Phytochemical examination of corncob extracts led to the isolation of a new lignan identified as 7,7'-dihydroxy-3'-O-demethyl-4-methoxymatairesinol, together with seven known compounds, identified as β-sitosterol, β-sitosteryl-β-D-glucoside, 6β-hydroxy-campest-4-en-3-one, 5α,8α-epidioxyergosta-6,22-dien-3β-ol, tricin, kaempferol and p-coumaric acid. The isolated compounds were identified by one...

One of the activities carried out is to take advantage potential in village so that it can be a solution for villagers, namely use corncob waste become animal feed with economic value. The method used this activity through direct training Mesa Pau Farmers' group, socialization, processing, and utilization corncob-fermented products. aim implementing program provide medium managing Ihing village...

Hemicellulose in corncob was simultaneously degraded and oxidized into oligosaccharides, which served as a masking agent for leather tanning.

Water contamination by methylene blue (MB) is a threat to human health and aquatic biota due its toxicity, persistence, non-biodegradability. However, there little data available in the literature on removal approach from industrial effluents corncob-activated carbon. The purpose of this study was investigate adsorption aqueous solution capacities carbon were investigated batch experiments both...

Five microorganisms, namely Aspergillus niger CECT 2700, A. niger CECT 2915, A. niger CECT 2088, Aspergillus terreus CECT 2808, and Rhizopus stolonifer CECT 2344, were grown on corncob to produce cell wall polysaccharide-degrading enzymes, mainly xylanases, by solid-state fermentation (SSF). A. niger CECT 2700 produced the highest amount of xylanases of 504 ± 7 U/g dry corncob (dcc) after 3 day...

In order to determine optimal conditions for maintaining biomass quality during storage, an analysis was conducted investigate the changes in characteristics Bangkok, Thailand. The study focused on three types of biomass: corncob, woodchip, and bagasse, which are valuable renewable energy resources region. Each type divided into two separate piles: one covered with a plastic sheet other left un...

The aim of this study was to verify the viability of lignocellulosic substrates to obtain renewable energy source, through characterization of the cellulolytic complex, which was obtained by solid state fermentation using Trichoderma viride. Enzymatic activity of the cellulosic complex was measured during saccharification of substrates filter paper, eucalyptus sawdust, and corncob, and compared...

Laccase production by Pycnoporus sanguineus RP15 grown in wheat bran and corncob under solid-state fermentation was optimized by response surface methodology using a Central Composite Rotational Design. A laccase (Lacps1) was purified and characterized and the potential of the pure Lacps1 and the crude culture extract for synthetic dye decolorization was evaluated. At optimal conditions (eight ...

As a by-product generated from the processing of corn, the production in China of corncob (CC) is abundant, with up to 3.87 million tons per year. The biomass gasification industries make use of the CC residue as feedstock, but large volumes of generated corncob ash (CCA) requires daily disposal. In this study, CCA was characterized by laser particle size analyzer (LPSA), X-ray fluorescence (XR...
