Summary: This study focuses on the viability of bacterial cultures in cementitious systems and their impact on the compressive strengths and microstructural changes of the resulting bacterial concrete. The results show that the selected bacterial strains can maintain viability for up to 15 days when stored at room temperature, and the bacterial concrete prepared with stored cultures exhibits improved compressive strength compared to control concrete samples.

Summary: The injectable in situ forming double-network hydrogel developed in this study plays a crucial role in cell transplantation by providing cell protection, long-term retention, and support for cell growth. These functions are achieved through dynamic cross-linking and secondary cross-linking networks in the hydrogel.

Summary: The article proposed a method for evaluating cell viability heterogeneity based on multiphysical property information fusion using polynomial regression. The method extracts data from cell detachment assays and IC50 assays, reducing the mean relative error by 6.04% and 62.79% compared to multiple linear regression and cell counting methods.

Summary: Thermal exposure increases metabolic rate and ROS level. Study on Fathead minnow (FHM) muscle cell line demonstrated that L-carnitine supplementation effectively mitigated metabolic stress at 37 degrees C. The results showed significant differences in oxidative parameters at higher temperatures, while L-carnitine inclusion at 0.5-1 mM concentrations was effective against metabolic stress.

Summary: The study identified strains able to tolerate or degrade the endocrine disruptor bisphenol A (BPA) from 30% of infant fecal microbial culture libraries, with most isolated strains phylogenetically related to the operational taxonomic group Bacillus amyloliquefaciens spp. Whole Genome Sequencing analysis of a representative Bacillus strain revealed four complete molecular pathways involved in BPA degradation, indicating high potential for BPA biodegradation. Pathways for the synthesis of Exopolysaccharide (EPS) and Polyhydroxyalkanates (PHA) biopolymers were also identified, with potential applications in capturing and depositing xenobiotics.

Summary: This study identified a pectinase-producing Bacillus sp. that exhibited multi-enzymes activities using various agro-wastes as substrates. The optimal cultural conditions were determined, and the bacterium was found to have the potential for producing bacterial lipids. It can be a good candidate for agro-waste degradation, waste management, and renewable biofuel production.

Summary: 3D printing technology is a convincing method for fabricating scaffolds for tissue replacement. In this study, polymer-ceramic composite 3D-printed scaffolds with silk fibroin infill were investigated for their cell adhesion. The presence of silk fibroin improved cell adhesion and viability, but the mechanical strength remained similar.

Summary: The study found that the application of silicon and Bacillus thuringiensis significantly reduced oxidative stress levels in lettuce plants exposed to salinity, while also enhancing leaf area, total yield, relative water content, and chlorophyll levels. Additionally, the treatment increased the expression of proline and antioxidant enzyme activity in lettuce leaves under salinity conditions.

Summary: FocTR4 infection induces the expression and activation of MaVPEs in susceptible cultivar, while the expression and activity are lower in resistant cultivar. Inhibiting MaVPE activity can reduce lesion formation and enhance stress tolerance against FocTR4 infection. The VPE-null mutant in Arabidopsis shows higher tolerance to FocTR4 infection. Comparative proteomic analysis reveals differential expression levels of proteases and protease inhibitors in susceptible and resistant cultivars.

Summary: The study showed that the Bacillus sp. P3 strain significantly enhanced enzymatic saccharification in corn stover, with an improved hemicellulose removal rate through the production of alkaline-resistant xylanase and other enzymes. After pretreatment with the P3 strain, the glucan content in corn stover increased by 51% and the yield of reducing sugar released during enzymatic hydrolysis was increased by 56% compared to untreated corn stover. The use of the P3 strain could be a promising approach for enhancing the enzymatic hydrolysis process in industrial bioenergy productions.

Summary: Drought stress is a major environmental factor that causes physiological and biochemical damages in plants. This study investigated the effectiveness of foliar application of ethionine (ETH) in improving drought tolerance and revealed how it alleviates drought stress. The results showed that foliar application of ETH effectively mitigated drought damages by enhancing root viability, antioxidant enzyme activities, soluble sugar contents, and isopentenyladenosine levels in tall fescue.

Summary: This study measured the activities of catalase (CAT) and glutathione S-transferase (GST) in blue mussels (Mytilus sp.) exposed to different concentrations of the fluoroquinolone antibiotic norfloxacin. H-1 nuclear magnetic resonance (H-1-NMR)-based metabolomics was used to study the metabolic effects of norfloxacin. The results showed that high concentrations of norfloxacin induced CAT activity and inhibited GST activity, and disrupted multiple pathways including energy metabolism, amino acid metabolism, neuroregulation, and osmotic pressure regulation. These findings provide a molecular and metabolic view of the effects of norfloxacin and its regulatory mechanism in blue mussels.
