Both H2 and formate were formed during butyrate oxidation by Syntrophospora bryantii with pentenoate as electron acceptor and during propionate oxidation by a mesophilic propionate oxidizing bacterium (MPOB) with fumarate as electron acceptor. H2 and formate levels were affected by the bicarbonate concentration. S bryantii and MPOB were also able to(More)
A mesophilic acetogenic bacterium (MPOB) oxidized propionate to acetate and CO(2) in cocultures with the formate- and hydrogen-utilizing methanogens Methanospirillum hungatei and Methanobacterium formicicum. Propionate oxidation did not occur in cocultures with two Methanobrevibacter strains, which grew only with hydrogen. Tricultures consisting of MPOB,(More)
An endoplasmic reticulum-localized tomato omega-3 fatty acid desaturase gene (LeFAD3) was isolated. The antisense tomato plants were obtained under the control of the cauliflower mosaic virus 35S promoter (35S-CaMV). Northern blot analysis confirmed that the expression of LeFAD3 was inhibited in the tomato genome. Levels of 18:3 decreased and(More)
