Abstract This study reports the use of statistical mixture design as a tool for the simultaneous production of lipase, CMCase, α-amylase, and β-glucosidase by Aspergillus niger under solid-state fermentation. Wheat bran, soybean meal, cottonseed meal, and orange peel were used as substrates, either individually or combined in different formulations, to study their synergistic or antagonistic effects on production of the enzymes. The highest lipase (323 U g-1) and CMCase (10 U g-1) activities were detected after 48 h, while the maximum activities of α-amylase (18 U g-1) and β-glucosidase (15 U g-1) occurred at 72 and 96 h, respectively. Considering the substrate formulation, the ternary mixture of wheat bran (1/3), soybean meal (1/3), and cottonseed meal...

Hydrogen production from cassava processing wastewater in an anaerobic fixed bed reactor with bamboo as a support material REA
Andreani,Cristiane L.; Torres,Douglas G. B.; Schultz,Leonardo; Carvalho,Karina Q. de; Gomes,Simone D..
Attempting to associate waste treatment to the production of clean and renewable energy, this research sought to evaluate the biological production of hydrogen using wastewater from the cassava starch treatment industry, generated during the processes of extraction and purification of starch. This experiment was carried out in a continuous anaerobic reactor with a working volume of 3L, with bamboo stems as the support medium. The system was operated at a temperature of 36°C, an initial pH of 6.0 and under variations of organic load. The highest rate of hydrogen production, of 1.1 L.d-1.L-1, was obtained with application of an organic loading rate of 35 g.L-1.d-1, in terms of total sugar content and hydraulic retention time of 3h, with a prevalence of...

Selection of microorganisms for biosurfactant production using agroindustrial wastes BJM
Nitschke,Marcia; Ferraz,Cristina; Pastore,Gláucia M..
Biosurfactant production by some bacterial isolates using molasses, milk whey and cassava flour wastewater (manipueira) as substrates was evaluated and compared with the production in conventional medium. Isolates growing in manipueira medium decreased the surface tension around 42%, the highest reduction among all the substrates tested. From the eleven isolates tested, eight were able to decrease the surface tension to levels below 30 mN/m using manipueira as substrate. The isolates LB5a, LB2a, LB262, LBB and LB1a that gave surface tension about 26 mN/m were identified as Bacillus sp. Natural manipueira (high solids content) and decanted manipueira (no solids) were investigated as culture media for biosurfactant production by selected microorganisms....
