Establishment of hydrogen-utilizing bacteria in the rumen of the newborn lamb

FEMS Microbiology Letters (1994)

B. Morvan JoÃ l Dore FranÃ§oise Rieu-Lesme LoÃ ̄c Foucat GÃ©rard Fonty

The development of hydrogenotrophic bacteria in the rumen of lambs was investigated by culture and labeling experiments. 14CO2 and 13CO2 incorporation by the rumen microflora of a 24-h-old lamb showed that while there was no labeled methane, double-labeled acetate was formed indicating the presence of hydrogen-dependent acetogenesis. In vitro counts from rumen fluid of 20-h-old lambs confirmed an extensive colonization of acetogenic bacteria while methanogens were absent. Methanogens appeared in the rumen of 30-h-old lambs, and as they developed there was a proportional decrease in the numbers of acetogens, indicating a competition for hydrogen between these two groups. Hydrogen-utilizing sulfate-reducing bacteria, which were established by the 3rd day after birth, did not seem to be affected by this competition.

A new H2 / CO2-using acetogenic bacterium from the rumen: Description of Ruminococcus schinkii sp. nov.

FEMS Microbiology Letters (1996)

F. Rieu-Lesme B. Morvan Matthew Collins Gérard Fonty Anne Willems

Two strains of H2 / CO2-using acetogenic bacteria were isolated from the rumen of suckling lambs. Both strains displayed a coccobacillar morphology and possessed a Gram-positive type cell wall. Numerous organic substrates, including some O-methylated aromatic compounds, were used heterotrophically. 16S rRNA gene sequencing demonstrated that the two acetogenic isolates were phylogenetically identical and represent a new subline within Clostridium cluster XIVa. Based on phenotypic and phylogenetic considerations a new species, Ruminococcus schinkii sp. nov., is proposed.

Enumeration of H2-utilizing methanogenic archaea, acetogenic and sulfate-reducing bacteria from human feces

FEMS Microbiology Ecology (1995)

Fecal specimens from 19 healthy humans were used to enumerate H2-utilizing microbial populations of methanogenic archaea (MA), acetogenic bacteria (AB) and sulfate-reducing bacteria (SRB). Eight subjects were methane (CH4) excretors (CH4+) and 11 non CH4-excretors (CH4−), based on breath methane concentrations. The mean ± S.E. of the logarithm of MA per gram wet weight feces were 8.8 ± 0.21 and 2.6 ± 0.39 for CH4+ and CH4−, respectively (P < 0.001). SRB counts were 7.1 ± 0.43 and 7.3 ± 0.39, respectively (NS), while counts of AB were 4.6 ± 0.75 and 6.6 ± 0.38, respectively (P < 0.02). Counts of AB were negatively correlated with counts of MA (r = −0.53; P < 0.05). These results confirm the potential importance of AB in the human colon, especially for CH4— subjects, and suggest that a much greater competitive interrelation occurs in the human colon between MA and AB than between the former and SRB. We further report on the isolation of representatives of the dominant acetogenic population. Three strains from two CH4— subjects were characterized from 10−5-10−7 dilutions. They all consumed and several carbohydrates to produce acetate as the sole metabolite. Phenotypically related to the species Peptostreptococcus productus, the strains used H2/CO2 via the acetyl-CoA pathway.
