Abstract	L-ascorbic acid (ASA) is a micronutrient that is essential for reproduction, growth, and immunity in animals. Due to the loss of enzyme L-gulono-1,4-lactone oxidase (GLO), most aquatic animals lack the capacity for ASA biosynthesis and therefore require supplementation with exogenous ASA. Recent studies have shown that 2-keto-L-gulonic acid (2KGA), a novel potential precursor of ASA, can enhance plant growth and improve stress resistance by promoting the synthesis and accumulation of ASA. Our hypothesis is that 2-keto-L-gulonic acid (2KGA) plays a similar role in aquatic animals. To investigate this, we conducted an in vivo trial to examine the effects of exogenous 2KGA supplementation on ASA metabolism and growth of zebrafish (Danio rerio). Zebrafish were categorized into groups based on their dietary intake, including a basal diet (CK group), a basal diet supplemented with 800 mg/kg ASA (ASA group), and 800 mg/kg 2KGA-Na (2KGA group) for a duration of three weeks. The results demonstrated a significant increase in ASA content in zebrafish treated with 2KGA (34.82% increase, p < 0.05) compared to the CK group, reaching a consistent level with the ASA group (39.61% increase, p < 0.05). Furthermore, the supplementation of 2KGA significantly improved growth parameters relevant to zebrafish (specific growth rate increased by 129.04%, p < 0.05) and enhanced feed utilization (feed intake increased by 15.65%, p < 0.05). Positive correlations were observed between growth parameters, feed utilization, whole-body chemical composition, and ASA content. Our findings suggest that supplementation with exogenous 2KGA can serve as a novel approach for elevating ASA synthesis in aquatic animals, and further investigation of its underlying mechanism is required.

Abstract	Laboratory animals with human microbiome have increasingly been used to study the role of bacteria and host interaction. Drosophila melanogaster, as a model of microbiota-host interaction with high reproductive efficiency and high availability, has always been lacking studies of interaction with human gut microbiome. In this study, we attempted to use antibiotic therapy and human fecal exposure strategy to transfer the human microbiome to the drosophila. The method includes depleting the original intestinal bacteria using a broad-spectrum antibiotic and then introducing human microorganisms by a diet supplemented with donor’s fecal samples. The sequencing results showed that 80–87.5% of the OTUs (Operational Taxonomic Units) from donor feces were adopted by the recipient drosophila following 30 days of observation. In comparison to females, the male recipient drosophila inherited more microbiota from the donor feces and had significantly increased lifespan as well as improved vertical climbing ability. Furthermore, distinctly differential expression patterns for age and insulin-like signaling-related genes were obtained for the male vs. female recipients. Only the male drosophila offspring acquired the characteristics of the donor fecal microbiota.

Abstract	The potential of industrial effluents from vitamin C (VC) production was assessed for agricultural applications by monitoring plant growth, soil properties, and microbial community structure. The results demonstrated that two types of effluents—residue after evaporation (RAE) and concentrated bacterial solution after ultrafiltration (CBS)—had positive effects on the yield and VC content of pak choi. The highest yield and VC content were achieved with a combined RAE-CBS treatment (55.82 % and 265.01 % increase, respectively). The soil fertility was also enhanced by the application of RAE and CBS. Nitrate nitrogen and organic carbon contents in the soil were positively correlated with the RAE addition, while ammonium nitrogen and available phosphorus were positively correlated with the CBS addition. The diversity of bulk and rhizosphere soil bacterial communities increased significantly after the addition of RAE-CBS. The abundance of Sphingomonas and Rhizobium significantly increased after the RAE-CBS treatment, which affected aromatic compound hydrolysis and nitrogen fixation positively. Changes in plant growth and soil fertility were closely related to the upregulation of functional gene expression related to C, N, and P cycling. RAE and CBS application exerted various positive synergistic effects on plant growth, soil fertility, and bacterial community structure. Consequently, the study results confirmed the potential of RAE and CBS application in agriculture. This study provides an innovative solution for utilizing VC industrial wastewater in agriculture in a resourceful and economically beneficial manner while alleviating the corresponding environmental burden.

Abstract	The insulin receptor (InR) pertains to the insulin receptor family, which plays a key role in the insulin/insulin-like growth factor (IGF)-like signaling (IIS) pathway. Insulin signaling defects may result in the development of metabolic diseases, such as type 2 diabetes, and the InR mutant has been suggested to bear insulin signaling deficiency. Numerous studies have reported that probiotics are beneficial for the treatment of diabetes; however, the effect of probiotics on patients with

Abstract	The potential of industrial effluents from vitamin C (VC) production was assessed for agricultural applications by monitoring plant growth, soil properties, and microbial community structure. The results demonstrated that two types of effluents-residue after evaporation (RAE) and concentrated bacterial solution after ultrafiltration (CBS)-had positive effects on the yield and VC content of pak choi. The highest yield and VC content were achieved with a combined RAE-CBS treatment (55.82 % and 265.01 % increase, respectively). The soil fertility was also enhanced by the application of RAE and CBS.

Abstract	The research took Trichoderma strain as tested strains which isolated from the rhizosphere of healthy and high yield pepper, M2 was classified and identified by combining morphological classification with molecular identification means(rDNA-ITS sequence analysis), whose effect on growth of Brassica chinensis L. was explored, in order to provide superior strains for bio-fertilizer development. After solid fermentation of Trichoderma M2, under the condition of the greenhouse, took some research on the growth promoting effect on Brassica chi nensis L. of Trichoderma M2. The results showed that the strain M2 was identified as Trichoderma harzianum strain. M2 had obvious effects on promoting growth, the SPAD and edible leaf number of Brassica chinensis L. Adding of 5.0×10 9 cfu M2 had the best effect on increasing the biological yield. Compared with CK, fresh weight and dry weight was increased by 30.26%and 20.08%respectively. Followed by inocula tion of 5.0×10 8 cfu M2, fresh weight and dry weight was increased by 18.33% and 12.46% respectively. Therefore, M2 showed evident promoting effect on Brassica chinensis L., and had potential application value.

Abstract	Salt stress has long been a prominent obstacle that restricts crop growth, and increasing the L-ascorbic acid (ASA) content of crops is an effective means of alleviating this stress. 2-Keto-L-gulonic acid (2KGA) is a precursor used in industrial ASA production as well as an ASA degradation product in plants. However, to date, no study has investigated the effects of 2KGA on ASA metabolism and salt stress. Here, we evaluated the potential of using 2KGA to improve crop resistance to salt stress (100mM NaCl) through a cultivation experiment of non-heading Chinese cabbage (

Abstract	To prepare fermentable hydrolysate from corncob residue (CCR), Trichoderma strain G26 was cultured on medium containing CCR for production of cellulolytic enzymes through solid-state fermentation (SSF), resulting in 71.3 IU/g (FPA), 136.2 IU/g (CMCase), 85.1 IU/g (β-glucosidase) and 11,344 IU/g (xylanase), respectively. Through a three-stage saccharification strategy, CCR was hydrolyzed by the enzymatic solution (6.5 FPU/ml) into fermentable hydrolysate containing 60.1g/l glucose (81.2% cellulose was converted at solid loading of 12.5%), 21.4% higher than that by the one-stage method. And then the hydrolysate was used to produce L-lactic acid by a previous screened strain Bacillus coagulans ZX25 in the submerged fermentation. 52.0 g/l L-lactic acid was obtained after fermentation for 44 h, with 86.5% glucose being converted to L-lactic acid. The results indicate that the strains and the hydrolysis strategy are promising for commercial production of L-lactic acid from CCR and other biomass.
