Chirality Sensing of Amino Acid Esters by S-2-Methylbutanamido-Substituted m-Phthalic Diamide-Linked Zinc Bisporphyrinate

Molecules
To understand the role of an additional coordination site in the linker in chirality sensing, we designed and synthesized an S-2-methylbutanamido-substituted m-phthalic diamide-linked zinc bisporphyrinate, [Zn2(S-MAABis)] and investigated its ability to ...

Decoding Biothreats With FT‐ICR‐MS: Metabotyping of Bacillus cereus Spores Through Untargeted Metabolomics

Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.
ABSTRACT Genome sequencing is the gold standard for microbial identification. However, it fails to distinguish closely related species with overlapping genetic features. This is the case of Bacillus cereus and Bacillus cytotoxicus, two members of the B. cereus group with distinct pathogenic profiles. While B. cereus, a well‐known opportunistic pathogen

Integrated Kinetic and Transcriptomic Insights Into Nano‐Assisted Tandemol Biodegradation by UV‐Mutagenized Pseudomonas synaxantha rhizo‐25

Journal of Basic Microbiology, Volume 66, Issue 7, July 2026.
ABSTRACT This study assesses the kinetics of Tandemol lubricant degradation by Pseudomonas synaxantha rhizo‐25 after UV treatment and nanoparticle inclusion. The degradation efficiency was assessed in terms of the Total Petroleum Hydrocarbons (TPH) and aromatic compounds degraded in a liquid medium containing Tandemol lubricant.

Potential for Biodegradation of Phthalic Acid Esters in Marine Regions [PDF]

Applied and Environmental Microbiology, 1981
Di-(2-ethylhexyl) phthalate was the major phthalic acid ester in the Mississippi River estuary, with mean levels of 0.1 μg/g (dry weight) in surface sediments, 1.0 μg/liter in river water, and 0.7 μg/liter in delta water. Bacteria that grew aerobically on dibutyl phthalate and o -phthalic acid were readily detected ...
