The influence of synergistic antibacterial saponins, sapindoside A and B, on the fatty acid composition and membrane properties of Micrococcus luteus.

Background: Saponins from Sapindus mukorossi Gaertn. are natural surfactants with excellent foaming ability, biodegradability, and safety. However, their applications in food have been rarely reported.

The effect of Mesona blume straw fermented by Ganoderma lucidum to improve physicochemical, in vitro digestion and gut bacteria of noodles.

Mesona blume straw (MBS) is a class of high-fiber, low-value Mesona blume's colloid by-products. We investigated the changes in dietary fiber (DF), triterpenoid, and polysaccharide contents of fermented Mesona blume straw (FMBS) by Ganoderma lucidum (GL), we also examined the effect of adding FMBS at different levels (0 %, 5 %, 10 %, and 15 %) on cooking quality, texture, in vitro starch digestibility and in vitro fermentation broth properties and gut bacteria of noodles. The results showed that after fermentation, soluble dietary fiber (SDF) increased by 16.

The impact of crowding stress on growth and intestinal integrity in largemouth bass (Micropterus salmoides): Insights into ER stress, autophagy and apoptosis.

Crowding stress is a common abiotic stressor in intensive aquaculture that negatively impacts fish species, leading to growth depression. This study primarily explored the effects of crowding stress on the growth and intestinal integrity of largemouth bass (Micropterus salmoides). A 10-week feeding experiment was conducted with two groups: a control group (0.

Potential prebiotic effects of soy by-products as novel dietary fibre: Structure, function, in vitro simulation of digestion and fermentation properties.

This study aimed to prepare soybean dregs dietary fibre (DF) using physically assisted chemical (KHMSO) modification and study its structure, function and vitro simulation experiments. The soluble dietary fibre (SDF) content in KHMSO increased and insoluble dietary fibre (IDF) content decreased. The modified DF surface becomes irregular and rough, and the results of XPS fitting indicated that the DF structure had different peak-splitting groups.

Apoptosis Inducing Factors Involved in the Changes of Flesh Quality in Postmortem Grass Carp () Muscle.

Alterations of apoptosis have notable influences on flesh quality, but the mechanism is still unclear. Thus, apoptotic behaviors and related triggering mechanisms need to be explored. Fish muscle was prepared and stored at 4 °C for 0, 24, 48, 72, 96, and 120 h for apoptosis analysis.

Research on apoptotic mechanism and related pathways involved in postmortem grass carp (Ctenopharyngodon idellus) muscle.

Background: Apoptosis activation is an essential research to reveal the triggering mechanism of flesh quality deterioration. This study was aimed at explaining apoptotic mechanism of postmortem fish in terms of caspases activation, cytochrome c (cyt-c) release, B-cell lymphoma 2 (Bcl-2) and Bcl2-associated X (Bax) protein levels, transcriptional levels of its molecules, and apoptosis-inducing factor (AIF) translocation at 4 °C for 5 days.

Results: Activation of caspase-9, caspase-8, caspase-3 and the release of mitochondrial cyt-c were observed during storage.

The apoptosis of grass carp (Ctenopharyngodon idella) muscle during postmortem condition regulated by the cytokines via TOR and NF-κB signaling pathways.

Postmortem alteration by apoptosis has significant effects on flesh quality. Currently, the information necessary to understand the apoptotic behavior and the molecular mechanisms during postmortem alteration in fish muscle is still lacking. Activation of apoptosis and the cytokines involved in regulating apoptosis in fish muscle were evaluated during postmortem condition at 4 °C for 5 days in terms of apoptotic morphology changes, nucleus DNA fragmentation, caspases activation and related gene expressions.
