“…The contents of water-soluble carbohydrates (WSC) was determined by anthrone method ( Murphy, 1958 ). The hemicellulose (HC) content was calculated by subtracting ADF from NDF, cellulose (CEL) content was the difference between ADF and ADL, and the holocellulose (HoC) content was the sum of HC and CEL ( Ren et al, 2015 ). In addition, the biological degradation potential (BDP) was calculated by reference to Agneessens et al (2015) using HoC divided by ADL.…”

In the current study, we assessed the effects of antibacterial peptide-producing Bacillus subtilis (BS), gallic acid (GA) and cellulase (CL) on the fermentation quality and bacterial community of various varieties of whole-plant corn silage. Three different varieties of whole-plant corn (Yuqing386, Enxiai298, and Nonghe35) were treated with 0.02% BS (fresh material basis), 0.2% GA (fresh material basis) and 0.02% CL (fresh material basis), after which 45 days of anaerobic fermentation were conducted. With the exception of its low dry matter content, the results showed that Yuqing386’s crude protein, water-soluble carbohydrate, and lactic acid contents were significantly higher than those of the other two corn varieties. However, its acid detergent fiber and cellulose contents were significantly lower than those of the other two corn varieties. Among the three corn variety silages, Yuqing386 had the highest relative abundance of Lactobacillus at the genus level and the biggest relative abundance of Firmicutes at the phylum level. In addition, the three additives markedly enhanced the quantity of dry matter and crude protein as compared to the control group. The application of GA considerably decreased the level of neutral detergent fiber while significantly increasing the content of lactic acid and water-soluble carbohydrates. Even though all additives enhanced the structure of the bacterial community following silage, the GA group experienced the greatest enhancement. On a phylum and genus level, the GA group contains the highest relative abundance of Firmicutes and Lactobacillus, respectively. Overall, of the three corn varieties, Yuqing386 provides the best silage qualities. GA has the biggest impact among the additions employed in this experiment to enhance the nutritional preservation and fermentation quality of whole-plant corn silage.

“…China is an agricultural country with abundant crop residues, with up to 320 million metric tonnes of corn (Zea mays L.) produced in 2016, which is expected to climb further in the following years (11). Corn stover represents a substantial source of lignocellulosic biomass and is the prevailing material producing bioenergy because of abundant cellulose and hemicellulose (12).…”

“…As a result, the free sugars in air-dried corn stover are not readily available, as the moisture is almost entirely evaporated during wilting and field air drying, which limits silage due to low water-soluble carbohydrate and high lignocellulosic contents (14). To overcome this limitation, addition of vegetable wastes as a source of water-soluble carbohydrates and moisture to initiate fermentation has been used to complement bulk air-dried corn stover on the basis of physical structure, nutrient and moisture contents (11). Nevertheless, the lignified nature and associated recalcitrance of air-dried corn stover, in combination with both insufficient numbers of epiphytic microflora and low moisture or water-soluble carbohydrate content, could result in a failure of the start-up of silage fermentation, or at least a delay in the initial pH drop.…”

SUMMARYA mixture of air-dried corn stover and cabbage waste was ensiled to preserve lignocellulosic biomass for use as biofuel. Furthermore, the effects of different fresh mass fractions (0.3 and 0.6 %) of formic or acetic acid on the mixed silage quality were evaluated to guarantee its quality. The application of formic or acetic acid prior to mixing the silage led to higher water-soluble carbohydrate fractions than the negative control, indicating that both acids contributed to preservation of water-soluble carbohydrates during storage for 170 days. The dry matter content was also increased after storage from 90 to 170 days. It was found that the content of neutral and acid detergent fibre, cellulose and holocellulose (the sum of cellulose and hemicellulose) in mixed silage treated with formic or acetic acid was significantly lower than that obtained in the negative control. The pH and the ratio of ammoniacal nitrogen to total nitrogen in mixed silage treated with acetic acid also significantly decreased. Furthermore, the addition of formic or acetic acid significantly weakened the fermentation intensity of lactic acid, depending on the ratio of lactic to acetic acid, as well as the ratio of lactic acid to total organic acids. The number of bacterial species and their relative abundance shifted during silage mixing, wherein microbial communities at phylum level mainly consisted of Proteobacteria and Firmicutes. The dominant bacteria were also observed to shift from Lactobacillus and Enterobacter in presilage biomass to Lactobacillus and Paralactobacillus. Specifically, Enterobacter disappeared after 130 days of storage. In conclusion, the addition of a low dose of acetic acid to fresh mass (0.3 %) could effectively improve the fermentation quality and is conducive to the preservation of the organic components.
