“…The feed–water ratio impaired water content in SSF, which influenced the metabolic activity and rate of LAB. However, additional water will increase the water content of the final FA product, which is not conducive to the dry and storage (shelf-life) of products thus adding the cost (Dong et al, 2022a ). As for the inoculation ratio and glucose addition, the turning point was chosen based on the consideration that further increases beyond this point would not yield significant gains but would result in heavier cost burdens.…”

Astragalus is a homologous medicine and food that benefits human beings and poultry rearing. Fermented astragalus (FA) is a valuable product obtained by fermentation, but its scale-up production requires optimization and expansion of solid-state fermentation (SSF). In this study, Lactobacillus pentosus Stm was screened as the most suitable LAB strain for fermenting astragalus due to its excellent capacity. After optimization and expansion of SSF, LAB count and lactic acid content reached 206 × 108 cfu/g and 15.0%, respectively. Meanwhile, the content of bioactive compounds in FA was significantly enhanced. Feeding experiments with laying hens indicated that supplementing FA in the diet significantly improved the performance and egg quality, as evidenced by reduced feed-to-egg ratio and egg cholesterol. This was due to the promotion of intestinal health by shifting intestinal microbiota. Therefore, this is a systematical endeavor of producing scaled-up FA with promising potential as a feed additive in the poultry breeding industry.

“…Several studies have been conducted on the hydrolysis of mannans from various lignocellulosic agricultural wastes such as copra meal (Sornlake et al, 2013;Suryawanshi & Kango, 2021); spent coffee grounds (Erkan et al, 2021;Cho et al, 2022), palm kernel cake (Li et al, 2018;Dong et al, 2022), etc. For example, Intaratrakul et al (2022 reported the optimised conditions for the production of MOS from defatted copra meal using a recombinant β-mannanase from Bacillus circulans NT6.7.…”

The β-mannanase present in the commercial enzyme Pectinex Ultra SP-L was characterised and tested for its ability to hydrolyse copra meal for the production of mannooligosaccharides (MOS). The optimum pH and temperature for the mannanase activity were 4.0 and 65 °C, respectively. The relative activity of the β-mannanase of the commercial preparation Pectinex Ultra SP-L on copra meal was 49% when compared to the complete hydrolysis of locust bean gum, indicating its potential to hydrolyse the agricultural waste. The maximum MOS concentration of 25 g L −1 was obtained from the hydrolysis of 300 g L −1 copra meal with Pectinex Ultra SP-L at 55 °C for 2 h. The hydrolysate consisted of ~45% oligosaccharides and the rest were monosaccharides. Mannobiose and mannotriose were the only oligosaccharides present in the mixture, with mannobiose accounting for 90%. A simple and efficient method to obtain oligosaccharides from copra meal using a commercial pectinolytic enzyme is presented.
