Summary: The rare pigment 8-isobutyl-12-ethyl-([,][I,E])bacteriochlorophyll (BChl) c plays a key role in the study of chlorosomal self-aggregation structures, and a method was developed for large-scale production of these pigments. Mutants overexpressing C8(2)-methyltransferase BchQ were constructed to successfully synthesize C8-hyper-alkylated BChl c and BChl d in bacterial cells, which can contribute to the development of new chlorosomal models and antenna devices for artificial photosynthesis.

Summary: Three strains of a new species of Gram-negative, anaerobic, motile, rod-shaped bacterium were isolated from biofilms in soda lakes in Mongolia and Russia. These strains, designated as B14B, A-7R, and A-7Y, had lamellar stacks and used bacteriochlorophyll a as their main photosynthetic pigment. They grew best at pH 9.0 and 0% NaCl, and could utilize various organic compounds for growth. The genomic analysis showed that they are distinct from other Ectothiorhodospira species and possess a unique nitric oxide reduction pathway.

Summary: Chlorosomes from green bacteria have efficient light capture and energy transfer abilities, inspiring developments in artificial light-harvesting and molecular optoelectronics. We examine two different organizations of the molecular building blocks and show how they affect light capture and energy transfer, potentially allowing the bacteria to adapt to changes in light conditions. Spectral simulations reveal how changes in the helicity of chlorosomal aggregates alter energy transfer, with contrasting energy pathways in different chlorosomes.

Summary: An ultra-fast and facile method using microwave assistance has been proposed to prepare sulfur/graphene composites for lithium-sulfur batteries. This method allows sulfur to quickly and uniformly deposit on the surface of graphene within just 30 seconds, producing nano-sized sulfur particles. The lithium-sulfur batteries made with these composites exhibit good cycling life with a capacity of 503.5 mAh g(-1) at 0.2 C, making practical application possible.

Summary: In this study, two simple, rapid, selective, and sensitive potentiometric sensors were developed for quantitative analysis of a extremolyte/osmoprotector, ectoine, in bacterial cultures and pharmaceutical products. The sensors exhibited fast and linear responses over a broad range of concentrations. The proposed methods were optimized and cross-validated with a HPLC method, showing no significant difference in accuracy and precision. The proposed procedures were also evaluated for their greenness and environmental impact, and were found to be excellent eco-friendly analytical methods.

Summary: The study aimed to evaluate the postharvest conservation of 'BRS Nubia' hybrid table grapes using a new technology called field ultra-fast SO2-generating pad (FUFR) before packaging and dual-release SO2-generating pad (DR) during cold storage. The results showed that both pads were effective in controlling gray mold and reducing grape mass loss, and they had no influence on stem browning, chemical properties, and color attributes of the berries.

Summary: The synthesis of ultra-small silver nanoparticles (AgNPs) using citrus peel residues as reducing and stabilizing agents and their antibacterial activity against multidrug-resistant clinical Staphylococcus aureus were studied. The AgNPs were characterized by various techniques, showing ultra-small, monodisperse, quasi-spherical morphology with an average particle size of 2.42 nm. XRD analysis confirmed the crystal size of the AgNPs. The AgNPs exhibited potent inhibitory activity against resistant S. aureus, suggesting their potential in combating clinical multi-resistant bacterial strains.

Summary: Potassium-ion batteries have attracted significant attention due to the abundance and low cost of potassium. However, their performance is limited by the large size of potassium ions. Researchers have developed sulfur-doped carbon spheres with hierarchically-mesoporous architecture, which exhibit impressive reversible capacity and rapid diffusion characteristics.

Summary: Geranylgeranyl reductase (GGR) catalyzes the hydrogenation of unsaturated hydrocarbons in isoprenoid compounds, producing various pigments in organisms. Halorhodospira halochloris GGR performs a unique double hydrogenation reaction to produce bacteriochlorophylls with a tetrahydrogeranylgeranyl tail. The study also created a variant enzyme that only performs single hydrogenation, providing insights into catalytic mechanisms of multiposition reductions by a single enzyme.

Summary: This study demonstrates that GGR from H. halochloris catalyzes the initial reduction of the C6 = C7 double bond and the further hydrogenation of the C14 = C15 double bond. Additionally, the reduction of GG to phytyl group in Blastochloris viridis occurs in two stages.
