Summary: This study investigates different pretreatment techniques for releasing fermentable reducing sugars from sugarcane bagasse and corn cobs. The alkaline pretreatment facilitated lignin removal and expedited enzymatic hydrolysis. Scanning electron micrographs and Fourier transform infrared spectra confirmed structural deformations induced by the pretreatment processes. The observations suggest that thermotolerant in-house enzymes show great potential in the saccharification of lignocelluloses within a short span of time.

Summary: A new process utilizing corncobs as a substrate for ethanol and xylitol production was presented. Acid hydrolysis of corncobs resulted in a hemicellulosic hydrolysate rich in xylose sugars, which was used for xylitol production. The remaining cellulignin portion was used for ethanol production. This process demonstrates the potential of corncobs as a carbon source for biomolecules production.

Summary: This study developed a supercritical CO2/ethanol/water ternary green system for the simultaneous production of high antioxidant activity lignin and furfural from corn cobs. The results showed that high CO2 concentration increased the permeability of ethanol to corn cobs and promoted the degradation of lignin, leading to increased lignin and furfural yields. This system also enhanced the antioxidant properties of the prepared lignin fractions.

Summary: This study describes the synthesis and utilization of Fe3O4@date seeds powder as an adsorbent for removing methylene blue from water. The Fe3O4 nanoparticles were grown on date seeds powder using a simple co-precipitation method. The prepared bio-adsorbent showed different chemical functional groups on its surface. The study demonstrated that the bio-adsorbent had a monolayer adsorption capacity of 76.652 mg g(-1) at 27 degrees C and followed the Freundlich isotherm and pseudo second order kinetic model. The adsorption process was found to be dominated by electrostatic interactions between the functional groups on the bio-adsorbent surface and the dye, with intraparticle diffusion as the rate determining step.

Summary: A novel strategy using a commercial Pd/C catalyst was proposed to produce monophenolic compounds from fermented corn stover. By controlling the reaction temperature, the highest monomer yield of 28.5 wt% was achieved at 220 degrees C, compared to 22.8 wt% for pristine corn stover. The enhanced monophenol yield was attributed to higher lignin content and lower recalcitrance in the fermented stover. The results demonstrated a potential avenue for the valorization of lignin through reductive catalytic fractionation of agricultural waste.

Summary: This study focuses on converting waste agricultural biomass to bioethanol through enzymatic hydrolysis and saccharification. Cellulase from Aspergillus niger was immobilized in Fe3O4/GO/CS nanocomposites to enhance its stability and efficiency. The immobilized cellulase exhibited high thermal stability and retained activity even after multiple cycles. Wheat bran and rice bran were pretreated and enzymatically hydrolyzed to obtain glucose, which was then fermented to produce ethanol. The study demonstrates the potential of utilizing lignocellulosic biomass for bioethanol production.

Summary: In this study, torrefied wheat straw and oat hulls were combined with kaolinite and chitosan to obtain pelletized adsorbent materials. The composites were compared to spent coffee grounds as a reference biomass system. IR and C-13 NMR spectroscopy were used for structural characterization, and a cationic dye probe was employed to evaluate the adsorption properties. The results showed that crosslinking notably reduced the adsorption capacity for torrefied biomass composites, while greater uptake occurred for the spent coffee grounds composites. A cost-benefit analysis indicated that the torrefied wheat straw composites are competitive adsorbents per dollar material cost compared to the spent coffee grounds composites. Pelletized adsorbent technology with torrefied biomass offers lower chemical input costs and sustainability.

Summary: High production costs of microbial lipids can be reduced by using available and cheap lignocellulosic biomass. This study found that C:N ratios below 25 stimulated fungus growth, while ratios above 50 led to lipid accumulation. Among the inhibitors from lignocellulosic biomass, phenolics were found to be the most toxic.

Summary: In this research, the adsorption mechanisms of CO2 onto Malaysian coals were investigated, and it was found that the dry S1 coal showed the highest CO2 adsorption capacity. The results suggested that CO2 adsorption onto coal matrix is favorable, spontaneous, and the adsorbed CO2 molecules accumulate more onto coal matrix. These findings have significant implications for a more accurate measurement of CO2 injection into Malaysian coalbed seams.
