“…This is in line with another study in which the LA and AA levels decreased in silage as the proportion of pistachio hulls increased [29]. Chen et al [30] reported that a low moisture content is detrimental to LA accumulation. This can be attributed to the reduced activity of the bacteria in a low-moisture environment, resulting in a lower concentration of fermentation acid [31].…”

The aim of the experiment was to investigate the effect of different ratios of excipient (millet hull or wheat bran) and LAB inoculation on the fermentation quality and in vitro digestibility of a mixed silage of SCPBs. The preliminary experimental results showed that inoculating with lactic acid bacteria (LAB) directly in the fresh sweet corn processing byproduct (SCPBs) silage had a higher ammonia nitrogen/total nitrogen (AN/TN) ratio and lower silage fermentation quality due to high moisture content. Subsequently, millet hull or wheat bran were mixed with SCPBs in a 7:3 (T1), 8:2 (T2), and 9:1 (T3) ratio and ensiled with LAB. Under the condition of each mixing ratio, the silage treatments were categorized into groups without any additives (control) and with LAB. Fermentation quality, in vitro digestibility, chemical composition, and energy values were determined after 45 days of silage. The pH, AN/TN, neutral detergent fiber, acid detergent fiber, and acid detergent lignin were lowest in the SCPBs and millet hull mixed silage (SMH) group under the T3 treatment, whereas they were lowest in the SCPBs and wheat bran mixed silage (SWB) group under the T2 treatment. The mean lactic acid and acetic acid values were higher in the SWB group than in the SMH group (6.92, 6.81 vs. 4.00, 4.52). Under the T3 treatment in the SMH group, AN/TN was significantly reduced with the addition of LAB (4.52 vs. 4.37, p < 0.05). The SMH group had the highest crude protein (CP) under the T3 treatment, whereas the SWB group had the highest CP under the T2 treatment. The mean CP in the SWB group was higher than that of the SMH group (18.17, 19.44 vs. 10.55, 10.55). Under the T1 treatment, in the SWB group, the addition of LAB resulted in a significant increase in in vitro crude protein digestibility (p < 0.05). The results showed that silage fermentation quality and in vitro digestibility improved with the addition of LAB. The optimum mixing ratio for the SWB group was 9:1 and 8:2 for the SMH group.

“…Accordingly, a recent report demonstrated that supplementation of garlic skin improved the growth performance of lambs by altering the ruminal bacterial composition by increasing the relative abundances of certain genera while decreasing others [37]. Garlic skin also improved the fermentation quality of high-moisture silages by increasing the abundance of Lactobacillus and decreasing the relative abundance of Clostridium [38]. Notably, although garlic peels and cloves displayed different effect on microbial growth, all parts of the bulb inhibited microconidia germination and hyphae branching of the pathogenic fungus Fusarium oxysporum f.sp.…”

Plants have two types of reproduction: sexual, resulting in embryo production, and asexual, resulting in vegetative bodies commonly derived from stems and roots (e.g., bulb, tuber). Dead organs enclosing embryos (DOEEs, such as seed coat and pericarp) are emerging as central components of the dispersal unit acting to nurture the embryo and ensure its survival in the habitat. Here we wanted to investigate the properties of dead organs enclosing plant asexual reproductive bodies, focusing on the garlic (Allium sativum) bulb. We investigated the biochemical and biological properties of the outer peel enclosing the bulb and the inner peel enclosing the clove using various methodologies, including bioassays, proteomics, and metabolomics. The garlic peels differentially affected germination and post-germination growth, with the outer peel demonstrating a strong negative effect on seed germination of Sinapis alba and on post-germination growth of Brassica juncea. Proteome analysis showed that dead garlic peels possess 67 proteins, including chitinases and proteases, which retained their enzymatic activity. Among primary metabolites identified in garlic peels, the outer peel accumulated multiple sugars, including rhamnose, mannitol, sorbitol, and trehalose, as well as the modified amino acid 5-hydroxylysine, known as a major component of collagen, at a higher level compared to the clove and the inner peel. Growth of Escherichia coli and Staphylococcus aureus was promoted by garlic peel extracts but inhibited by clove extract. All extracts strongly inhibited spore germination of Fusarium oxysporum f.sp. melonis. Thus, the garlic peels not only provide physical protection to vegetative offspring but also appear to function as a refined arsenal of proteins and metabolites for enhancing growth and development, combating potential pathogens, and conferring tolerance to abiotic stresses.

“…In general, most metabolic categories increased over time, which indicates that the metabolic intensity of the microbial community increased as microbial diversity and abundance increased ( Qiu et al, 2018 ). High abundances of beneficial microorganisms were detected in the LAB treatments, which are the primary factors causing these types of metabolism to be active ( Chen J. et al, 2021 ; Du et al, 2021 ). In addition, the high amino acid biosynthesis activity indicates that adding LAB allows macromolecular proteins present in the silage to be degraded into amino acids or peptides that are easily absorbed by the body ( Du et al, 2020 ).…”

The purpose of this study was to investigate the effects of inoculation with two lactic acid bacteria (LAB) strains (Lacticaseibacillus rhamnosus and Lentilactobacillus buchneri) and the addition of four corn flour proportions (0, 3, 6, and 9%) in different treatments, on the composition and function of the bacterial community in whole-plant paper mulberry silage. The different treatments promoted Lactiplantibacillus, Lentilactobacillus, and Lacticaseibacillus growth, but the microbial species responsible for fermentation differed among the treatments. High species diversity and various Gram-negative bacteria, such as Flavitalea sp., Pantoea agglomerans, Acinetobacter pittii, Turicibacter sanguinis, and Ralstonia pickettii, were found in the uninoculated LAB treatments. A beneficial bacterium, Lactobacillus johnsonii, was discovered for the first time in whole-plant paper mulberry silage. LAB inoculation simplifies the microbial community structure, and beneficial Lactobacillus as a key species aggregates in the inoculated treatment group. However, L. rhamnosus inoculation alone may have limited bacteriostatic activity against in whole-plant paper mulberry silage. Compared with silage lacking corn flour, amino sugar and nucleotide sugar metabolism, galactose metabolism, the phosphotransferase system and the pentose phosphate pathway metabolic activity were increased in corn flour-containing silage. Whole-plant paper mulberry can be used as a high-quality silage to provide high-quality feed resources for sustainable ruminant livestock production. Moreover, additive use is necessary for preparing paper mulberry silage.
