The commercial availability of next generation sequencing (NGS) technologies facilitated the assessment of functional groups of microorganisms in the environment with high coverage, resolution, and reproducibility. Soil methylotrophs were among the first microorganisms in the environment that were assessed with molecular tools, and nowadays, as well with NGS technologies. Studies in the past ye...

Methanol is often considered as a non-competitive substrate for methanogenic archaea, but an increasing number of sulfate-reducing microorganisms (SRMs) have been reported to be capable respiring with methanol electron donor. A better understanding the fate in natural or artificial anaerobic systems thus requires knowledge dissimilation by SRMs. In this study, we describe growth kinetics and su...

Methanol is responsible for a life-threatening poisoning. Fomepizole, a potent alcohol dehydrogenase inhibitor, is an efficient and safe antidote that prevents or reduces toxic methanol metabolism. Although no study has compared its efficacy with ethanol, fomepizole is recommended as a first-line antidote. Treatment should be started as soon as possible, based on history and initial findings in...

This method for the specific determination of methanol in serum is based on the following two reactions: (formula; see text) Alcohol oxidase is not specific: it converts all lower alcohols to their corresponding aldehydes; however, formaldehyde dehydrogenase is specific and thus the transformation of NAD+ to NADH (which is used to monitor the reaction) proceeds only if methanol is originally pr...

Data presented in this paper describe how the percentage decomposition of the catalase-H202 intermediate by methanol and ethanol as determined from absorbance changes (660 to 640 nm) through a lobe of the perfused rat liver can be used to calculate the intracellular ethanol concentration. Values obtained were similar to those measured in the eftluent fluid from the liver. Using this technique, ...

Alcohol metabolism via alcohol dehydrogenase (ADH) and catalase was studied in perfused rat livers by measuring the oxidation of methanol and butanol, selective substrates for catalase and ADH, respectively. In livers from fasted rats, basal rates of methanol uptake of 15 +/- 1 mumol/g/h were decreased significantly to 8 +/- 2 mumol/g/h by addition of butanol. Concomitantly, pyridine nucleotide...

Allium sacculiferum Max. (ASM) is a perennial plant of the Liliaceae family and grows over the entire regions of Korea. Obesity is a serious health problem worldwide and has currently become a prevalent chronic disease. Adipocytes produced by preadipocyte differentiation during adipogenesis and adipocytes combined with abnormal accumulation cause obesity. Recently, intracellular reactive oxygen...

The utilization of methane, a potent greenhouse gas, is an important component of local and global carbon cycles that is characterized by tight linkages between methane-utilizing (methanotrophic) and nonmethanotrophic bacteria. It has been suggested that the methanotroph sustains these nonmethanotrophs by cross-feeding, because subsequent products of the methane oxidation pathway, such as metha...
