some wastes especially wastes of food industries need to be treated in order to recover some value-added products. one of these valuable products is biological pesticides. today, the most successful biological pesticides are produced by gram-positive, rod-shape bacteria, the genus bacillus that produces crystalline endotoxin proteins during spore formation. these toxins will be activated when t...

The tapioca processing industry is considered to be one of the largest food processing industrial sectors in Thailand. However, the growth of the tapioca starch industry has resulted in heavy water pollution as it generates large amount of solid waste and wastewater with high organic content. This study explores the applicability of clean technology options to improve the environmental performa...

due to the population growth and human activities in the agricultural and industrial fields, healthy and sanitary water has become scarce. due to its high contamination load, environmental harms and water discharge standards, starch producing industry is regarded as one of the industries polluting water sources which its treatment and recovery remains important. in the present study, after fabr...

The cells of filamentous fungus R. oryzae entrapped in the polyvinyl alcohol cryogel are capable of producing various extracellular hydrolytic enzymes (proteases, amylases, lipases) and are used for the treatment of complex wastewaters of food industry. Five types of media simulating the wastewater of various food enterprises were treated under batch conditions for 600 h. Fats containing mostly...

a solid – liquid – gas, multiphase reactor, called inverse fluidized bed bioreactor (ifbbr) was used in this study for the treatment of starch industry wastewater of high organic content and acidic nature. mixed culture obtained from the sludge, taken from starch industry effluent treatment plant, was used as microorganisms. experiments were carried out in an inverse fluidized bed bioreacto...

This paper presents a case study on application of photosynthetic bacteria wastewater treatment system to recover organic carbon in wastewater in the form of photosynthetic bacterial cells. In noodle production process, the wastewater was mainly produced during rice soaking and rinsing processes containing starch as its main constituent. For carbon recovery purpose, wastewater was applied to la...

Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

Screening of different adjuvants, namely, suspending agents, phagostimulants, stickers, antimicrobial agents, and UV screens to develop aqueous biopesticidal suspensions of Bacillus thuringiensis (Bt) variety kurstaki HD-1 fermented broths, specifically, nonhydrolyzed sludge, hydrolyzed sludge, starch industry wastewater, and soya (commercial medium), were investigated. The selected suspending ...
