The Potential of Bacterial Strains of Luteovulum sphaeroides W22 and W47 for Producing δ-Aminolevulinic Acid to Improve Soil Quality, Growth and Yield of Saline-Irrigated Rice Cultivated in Salt-Contaminated Soil

Agronomy, 2023
The present study aimed to identify the abilities of the δ-aminolevulinic acid (ALA) producing purple non-sulfur bacteria (PNSB), Luteovulum sphaeroides W22 and W47, to reduce the Na+ concentration, and to ameliorate the soil fertility, nutrients uptake,

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Inside‐Outside ROS Therapeutic Strategy Based on Piezoelectric Nano‐Urchin for Drug‐Resistant Bacteria Biofilm Infections

Advanced Science, EarlyView.
The contribution of this study lies not only in enabling effective treatment of drug‐resistant biofilm infections, but also in establishing a transferable therapeutic paradigm: Ultrasound‐triggered mechanical forces synergistically enhance piezoelectric polarization and nanozyme activity, driving functional ROS generation inside and outside biofilms ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Thermostable nature of hydrogen production by non-sulfur purple photosynthetic bacteria isolated in Thailand. [PDF]

Agricultural and Biological Chemistry, 1981
Ten strains of non-sulfur purple photosynthetic bacteria were isolated from soil and water samples gathered in Bangkok and its surrounding area. The isolated strains from Thailand were divided into two groups, Al to A4 and BI to B6. They were identified as Rhodopseudomonas gelatinosa and Rhodopseudomonas sphaeroides, respectively. All strains grew well

Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

Advanced Science, EarlyView.
Chronic diabetic wounds are hindered by a “dual trap” of biofilm resistance and hyperinflammation. A mesoporous catalytic‐adsorptive nano‐regulator is developed to dismantle this barrier through simultaneous eDNA degradation and LPS sequestration. By silencing TLR4/9‐mediated signaling, the platform clears resilient pathogens and reprograms the immune ...

A Simple Thermodynamic Analysis of Photosynthesis

Entropy, 2007
In this paper we present a comparative study of nine photosynthetic pathways bymeans of their thermodynamic performance. The comparison is made by using the thermalefficiency of light-to-chemical energy conversion and the so-called ecological ...
