Anim Sci J 2024; 95:e13937. [PMID: 38500367 DOI: 10.1111/asj.13937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 12/28/2023] [Accepted: 01/29/2024] [Indexed: 03/20/2024]
Abstract
This experiment aimed to study the degradation characteristics of bagasse after three fermentation treatments in beef cattle. Bagasse 1 was treated with 0.3% lactic acid bacteria (w/w). Bagasse 2 was treated with 0.3% mixed strains (Saccharomyces cerevisiae, Aspergillus niger, Aspergillus oryzae, and lactic acid bacteria at 2:1:1:1). Bagasse 3 was treated with 0.1% cellulase and 0.1% xylanase in addition to 0.3% mixed strains of bagasse 2. The dry matter (DM), crude ash (ASH), crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in the bagasses were determined. Compared to the control bagasse (without the strain and enzyme treatments), three fermented bagasses showed higher DM after 4 h fermentation. The CP and ASH contents in fermented bagasse 3 were the highest, while the contents of NDF and ADF in fermented bagasse 3 were the lowest among all the groups. The effective degradability of DM, CP, NDF, and ADF was highest in fermented bagasse 3 among the evaluated bagasse feed, followed by fermented bagasse 2 > fermented bagasse 1 > bagasse. Overall, fermented bagasse 3 was better than the control and other treated bagasses, thus fermented bagasse 3 is a hopeful source for ruminant diet of beef cattle.

Abstract
Lignocellulosic biorefining for producing biofuels poses technical challenges. It is usually conducted over a long time using heat, making it energy intensive. In this study, we lowered the energy consumption of this process through an optimized enzyme and pretreatment strategy. First, the dominant mutant M137E/N269G of Bispora sp. MEY-1XYL10C_ΔN was obtained by directed evolution with highcatalytic efficiency (970 mL/s∙mg)and specific activity (2090 U/mg)at 37 °C, and thermostability was improved (T50 increased by5 °C). After pretreatment with seawater immersionfollowing steam explosion,bagasse was co-treated with cellulase and M137E/N269G under mild conditions (37 °C), the resulting highest yield of fermentable sugars reached 219 µmol/g of bagasse,46% higher than that of the non-seawater treatment group, with the highest degree of synergy of 2.0. Pretreatment with seawater following steam explosion and synergistic hydrolysis through high activity xylanase and cellulase helped to achieve low energy degradation of lignocellulosic biomass.

BIORESOURCE TECHNOLOGY 2021; 337:125392. [PMID: 34130232 DOI: 10.1016/j.biortech.2021.125392] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/04/2021] [Accepted: 06/05/2021] [Indexed: 06/12/2023]
Abstract
To improve the utilization efficiency of corn stover , steam explosion pretreatment and cellulase/lactic acid bacteria-assisted ensilage storage were conducted in sequence, mainly focusing on morphological structure, lignocellulose fraction, cellulose accessibility and degradation profile. The results showed that there was a synergistic effect of steam explosion and ensilage storage, where hemicellulose of corn stover was partly degraded during steam explosion processing (70%) or ensilage storage (20-40%). Meanwhile, its morphological structure was apparently broken, increasing cellulose accessibility (2.44, 2.83, 4.08-4.33 mg/g), where enzyme YDL and inoculant QZB were the two most effective additives. Furthermore, rumen effective degradability of corn stover (39.25%, 48.33%, 52.57-54.07%) were increased along with greater rapid degradation fraction (0, 1.67%, 9.16-11.62%) and degradation rate of slow degradation fraction (0.020, 0.034, 0.039-0.048 h-1) . In conclusions, it is suggested that treating corn stover with steam explosion processing and ensilage storage is a feasible way to improve its utilization efficiency.
