This study aimed to explore key physicochemical characteristics and evolutionary patterns of microbial community structure during the fermentation of aged vinegar. The correlation between microorganisms and physicochemical characteristics during fermentation was examined. The results revealed significant differences in genera at different stages of fermentation. The dominant bacteria in R1 were , , , and . During the R2 fermentation stage, , , and exhibited an upward trend and finally became the dominant bacteria. Aspergillus was the main bacterial genus at the end of overall fermentation. The correlation analysis showed that the bacterial genera significantly positively and negatively correlated with reducing sugars and amino acid nitrogen were the same in Cuqu. Similarly, the bacterial genera significantly positively and negatively correlated with pH and saccharification power were the same. pH, reducing sugar, and saccharification ability were mainly positively correlated with bacterial genera during fermentation. Further, studies found that the overall correlation between fungal communities and physicochemical characteristics was weaker than the correlation with bacteria during fermentation.

DNA is a dynamic molecule composed of numerous genic and regulatory elements that orchestrate cellular functions. Traditional methods often fail to provide accurate functional genome annotations because they do not effectively account for sequence variability within and across different organisms. To address this, we conducted an extensive genomic physical fingerprinting of ~4.

Hypothesis: The surface free energy (γ) and solubility (δ) parameters are two important characteristic parameters describing physicochemical properties of substances, but knowledge about the characteristic parameters (γ and δ) of surfactants is still lacking. Possible relationships of the characteristic parameters of surfactants with their head group types and alkyl chain lengths as well as with the surface tension (σ) of their aqueous solutions are worth exploring.
Methods: Solid surfactants including 10 anionic and 14 cationic ones were chosen.

Surfactant-enhanced aquifer remediation (SEAR) is an effective strategy for removing dense non-aqueous phase liquids (DNAPLs) from contaminated groundwater. While Gemini surfactants possess unique dimeric structures and excellent physicochemical properties, the role of hydrophobic chain length in governing their solubilization performance has not been systematically clarified. Here, five sugar-based anionic-nonionic Gemini surfactants (SANG 06, 08, 09, 10, and 13) with different hydrophobic chain lengths were synthesized and evaluated.

Addressing the issues of slow decomposition and low nutrient release efficiency associated with traditional straw returning, this study innovatively applied ultrasound-assisted centrifugal separation technology to prepare submicron/nano-straw particles and systematically conducted a multi-scale investigation from microscopic to macroscopic levels. The core finding reveals that when the particle size reaches the 1 μm threshold, ultrasonic cavitation vigorously disrupts the straw structure, leading to efficient lignin removal (77.45 %) and a significant reduction in cellulose crystallinity, thereby fundamentally enhancing the degradation rate.
