Summary: This study identified eight bacterial strains from the low-permeability reservoir in the Ordos Basin that can produce biosurfactants and reduce viscosity. These strains can emulsify oil, tolerate different temperatures, salinity, and pH, and effectively degrade certain chemicals in oil. Additionally, they can reduce oil viscosity. The findings have important implications for the application of microbial-enhanced oil recovery in low-permeability oil fields.

Summary: Plants in natural ecosystems face threats from microbial diseases, but have developed a strong immune system to combat infections. Antimicrobial peptides (AMPs) in plants are environmentally friendly, anti-pathogenic, and safe for humans. A new isolation technique using high-throughput cDNA libraries and the Bacillus subtilis expression system allows for large-scale screening of unique or homologous AMPs.

Summary: Using Raman tweezers and live-cell phase-contrast microscopy, this study characterized the lysis process of individual Bacillus subtilis cells carrying PBSX prophage during spores' germination, outgrowth, and vegetative growth. The findings showed that nucleic acid intensities in induced cultures decreased rapidly after prophage induction, with a delay before cell burst, and the latent time and burst time varied in cell populations under different culture conditions.

Summary: In this study, two antimicrobial peptides (CgR2150 and CgR3101) with broad-spectrum antibacterial activities were identified from endophytes isolated from potato tubers. These peptides showed excellent stability and could significantly inhibit the growth of various bacteria and fungi. Scanning electron microscopy revealed that these peptides disrupt bacterial cell membranes. The findings suggest that CgR2150 and CgR3101 have potential as new antibacterial agents.

Summary: In this study, bacterial nanocellulose and polyhydroxyalkanoate biopolymers were extracted and synthesized into biopolymer films with improved properties. The films exhibited higher crystalline properties, increased thickness, tensile strength, and elongation, as well as decreased solubility and swelling degree compared to the biopolymer-free film. The findings suggest that the BNC and PHA biopolymer-based films have potential applications in sustainable packaging.

Summary: This study isolated a highly productive laccase-producing bacteria, Bhargavaea bejingensis, from soil samples collected from the paper and pulp industry. The extracellular and intracellular laccase activities of the bacteria after 24 h incubation were 1.41 U/mL and 4.95 U/mL, respectively. The laccase-encoding gene of this bacteria was sequenced and bioinformatically characterized to be structurally and sequentially homologous to the CotA protein of Bacillus subtilis. The laccase produced by B. bejingensis was classified as a three-domain laccase with several copper-binding residues.

Summary: The C-terminal domain of the α subunit of RNA polymerase is targeted by transcriptional regulators in the activation of transcription. In bacteria, the regulator binds to DNA at different sites and interacts with the α CTD to stabilize the RNA polymerase at the promoter or form a pre-recruitment complex. In B. subtilis, the binding of RNA polymerase at the promoter stabilizes the transcriptional regulator and facilitates open complex formation. Two residues of the α CTD are essential for this process.

Summary: In this study, a combined electrooxidation and electrocoagulation (EO-EC) reactor was used to treat Cu-EDTA wastewater, with parameters like current density, electrolyte, and NaCl concentration found to affect the treatment efficiency. Under specific conditions, high Cu-EDTA removal efficiency was achieved, possibly through the generation of various oxidation and mineralization products. Overall, the EO-EC process proved to be an effective method for treating Cu-EDTA contaminated wastewater.

Summary: The study found that biochar nanoparticles can enhance the mobility of Cd2+, but the transport of biochar is limited in the presence of Cd2+. Additionally, the ability of nZVI-NBC to rerelease Cd2+ is weaker than that of NBC, as oxidized nZVI is more easily retained in the sand column, strengthening the immobilization of Cd2+.

Summary: The emerging contaminants PHCZs have been detected globally in soils and sediments, showing dioxin-like toxicity. This study investigated the degradation of 3,6-DCCZ in soil, finding transformation to 3-CCZ and changes in soil bacterial community structure due to exposure. The results suggest that exposure to 3,6-DCCZ affects soil microbial processes related to nitrification, nitrogen fixation, denitrification, carbon dioxide fixation, and hydrocarbon degradation.
