“…Therefore, inoculation with L. plantarum A1 improved the N contents of the ensiled forages by accelerating the LA production and lowering the silage pH, halting the proteolytic activities [46,49]. In addition, the decline of pH and the increase in LA with increasing soybean inclusion in both uninoculated and inoculated silage treatments could be partly attributed to the enhanced microbial and enzymatic activities due to sufficient N provided by the soybean forage [23], and also the ease of degradability of soybean compared to sorghum [13,52]. Hence, the degradation of soybean forage by microbial and enzymatic activities during fermentation added fermentable substrates into the soybean incorporated treatments, resulting in higher LA production, which ultimately declined the silages' pH.…”

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.
