Chloroform (CF) is largely produced by both anthropogenic and natural sources. It is detected in ground and surface water sources and it represents the most abundant halocarbon in the atmosphere. Microbial CF degradation occurs under both aerobic and anaerobic conditions. Apart from a few reports describing the utilization of CF as a terminal electron acceptor during growth, CF degradation was mainly reported as a cometabolic process. CF aerobic cometabolism is supported by growth on short… 
Anaerobic Biodegradation of Chloroform and Dichloromethane with a Dehalobacter Enrichment Culture
TLDR
The results demonstrate the potential to achieve full dechlorination of CF and DCM to nonhazardous products that are difficult to identify in the field and the reducing power gained from oxidation was shown to support reductive dechlorinated CF to DCM.
Metagenomic- and Cultivation-Based Exploration of Anaerobic Chloroform Biotransformation in Hypersaline Sediments as Natural Source of Chloromethanes
TLDR
Application of interdisciplinary approaches of microbial cultivation, stable isotope labelling, and metagenomics aided in defining potential chloroform transformation pathways and indicates that microbiota may act as a filter to reduce CF emission from hypersaline lakes to the atmosphere.
Degradation of Alkanes in Rhodococcus
TLDR
Because of their long-term survival capacity, broad catabolic abilities, and effective contact mechanisms with hydrocarbon molecules, alkanotrophic Rhodococcus strains have biotechnology applications and potential in bioremediation and biotransformation reactions.
Biovalorization of food wastes by anaerobic acidification processes
Biodegradation is an eco-friendly option for the disposal and recovery of organic waste, including food waste (FW). These residues can be treated and recovered through anaerobic digestion processes,

Cometabolic Degradation of Anti-Inflammatory and Analgesic Pharmaceuticals by a Pentane Enrichment Culture
Pharmaceutically active compounds (PhACs) are common contaminants found in surface and groundwaters, often due to their inefficient removal from wastewater treatment plants. One way in which these
Biodegradation of Volatile Organic Compounds and Their Effects on Biodegradability under Co-Existing Conditions
TLDR

Complete chloroform dechlorination by organochlorine respiration and fermentation.
TLDR
It is reported for the first time a microbial community capable of complete CF dechlorination by metabolic processes, and the proliferation of Dehalobacter was linked directly to both the dehalorespiration and dehalofermentation processes.
Chloroform respiration to dichloromethane by a Dehalobacter population.
TLDR
It is discovered that CF was rapidly and sustainably dechlorinated in the course of investigating anaerobic reductive dechlorination of 1,1,1-trichloroethane in a Dehalobacter-containing culture, with widespread implications for bioremediation.
Riboflavin- and cobalamin-mediated biodegradation of chloroform in a methanogenic consortium.
TLDR
The results taken as a whole suggest that the anaerobic bioremediation of CF-contaminated sites can greatly be improved with strategies aimed at increasing the concentration of redox active vitamins.
Aerobic biodegradation of the chloroethenes: pathways, enzymes, ecology, and evolution.
TLDR
This review will summarize the current knowledge of the physiology, biodegradation pathways, genetics, ecology, and evolution of VC- and cDCE-assimilating bacteria, suggesting that they are widespread and influential in aerobic natural attenuation of VC.
Transformation capacities of chlorinated organics by mixed cultures enriched on methane, propane, toluene, or phenol
TLDR
Among the four tested cultures, the resting cells of methane oxidizers exhibited the highest transformation capacities (Tc) for TCE, CF, and 1,2‐DCA, which was observed to be inversely proportional to the chlorine carbon ratio (Cl/C).
Anaerobic Biotransformation of High Concentrations of Chloroform by an Enrichment Culture and Two Bacterial Isolates
TLDR
DHM-1 was capable of growing on corn syrup in the presence of high concentrations of CF (as may be present near contaminant source zones in groundwater), which makes it a promising culture for bioaugmentation.

Biodegradation of chloroform (CF) was examined in a methanogenic enrichment culture grown on dichloromethane (DCM) as the sole organic carbon and energy source, with and without the addition of

Abstract Aerobic cometabolism of chloroform (CF) and 1,1,1-trichloroethane (1,1,1-TCA) was observed by subsurface microorganisms grown on butane. Studies performed in batch incubated microcosms were
