In the hydrogenosome of anaerobic fungi, the metabolic pathway was also stimulated as revealed by increased acetate production.
However, the metabolic pathway of anaerobic fungi, especially in the presence of methanogens, needs to be further investigated in the cytosol as well as in the hydrogenosome.
Produced pyruvate is transported to the hydrogenosome and metabolized to formate and acetate (Akhmanova et al.
The anaerobic fungi are amitochondrial organisms and have a hydrogenosome instead for energy production (Yarlett et al.
Their thinking stems in large part from recently gathered information about the ancestry of the hydrogenosome.
In contrast, host cells remaining in an anaerobic environment provided the opportunity for the endosymbiont to shed its aerobic metabolism and become a hydrogenosome.
Instead, images of loriciferan tissue reveal what look like hydrogenosomes, organelles that help power some known anaerobic single-celled creatures.
Some one-celled creatures depend on such organisms to take the hydrogen, along with other products, from the hydrogenosomes and turn it into user-friendly metabolites for the host cell (SN: 4/18/98, p.
The facts that mitochondria and hydrogenosomes are aerobic and anaerobic homologues of the same endosymbiotically derived organelle (54) and moreover mitochondria is an organelle in living anaerobic life forms could also support the reconstruction based on the evoecotoxicology approach that mitochondria probably evolved from anaerobic to aerobic metabolism in eukaryotic organisms.
Trichomonas hydrogenosomes contain the NADH dehydrogenase module of mitochondrial complex I.
Mitochondria and hydrogenosomes are believed to be aerobic and anaerobic homologues of the same endosymbiotically derived organelle (Hrdy et al.
