Production of reducing sugar by hydrolysis of corncob material with Streptomyces sp. cellulase and ethanol fermentation of cellulosic hydrolysate was investigated. Cultures of Streptomyces sp. T3-1 improved reducing sugar yields with the production of CMCase, Avicelase and β-glucosidase activity of 3.8, 3.9 and 3.8 IU/ml, respectively. CMCase, Avicelase, and βglucosidase produced by the Strepto...

To obtain high concentration of ethanol from cellulose, corncob was pretreated with acid and alkali to remove non-cellulose components, and then subjected to simultaneous saccharification and fermentation (SSF). An ethanol concentration as high as 69.2 g/L was achieved with 19% dry matter (DM) using batch SSF, resulting in an 81.2% overall ethanol yield. A fed-batch process using a high solid c...

This work presents an integrated and multi-step approach for the recovery and/or application of the lignocellulosic fractions from corncob in the production of high value added compounds as xylo-oligosaccharides, enzymes, fermentable sugars, and lignin in terms of biorefinery concept. For that, liquid hot water followed by enzymatic hydrolysis were used. Liquid hot water was performed using dif...

Two newly developed Bacillus sphaericus larvicidal formulations, VectoLex CG® (corncob granules) and VectoLex WDG® (water dispersible granules), were tested against Culex quinquefasciatus larvae in 4 highly polluted breeding sites in Thailand. VectoLex CG, applies at rates of 0.5-2 g/m2, gave satisfactory to complete control of late-instar larvae and pupae for up to 4 wk after treatment. The Ve...

Estradiol can modulate neural activity and behavior via both genomic and nongenomic mechanisms. Environmental cues have a major impact on the relative importance of these signaling pathways with significant consequences for behavior. First we consider how photoperiod modulates nongenomic estrogen signaling on behavior. Intriguingly, short days permit rapid effects of estrogens on aggression in ...

Wastewater with a low carbon/nitrogen (C/N) ratio is widespread and difficult to treat. The addition of an external carbon source effective method for treating such wastewater. Therefore, we aimed prepare self-releasing biofilm carrier using agricultural waste (corncobs), polyvinyl alcohol, sponge iron in various ratios provide that would facilitate denitrification, providing optimal environmen...

Adsorption of zinc (Zn), cadmium (Cd), and nickel (Ni) from aqueous solutions by corncob (CC) granular activated carbon prepared (GACC) were carried out. Synthetic Cd, Ni, Zn at 3.0 ppm each used to perform the adsorption process. A batch pattern was determine kinetics as well isotherm parameters. The obtained results using either both CC GACC separately found be matched with Langmuir model. Fu...
