“…The pretreated samples were further digested/hydrolyzed for 72 hours and then cooled to room temperature. 38 AD design for methane production Eight 500 mL serum bottles were numbered R1-R8 and the pretreated wheat straw mixtures numbered 1-7 were transferred into the serum bottles numbered R1-R7, respectively. The R6 group was pretreated with CaO 2 alone, the R7 group was pretreated with cellulase alone, and in the R8 group, the wheat straw was directly fermented without additives to produce CH 4 as a control experiment.…”

“…Similar results have been reported in previous studies. For example, Xu et al (2020) reported that cellulase with Lactobacillus plantarum A1 performed well in fiber degradation during the coensiling of corn stalk and potato pulp. In addition, an improvement in the silage quality of mulberry leaves was observed with the application of cellulase and Lactobacillus casei LC (He et al 2019).…”

Effects of cellulase addition were assessed relative to the co-ensiling performance of air-dried corn stover (DCS) and cabbage waste (CW). The DCS and CW mixtures were co-ensiled with 0 to 0.3% of cellulase addition, and changes in composition, intermediates, and biological activity were characterized. The results showed that the addition of cellulase enhanced the decomposition of cellulose and hemicellulose by 2.51 to 6.93% and 3.41%, based on different dosages and compared with the control. Thus, the content of water-soluble carbohydrates increased. The acid content also increased from 5.8% for the control to the range 5.16 to 8.51% for the samples containing cellulase. Moreover, there was a shift from homolactic to heterolactic fermentation with prolonged ensiling time, coupled with the dominant lactic acid bacteria shifting from Paralactobacillus and Lactobacillus to more of Lactobacillus. Thus, the addition of cellulase improved the relative abundance of Lactobacillus. An assessment of fermentation quality, therefore, suggested that cellulase addition can improve the silage quality of DCS/CW during co-ensiling.

“…The efficiency of L. plantarum A1 in improving the fermentation quality and lignocellulose degradation, as well as ferulic acid production of different biomass have previously been reported [12,14,22,32]. However, despite the higher cellulosic content of sorghum, and its ensiling potential as well as its potential for biofuel production, there is no report from any study on inoculating whole crop sorghum biomass with any feruloyl-esterase producing lactobacillus during ensiling.…”

Availability of feedstock is one of the uncertainties impeding cellulosic biofuel production, and conservation of whole crop biomass as silage is a promising method to ensure year-round feedstock availability for biofuel production. This study investigated lignocellulose degradation and subsequent enzymatic hydrolysis of a 90-d sorghum silage incorporated with soybean and inoculated with Lactobacillus plantarum A1 in a three (0, 25, and 50%; soybean inclusions) by two (uninoculated and inoculated) factorial experiment. The results revealed that L. plantarum A1 inoculated silages had improved fermentation characteristics. The silages’ total N and non-fiber carbohydrate increased with L. plantarum A1 and soybean inclusion (p < 0.05). Inoculation also increased the residual water-soluble carbohydrate by 33.9% (p < 0.05). Inoculation and soybean inclusion significantly hydrolyzed the biomass’ lignocellulose, altered its morphology and microstructural matrix, increased production of ferulic acid and reduced the biomass crystallinity by 15.60% (p < 0.05). L. plantarum A1 inoculation × soybean inclusion improved glucose yield and cellulose conversion during enzymatic saccharification compared to uninoculated treatments. Therefore, incorporating soybean into sorghum silage with L. plantarum A1 inoculation enhanced fermentation quality, lignocellulose degradation and enzymatic saccharification which could serve as a sure way for sustainable year-round feedstock supply for enhanced biofuel production.
