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… Expand
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. Expand
Degradation of Alkanes in Rhodococcus
Alkanes are widely distributed in the environment as they not only constitute the large fraction of crude oil but are also produced by many living organisms. They are saturated hydrocarbons ofExpand

Aerobic cometabolism of 1,1,2,2-TeCA by a propane-growing microbial consortium (C2): Diversity of alkane monooxygenase genes and design of an on-site bioremediation process
TLDR
The feasibility of an on-site TeCA bioremediation strategy with C2 was evaluated by simulating a continuous-flow aerobic co-metabolic process with different bioreactor configurations and results show that the configuration with a suspended-cell continuous stirred-tank reactor (CSTR) followed by a suspend-cell plug-flow reactor (PFR) was the one giving the best performance with consortium C2.
