AbstractThe abundant availability of solid agroindustrial waste, sugarcane bagasse from sugar mills and juice extraction units, can bepotentially beneficial for the production of fermentation based biochemicals, paper boards and power. However, its role incausing bagassosis, an acute respiratory disease among the personnel handling large dry deposits has also been detected. Disposal of liquid waste whey from dairy industries poses a formidable threat to the aquatic ecosystem due to high BOD and ...

The utilization of agro-industrial waste as a potential substrate for producing enzymes may serve a dual purpose of reducing the environmental pollution along with producing a high value commercial product. Twelve different agro-industrial wastes were evaluated for extracellular BGL (β-glucosidase) production by a mutant of Bacillus subtilis on solid state fermentations (SSF). The Citrus sinensis bagasse was found to be the most suitable substrate with highest BGL titer (35 U/gds). Optimum ...

The aim of present study was the effective utilization of waste apple for high yield of ethanol using immobilized cells of Saccharomyces cerevisiae S-3S through fed-batch fermentation. Low cost biomaterial was also developed for immobilization. Immobilization was carried out on different inert supports (agar-agar, k-carrageenan, Ca-alginate, sugar cane bagasse and apple bagasse). The results revealed that immobilized cells of S. cerevisiae S-3S gave high yield of ethanol as compared to free c...

In this study, the flocculating properties of different cactus juice preparations were assessed using synthetic and real industrial and leachate wastewaters. It was found that the crude CJ had a flocculating activity (FA) of 89 ± 2.2% which is significantly higher than that of a powdery sample derived from a 60°C oven-dried CJ sample and which was about 37.8 ± 2.5%. Interestingly, both crude and dried samples showed the ability to flocculate kaolin suspensions within a wide ...

Citrus is one of the most important fruit tree crops worldwide, with respect to both total production and economic value. About 80% of the world production is destined to the fresh market, the remaining is processed to obtain various products (juices, jams, etc.). Citrus processing residues account for about 50-60% of processed fruits; their huge amounts and peculiar characteristics need a correct management that imply cost for producers and processors. If not well managed, they can represent an...
