Web1 mei 2009 · An additional factor, however, may be the contribution of metabolic crossfeeding from other active polysaccharide-metabolizing bacteria, leading to stimulation of butyrate producers. This effect has been demonstrated to occur in in vitro cocultures between bifidobacteria and butyrate-producing species. WebObviously, metabolite cross-feeding promoted NADH production and electron transfer, resulting in efficient SMX biodegradation by Pd and So in the presence of nitrate. Its feasibility was finally verified by the coculture of an activated sludge denitrifier and So. crystal store coquitlam
