Variation among Desulfovibrio Species in Electron Transfer Systems Used for Syntrophic Growth

Abstract: bMineralization of organic matter in anoxic environments relies on the cooperative activities of hydrogen producers and consumers linked by interspecies electron transfer in syntrophic consortia that may include sulfate-reducing species (e.g., Desulfovibrio). Physiological differences and various gene repertoires implicated in syntrophic metabolism among Desulfovibrio species suggest considerable variation in the biochemical basis of syntrophy. In this study, comparative transcriptional and mutant analyses of … Show more

“…Sulfate reducing bacteria, such as Desulfovibrio and Syntrophobacter spp., were also abundant in many of the UASB reactor samples. Both of these genera are capable of switching between sulfidogenic and syntrophic lifestyles (Meyer et al, 2013). Syntrophobacter species were abundant in twelve granular samples out of fourteen and accounted for 0.64-15.8% of the total community.…”

“…Desulfovibrio species can grow syntrophically by producing H 2 or formate as interspecies electron carriers (Meyer et al, 2013;Walker et al, 2009). The addition of carbon cloth did not accelerate the metabolism of a co-culture of D. vulgaris and G. sulfurreducens.…”

“…Also, during syntrophic growth, a similar role of the periplasmic hydrogenase, acting as an H 2 -producing enzyme, was observed in D. vulgaris Hildenborough cultures grown in lactate with a hydrogenotrophic methanogen (8). Furthermore, also in Desulfovibrio alaskensis G20, the HynAB hydrogenase seems to be the main enzyme responsible for H 2 production during syntrophic growth (12).…”

“…In addition, the expression patterns of different hydrogenases were shown to be different and to depend on the substrate, fermentative or respiratory growth, or metal availability (5,(7)(8)(9)(10)(11)(12)(13). Furthermore, the function of each hydrogenase in terms of hydrogen production or oxidation may vary depending on the conditions presented to the cell.…”
