Emerging contaminants often arise as by-products of technological advances,(bio)transformation products, or replacements for previously regulated chemicals. Once released into the environment, they present a significant threat to human health within the One health framework. Among various strategies for contaminant remediation, microbial-based initiatives are particularly promising for the removal and remediation of emerging contaminants due to their environmentally friendly characteristics, such as minimal chemical use and reduced energy consumption.

This study aimed to investigate the effects of different proportions of dietary fermented sweet potato residue(FSPR) supplementation as a substitute for corn on the nutrient digestibility, meat quality, and intestinal microbes of yellow-feathered broilers. Experiment 1(force-feeding) evaluated the nutrient composition and digestibility of mixtures with different proportions of sweet potato residue(70%, 80%,90%, and 100%) before and after fermentation. In Experiment 2(metabolic growth), a total of 420 oneday-old yellow-feathered broilers were randomly allocated to 4 groups and fed corn-soybean mealbased diets with 0, 5%, 8%, and 10% FSPR as a substitute for corn. The force-feeding and metabolic growth experiments were performed for 9 and 70 d, respectively. The treatment of 70% sweet potato residue(after fermentation) had the highest levels of crude protein, ether extract, and crude fiber and improved the digestibility of crude protein and amino acids(P < 0.05). Although dietary FSPR supplementation at different levels had no significant effect on growth performance and intestinal morphology, it improved slaughter rate, half-chamber rate, full clearance rate, and meat color, as well as reduced cooking loss in the breast and thigh muscles(P < 0.05). Dietary supplementation with 8% and 10% FSPR increased the serum immunoglobulin M and immunoglobulin G levels in broilers(P < 0.05). Furthermore, 10% FSPR increased the Shannon index and Ruminococcaceae＿UCG-014, Ruminococcaceae＿UCG-010 and Romboutsia abundances and decreased Sutterella and Megamonas abundances(P < 0.05). Spearman's correlation analysis showed that meat color was positively correlated with Ruminococcaceae＿UCG-014(P < 0.05) and negatively correlated with Megamonas(P < 0.05). Collectively, 70% sweet potato residue(after fermentation) had the best nutritional value and nutrient digestibility. Dietary supplementation with 8% to 10%FSPR as a substitute for corn can improve the slaughter performance, meat quality

镉(Cd)作为一种生物非必需的有毒重金属,通过自然排放或人类活动进入环境,对人类健康构成威胁。在微生物中高效表达金属螯合蛋白(MCP)可以增强生物对Cd的吸附能力。本研究构建了mcp基因编码的MCP的异源表达体系(GEM01),探究了其对Cd的吸附效果和潜在机制。结果表明,Cd^(2+)调控GEM01中mcp基因丰度,mcp基因的表达增加了Cd^(2+)的生物吸附能力(8.09 mg/g,比对照组高2.32倍)。在GEM01自溶过程中Cd^(2+)的保留率为87.87%。荧光光谱和分子动力学模拟表明了Cd^(2+)与MCP之间存在较强的相互作用且Cd^(2+)影响了MCP的二级结构。FT-IR证明了MCP中的官能团(如羧基、甲基和亚甲基)参与了MCP与Cd^(2+)的相互作用。分子对接进一步表明MCP蛋白表面的一些极性和亲水残基(如天冬酰胺、谷氨酰胺、丝氨酸和组氨酸)通过静电引力与Cd^(2+)结合。本研究为MCP介导的Cd^(2+)生物修复提供了新的见解,为微生物修复重金属污染提供了基因资源。

Lactate is present at a high level in the microenvironment of mammalian preimplantation embryos in vivo and in vitro. However, its role in preimplantation development is unclear. Here, we report that lactate is highly enriched in the nuclei of early embryos when major zygotic genome activation(ZGA) occurs in humans and mice. The inhibition of its production and uptake results in developmental arrest at the 2-cell stage, major ZGA failure, and loss of lactate-derived H3K18lac, which could be rescued by the addition of Lac-Co A and recapitulated by overexpression of H3K18R mutation. By profiling the landscape of H3K18lac during mouse preimplantation development, we show that H3K18lac is enriched on the promoter regions of most major ZGA genes and correlates with their expressions. In humans, H3K18lac is also enriched in ZGA markers and temporally concomitant with their expressions. Taken together, we profile the landscapes of H3K18lac in mouse and human preimplantation embryos, and demonstrate the important role for H3K18lac in major ZGA, showing that a conserved metabolic mechanism underlies preimplantation development of mammalian embryos.
