The suitabilities of major agricultural residues were assessed as papermaking feedstocks. All the examined agricultural residues were assumed as potential candidates for substituting hardwood fibers in mixed pulp blends from a fiber morphological perspective. Wheat, barley, rice, rapeseed, maize, sunflower, sugarcane bagasse, coconut husk, and two genotypes of miscanthus grass underwent identical maceration. The fiber length, fiber width, cell wall thickness, and lumen diameter were measured to calculate the slenderness ratio, flexibility coefficient, and Runkel ratio. The average fiber length ranged from 0.50 mm ± 0.32 mm (MG-S-02-V) to 1.15 mm mm ± 0.58 mm (sugarcane bagasse). The fiber width ranged from 10.77 μm ± 3.28 μm (rice straw) to 22.99 mm ± 5.20 mm (sunflower stalk). The lumen diameter ranged from 4.52 μm ± 2.52 μm (rice straw) to 13.23 μm ± 4.87 μm (sunflower stalk). The cell wall thickness ranged from 3.02 μm ± 0.95 μm (rice straw) to 4.80 μm ± 1.48 μm (sunflower stalk). The slenderness ratio, flexibility coefficient, and Runkel ratio values ranged between 28.08 to 58.11, 37.97 to 60.8, and 0.62 to 1.68, respectively. Wheat, maize, rapeseed, sugarcane bagasse, and coconut husk were found to be appropriate residue sources for papermaking feedstocks.

Potential Use

In Egypt, animals suffer from under feeding and mal-nutrition due to the shortage of local produced feed which are not sufficient to cover the nutritional requirements of animals. The annually amount produced of agro-by¬products in Egypt are around 2.5 million ton of rice straw and one million ton of sugarcane bagasse. These wastes are usually burned causing environmental pollution. The potential use of these wastes in ruminant ration will participate in reducing the shortage of feedstuffs and subsequently increase milk and meat production in Egypt. Gas measuring technique has been widely used for evaluation of nutritive value particularly to estimate agro-industry by-products, different feed classes and energy value of straws. Therefore, the main objective of this study was to assess the nutritive value of rice straw, date stone, sugarcane bagasse and berseem hay using the in vitro gas production technique.

Organosolv Lignin

Organosolv lignins were extracted from corn stover, wheat, rice straw, reed straw, and sugarcane bagasse using a mixture of acetic and formic acids, at relatively low temperature and atmospheric pressure. Lignin content, residual carbohydrates, ash levels, proteins, and molecular weights were determined in each extracted lignin. The lignin content of all samples was relatively high, confirming the performance of the pretreatment process. The low molecular weights were in a narrow range, in accordance with the organosolv lignin molar masses. However, some differences between studied lignins were highlighted, in particular in rice straw lignin, which contained the highest silica, calcium, and nitrogen contents. Nuclear magnetic resonance spectroscopies (31P and semi-quantitative Heteronuclear Single Quantum Correlation) underlined the structural similarities and differences between these organosolv lignins. Corn stover and sugarcane bagasse lignins were rich in non-methoxylated (H-Unit) or mono-methoxylated (G-Unit) phenolic units, making them the best promising candidates for production of phenolic resins. Wheat straw lignin was richer in aliphatic OH than in phenolic OH. This is an advantage for use as polyol substitute in polyurethane synthesis. Reed straw lignin was less specific, with a balanced content of OH groups. However, it contained a high concentration of β-O-4 linkages, which is favorable for depolymerization.

AbstractObjective: Cost-effective production of industrially important enzymes is a key for their successful utilization on large scale. Present study was conducted to appraise Pleurotus sapidus WC 529 potential to produce oxidative (lignin peroxidase, manganese peroxidase, laccase) and hydrolytic (endoglucanase, exoglucanase and β-glucosidase) enzymes, grown on wheat straw, corn cobs, corn stover, rice straw, banana stalk and sugarcane bagasse in solid state fermentation (SSF) process. The crude extract thus produced was used for the delignification of various agro-industrial residues.Methods: Different agricultural wastes were assessed for lignocellulolytic enzymes production. The process parameters were optimized through response surface methodology (RSM) with central composite design (CCD) for maximum enzyme production.Results: P. sapidus secreted lower levels of hydrolytic enzymes but expressed high laccase, MnP and LiP activities in SSF (228.25, 153.45 and 59.20 UmL-1 respectively) of banana stalk. The optimal conditions for yielding highest enzyme activities were: initial pH, 4; temperature, 35°C; moisture level, 60%; inoculum size, 4 mL, and incubation time, 120 h. The enzyme extract removed 56.54, 51.08, 65.81 and 57.4% lignin from rice straw, sugarcane bagasse, corn cobs and wheat straw, respectively, after 48 h at 35°C.Conclusion: High ligninolytic activities were obtained in SSF of banana stalk by P. sapidus. The enzyme production was considerably improved by optimization through RSM. The results suggest that lignocellulolytic enzymes could be produced using cost-effective carbon sources and implicated to digest lignocellulosic biomass.

Second Generation Ethanol

Ethanol production from renewable sources, such as lignocellulosic materials, is already underway in several countries. The interest in the technology stems from concerns about global warming and the environmental impacts of solid waste disposal. Moreover, the conversion of agro-industrial wastes into ethanol is a value-adding strategy. This study aimed to evaluate the physicochemical characteristics of three lignocellulosic materials— rice straw bran, sugarcane bagasse, and corn peel bran—and determine, on the basis of these analyses, their suitability as feedstocks for second-generation ethanol production. Physicochemical characterization included the determination of particle size, moisture, ash, total solids, water activity, crude fat, protein, total extractives, soluble and insoluble lignin, holocellulose, cellulose, hemicellulose, and total carbohydrates. Rice straw bran is composed of 38.33% cellulose and 19.73% hemicellulose, sugarcane bagasse is composed of 27.09% cellulose and 5.61% hemicellulose, and corn peel bran is composed of 55.75% cellulose and 12.93% hemicellulose. The characterization showed the high concentration of cellulose in the residue of the corn peel bran. The results indicate that the three biomasses are suitable raw materials for biofuel production.
