Methyl-coenzyme M reductase (MCR) catalyzes the methane-forming step in methanogenic
archaea. The active enzyme harbors the nickel (I) hydrocorphin coenzyme F-430 as a …

Microbiological formation of methane has been occurring naturally for ages in such diverse
habitats as marshes, rice paddies, benthic deposits, deep ocean trenches, hot springs, trees …

Microbial biochemistry has recently entered a new and interesting phase. Catabolic
pathways are being reported for the biodegradation of complex organic compounds some of …

The concept proposed by Woese and associates in the late 1970s reclassified all living
organisms into three primary kingdoms: eucaryotes, eubacteria, and archaebacteria (127 …

This Handbook on Metalloproteins focuses on the available structural information of proteins
and their metal ion coordination spheres. It centers on the metal ions indispensable for life …

Following the chemical synthesis of vitamin B12, a search was begun for a potentially
biomimetic “dark” variant of the photochemical A/D‐secocorrin→ corrin cycloisomerization …

Nickel, atomic no. 28, constitutes 8.5% of the earth's core and about 0.008% of the earth's
crust (139). Average worldwide nickel concentrations have been estimated to be 1.0, g/kg for …

Stimulatory, inhibitory and antagonistic roles of heavy metals in anaerobic digestion are
reviewed. Partitioning and speciation, variety of biotic and abiotic detoxifying mechanisms …

Methanobacterium thermoautotrophicum was grown on a mineral salts medium in a
fermenter gassed with H 2 and CO 2, which were the sole carbon and energy sources …
