Decoding microbiota and metabolite transformation in inoculated fermented suansun using metagenomics, GC-MS, non-targeted metabolomics, and metatranscriptomics:Impacts of different Lactobacillus plantarum strains.

Using metagenomics, GC-MS, non-targeted metabolomics, and metatranscriptomics, we investigated the microbial communities and metabolites in two different Lactobacillus plantarum fermentations. Metagenomics revealed Weissella cibaria dominantly contributed to the DACN766-fermented suansun (LPS1) and Lactiplantibacillus pentosus to the DACN760-fermented suansun (LPS2). GC-MS identified 38 and 40 flavor compounds in LPS1 and LPS2, respectively, with p-cresol, 4-hydroxybenzaldehyde, acetic acid, hexanal, and propionic acid crucial for aroma development.

Combination of extrusion and bamboo leaf flavonoids modulates in vitro maize starch digestion: Insight into the molecular mechanisms and multi-scale structure.

This study investigates the combined effects of extrusion processing and bamboo leaf flavonoids (BLFs) on the digestive properties and multiscale structure of maize starch (MS). Extrusion increased the levels of rapidly digestible starch (RDS) and slowly digestible starch while the content of resistant starch (RS) decreased to 20.19 %.

Metagenomic analysis of Lactobacillus plantarum DACN768 inoculation effects on volatile flavor compounds, microbial succession, and flavor metabolic network in suansun.

This study analyzed volatile flavor compounds and microbial communities in Lactobacillus plantarum-fermented suansun (LPS), emphasizing the underlying metabolic pathways. A comparison with naturally fermented suansun (NFS) identified 56 volatile flavor compounds in LPS, detected via GC-MS, with levels peaking at 14 days. Alcohols, aldehydes, and esters were the primary components in both NFS and LPS.

Integrated metagenomics and metatranscriptomics analyses reveal the impacts of different Lactiplantibacillus plantarum strains on microbial communities and metabolic profiles in pickled bamboo shoots.

Effects of two different Lactobacillus plantarum fermentation processes on microbial communities and metabolic functions were evaluated using metagenomics and metatranscriptomics. Dominant species in Lactobacillus plantarum DACN4208 (LPIF8) and DACN4120 (LPIF10) were Lactobacillus pentosus and Lactobacillus plantarum, with Lactiplantibacillus comprised 75.31 % of the microbial community in LPIF10.

Comprehensive evaluation of freezing tolerance in prickly ash and its correlation with ecological and geographical origin factors.

Low temperatures are a key factor affecting the growth, development, and geographical distribution of prickly ash. This study investigated the impact of ecological and geographical factors on the freezing tolerance of prickly ash germplasm. Thirty-seven germplasm samples from 18 different origins were collected, and their freezing tolerance was comprehensively evaluated.

Diversity analysis of panicle traits in Chinese prickly ash germplasm resources and their influence on its systematic classification.

This study aimed to reveal the diversity and variation in panicle traits of the Chinese prickly ash and clarify their influence on the its systematic classification to provide a theoretical basis and technical support for the efficient utilization of Chinese prickly ash germplasm resources and breeding. Sixteen panicle traits were identified from 35 Chinese prickly ash germplasm resources from 2021 to 2022. The diversity of these panicle traits and their role in the plant's systematic classification were studied using variance, correlation, cluster, and principal component analyses.

Rheological properties, multiscale structure, and in vitro digestibility of a maize starch-konjac glucomannan-bamboo leaf flavonoid complex modified by dynamic high-pressure microfluidization.

The effects of dynamic high-pressure microfluidization (DHPM) treatment on the rheological properties, multiscale structure and in vitro digestibility of complex of maize starch (MS), konjac glucomannan (KGM), and bamboo leaf flavonoids (BLFs) were investigated. Compared with MS, the MS-KGM-BLF complex exhibited reduced viscosity and crystallinity, along with increased lamellar thickness to 10.26 nm.

Leaf traits of prickly ash and its correlation with ecological and geographical factors of origin.

The morphological, physiological, and biochemical characteristics of leaves result from the long-term adaptation of plants to their environment and are closely related to plant growth and development. In this study, 37 prickly ash germplasm resources from 18 production areas were utilized as the subjects of research. Logistic equations, principal component analysis, and cluster analysis were employed to comprehensively evaluate the leaf traits of prickly ash germplasm resources, with an analysis of their correlation with ecological and geographical factors in the production areas.

Lotus starch/bamboo shoot polysaccharide composite system treated via ultrasound: Pasting, gelling properties and multiscale structure.

This study investigated the effects of ultrasound treatment on the physicochemical properties, digestion properties, and multiscale structure of a lotus root starch (LS) and bamboo shoot polysaccharide (BSP) composite system. It also preliminarily revealed the mechanism underlying the modification effect of ultrasound treatment. After 180-360 W ultrasound treatment, the viscosity, thixotropy, and gel viscoelasticity of the LS/BSP paste increased.

New insights into the interaction between bamboo shoot polysaccharides and lotus root starch during gelatinization, retrogradation, and digestion of starch.

In this study, the interaction between bamboo shoot polysaccharides (BSP) and lotus root starch (LS) during gelatinization, retrogradation, and digestion of starch was investigated. The addition of BSP inhibited the gelatinization of LS and decreased the peak viscosity, valley viscosity, and final viscosity. Amylose leaching initially increased and then decreased with the increase in BSP addition.

Effect of Zanthoxylum alkylamides on lipid metabolism and its mechanism in rats fed with a high-fat diet.

This research aimed at exploring the effect of Zanthoxylum alkylamides on lipid metabolism and its potential mechanisms using high-fat diet rat model. Treatment with Zanthoxylum alkylamides for 6 weeks, food efficiency and atherogenic index of the low, medium, and high doses of Zanthoxylum alkylamides-treated groups were significantly reduced. Meanwhile, the histopathological structure of the livers showed that hepatic steatosis in the groups treated with Zanthoxylum alkylamides was reduced, particularly the HD group.

The impact of the postharvest environment on the viability and virulence of decay fungi.

Postharvest decay of fruits, vegetables, and grains by fungal pathogens causes significant economic losses. Infected produce presents a potential health risk since some decay fungi produce mycotoxins that are hazardous to human health. Infections are the result of the interplay between host resistance and pathogen virulence.

Transcriptome Analysis Reveals the Mechanism Underlying the Production of a High Quantity of Chlorogenic Acid in Young Leaves of Lonicera macranthoides Hand.-Mazz.

Lonicera macranthoides Hand.-Mazz (L. macranthoides) is a medicinal herb that is widely distributed in southern China.

Hypoglycemic effects of Zanthoxylum alkylamides by enhancing glucose metabolism and ameliorating pancreatic dysfunction in streptozotocin-induced diabetic rats.

This study aimed to evaluate the hypoglycemic effect of Zanthoxylum alkylamides and explore the potential mechanism in streptozotocin (STZ)-induced diabetic rats. Diabetic rats were orally treated with 3, 6, and 9 mg per kg bw alkylamides daily for 28 days. As the alkylamide dose increased, the relative weights of the liver and kidney, fasting blood glucose, and fructosamine levels were significantly decreased.
