The Scientific World Journal, 2012 Cyanide is one of the most toxic substances present in a wide variety of food materials that are consumed by animals. Rhodanese, a ubiquitous enzyme, can catalyse the detoxification of cyanide by sulphuration reaction.

Impact of intestinal microbiota on metabolic toxicity and potential detoxification of amygdalin
Frontiers in Microbiology, 2022 Amygdalin (Amy) is metabolized into cyanide in vivo, which may lead to fatal poisoning after oral administration. The defense mechanisms against toxic cyanide have not yet been adequately studied.

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]
, 1992 Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...

Multiple Forms of Bovine Liver Rhodanese [PDF]
European Journal of Biochemistry, 1981 The heterogeneity of crystalline rhodanese from bovine liver has been studied. The enzyme was separated by preparative disc electrophoresis into four stable forms designated I(3.5%), II(17.0%), III(62.0%) and IV(17.5%). All these components have the same molecular weight of about 35,000 both in native and denaturing conditions.

Genetic diversity of ‘Candidatus Phytoplasma mali’ strains in Poland
Phytopathologia Mediterranea, 2015 During 2010-2013, samples from 267 apple trees growing in six regions of Poland were tested for phytoplasma presence. ‘Candidatus Phytoplasma mali’ was detected in 17 samples from phloem tissue of apple shoots showing typical apple proliferation symptoms.

Biological hydropersulfides and related polysulfides – a new concept and perspective in redox biology [PDF]
, 2018 The chemical biology of thiols (RSH, e.g., cysteine and cysteine‐containing proteins/peptides) has been a topic of extreme interest for many decades due to their reported roles in protein structure/folding, redox signaling, metal ligation, cellular ...

The titration of rhodanese with substrates [PDF]
FEBS Letters, 1974 The transfer of sulfur catalyzed by rhodanese (EC 2.8.1 .l .) is thought to proceed through a double displacement mechanism where the enzyme is first charged with the donor sulfur and then discharged by the acceptor [ 1 ] . Earlier workers have reported that the enzyme accepts from 1 to 1.9 atoms of sulfur per mole of enzyme of mol. wt. of 37 000 (2-4).

Bioleaching Microbial Community Metabolism and Composition Driven by Copper Sulphide Mineral Type
Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.Bioleaching is a microbially mediated green technology for the recovery of metals from ore. Here, microbial consortia from a copper bioleaching column in Cyprus were cultivated on chalcopyrite (CuFeS2) and then sub‐cultured on chalcocite (Cu2S) and chalcopyrite to investigate how mineral type and surface chemistry influence microbial community ...
