 39 samples of 13 different sugar factories were sampled from iran-wide. particle size distributions of samples were determined using the penn state ...

the present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by trichoderma reesei and trichoderma viride. in vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. the cultivation of t. reesei and t. viride on orange pe...

The objective of the current series of experiments was to assess the effects of dietary synchrony of OM and N supply to the rumen, achieved by altering the sequence of feeding individual ingredients and in diets with different energy sources, on the metabolism and performance of growing lambs. In Exp. 1, the in situ degradability coefficients of OM and N were determined for five feed ingredient...

A repeated 4×4 Latin square design was conducted with eight ileal cannulated castrates to examine the effect of source of starch and fiber on nutrient balance and energy metabolism. Pigs were fed on one of the four experimental diets: Control diet (C) mainly based on cooked rice; and diets P, S and W with the inclusion of either raw potato starch, sugar beet pulp or wheat bran supplementation, ...

ethanol is a clean and renewable energy source. the necessity of ethanol usage, instead of fossil fuels or mixed with them, in order to reduce environmental pollution resulted in increase of ethanol production from 50 million m-3  in 2007 to 85 million  m-3 in 2012. the present study aimed to compare the cost of bio-ethanol production from sugar beet with other agricultural crops, and also econ...
