Role of Live Microbes for Fermentation and Enhancement of Feeding Value of Wheat Straw as Animal Fodder

Nowadays, a resource terrible and technologically hungered farmhand within the developing nations of tropical zones faces intense challenges of their livestock farming and products due to tremendously and seriously increments of the human populace in this century. These challenges create this potential to feed human food security and not meet this sector's 2050 human population demand. The farmer faces the challenges of creating better value and sufficient harvests. Their livestock’s low-fine feedstuff-like crop-residues with low dietary due to shrinking grazing land shifted to farming land. Hence, our farmers want the generation that tackles this hassle through biological treatment to get without difficulty digested, nicely evolved flavor and nutritionally in shape, extra protein content in flip offers proper milk and red meat in-phrases of high-class besides capacity. This study aimed to determine the nutritional worth of wheat chaff treated biologically by bacterial and fungal Lactobacillus Casei Shirota and Aspergillus Niger strain. It also analyzed the physical and chemical structure of fermented chaff to obtain the numerical values that indicate the increments straw value and enhance feed intake of the individual livestock.

An Innovative System for Maize Cob and Wheat Chaff Harvesting: Simultaneous Grain and Residues Collection

Maize and wheat are two of the most widespread crops worldwide because of their high yield and importance for food, chemical purposes and livestock feed. Some of the residues of these crops (i.e., maize cob and wheat chaff) remain in the field after grain harvesting. In Europe, just maize cob and grain chaff could provide an annual potential biomass of 9.6 Mt and 54.8 Mt, respectively. Collecting such a biomass could be of interest for bioenergy production and could increase farmers’ income. Progress in harvest technology plays a key role in turning untapped by-products into valuable feedstocks. This article presents a study of the performance and the quality of the work of Harcob, an innovative system developed for maize cob collection. Furthermore, the feasibility of using the Harcob system to also harvest wheat chaff during wheat harvesting was also verified. The results showed that it was possible to harvest 1.72 t ha−1 and 0.67 t ha−1 of cob and chaff, respectively, without affecting the harvesting performance of the combine. The profit achievable from harvesting the corn cob was around 4%, while no significant economic benefits were observed during the harvesting of wheat chaff with the Harcob system. The use of cereal by-products for energy purposes may allow the reduction of CO2 from fossil fuel between 0.7 to 2.2 t CO2 ha−1. The Harcob system resulted suitable to harvest such different and high potential crop by-products and may represent a solution for farmers investing in the bioenergy production chain.

Optimization of the simultaneous production of cellulase and xylanase by submerged and solid-state fermentation of wheat chaff

Wheat chaff as an agricultural waste represents a cheap raw material for biotechnological processes. With its lignocellulosic composition, it is suitable for producing hydrolytic enzymes for second generation renewable fuel production technologies. The aim of this work was to optimize the process parameters (cultivation temperature 25?35?C, pH value 4?6 and cultivation time 3?7 days) of the cultivating fungi (Trichoderma reesei QM 9414) on a media based on wheat chaff by submerged and solid-state techniques, in order to enhance and compare the two types of simultaneous cellulase and xylanase production. Optimal conditions for the submerged fermentation were 29.65?C for temperature, pH 4.27 and 7 days of cultivation, while for the solid-state fermentation, the optimal conditions were 28.01?C, pH 6.00 and 7 days. The cellulolytic and xylanolytic activities of the obtained cultivation broth filtrates were 0.0535 and 0.1676 U mL-1 for the submerged fermentation, and 0.0407 and 0.1401 U mL-1 for the solid-state fermentation, respectively, and with a 26.77 and 13.39 % enhancement of enzyme activity for submerged fermentation, and a 22.96 and 42.66 % enhancement for solid-state fermentation, respectively, compared to the results obtained before optimization.
