Phenotypic and Transcriptomic Analyses of Mildly and Severely Salt-Stressed Bacillus cereus ATCC 14579 Cells [PDF]

, 2009
Bacteria are able to cope with the challenges of a sudden increase in salinity by activating adaptation mechanisms. In this study, exponentially growing cells of the pathogen Bacillus cereus ATCC 14579 were exposed to both mild (2.5% [wt/vol] NaCl) and ...

Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation

Angewandte Chemie, EarlyView.
Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...

Identification of a Nonribosomal Peptide Analog With Activity Against Multiple Gram‐Positive Bacteria via a Synthetic Bioinformatic Natural Product Discovery Approach

Advanced Science, EarlyView.
The genome of Rhodococcus erythropolis D‐1 was analyzed by bioinformatic tools to mine a novel nonribosomal peptide synthetase (NRPS) gene cluster. A nonribosomal peptide analog ZURJC5 associated with the NRPS was chemically synthesized. Through structure‐activity relationship studies, ZURJC28 was ultimately obtained and showed antibacterial activity ...

Lipopeptide overproduction by cell immobilization on iron-enriched light polymer particles [PDF]

, 2009
The study concerns surfactin and/or fengycin batch production by immobilized cells of Bacillus subtilis ATCC 21332. Light carriers designed for a three phase inverse fluidized bed biofilm reactor (TPFIBR) were used.

The mechanism of Bacillus subtilis to guarantee the safe utilization of brackish water by improving soil physical properties and cotton production

Agricultural Water Management
Although brackish water (BW) irrigation alleviates freshwater (FW) scarcity in arid regions, it risks soil salinization, deterioration of soil physical properties, and productivity decline.

Spectinomycin dependence in Bacillus subtilis [PDF]

Journal of Bacteriology, 1979
Spectinomycin dependence in Bacillus subtilis involves two mutations, one conferring drug resistance and the other producing a requirement for spectinomycin for growth.

Use of the “Ru‐1O2‐Hydrazide” System Catalyzed by Metallic Ruthenium Complexes to Decipher the Interaction Between Microbes and Host Cancer Cells

Advanced Science, EarlyView.
ABSTRACT The dynamic interplay between bacteria and host cancer cells plays a critical role in tumor microenvironment modulation, bacterial pathogenesis, and potential oncotherapy applications. However, traditional methods often fail to capture transient or spatially restricted molecular interactions at the bacteria‐cancer cell interface.

Bacillus subtilis spo0H gene [PDF]

Journal of Bacteriology, 1984
A 2.8-kilobase fragment of the Bacillus subtilis chromosome containing a functional spo0H gene was cloned by using a modification of the helper system described by T. Gryczan and co-workers (T. Gryczan, S. Contente, and D. Dubnau, Mol. Gen. Genet. 177:459-467, 1980).

Nano‐Backpack Engineered Probiotics with Reactive Oxygen Species–Responsive Tungsten Release for Synergistic Therapy of Inflammatory Bowel Disease

Advanced Science, EarlyView.
An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...
