Environmental factors influencing landfill gas biofiltration: Lab scale study on methanotrophic bacteria growth

Environmental factors influencing growth and pubertal development.

Postnatal growth is based on hereditary signals and environmental factors in a complex regulatory network. Each factor must be in an optimal state for normal growth of the child. Fetal conditions may also have consequences on postnatal height. Intrauterine growth retardation can be recovered postnatally, although postnatal growth remains depressed in about one-third of cases. After birth, the e...

Environmental Control of Methanotrophic Bacteria in Temperate Lakes

Detection of methanotrophic bacteria in environmental samples with the PCR.

We designed PCR primers by using the DNA sequences of the soluble methane monooxygenase gene clusters of Methylosinus trichosporium OB3b and Methylococcus capsulatus (Bath), and these primers were found to be specific for four of the five structural genes in the soluble methane monooxygenase gene clusters of several methanotrophs. We also designed primers for the gram-negative methylotroph-spec...

Environmental factors influencing attenuation of methane and hydrochlorofluorocarbons in landfill cover soils.

The influence of different environmental factors on methane oxidation and degradation of hydrochlorofluorocarbons (HCFCs) was investigated in microcosms containing soil sampled at Skellingsted Landfill, Denmark. The soil showed a high capacity for methane oxidation resulting in a maximum oxidation rate of 104 microg CH4 g(-1) h(-1) and a low affinity of methane with a half-saturation constant o...
