Fig. 2.20 Relative number and distribution of bacterial (a) and archaeal (b) proteins in different
stages of the SHPT process, based on taxonomic bins for proteome-derived proteins with taxonomic
annotation. Distributions in c and d are at the level of classes within the phyla Proteobacteria and
Firmicutes, respectively. e Is at the level of the orders within the Euryarchaeota (Jia et al. 2017b)
of pyruvate dehydrogenase; (ii) dihydrolipoamide dehydrogenase; (iii) pyruvateferredoxin/flavodoxin oxidoreductase; (iv) formate C-acetyltransferase; and (v)
acetyl-CoA synthetase, as displayed in Fig. 2.22. The E1 component of pyruvate
dehydrogenase found in Stage II and involved in pyruvate metabolism, is able to
change pyruvic acid into acetyl-CoA and CO 2 and stems from Escherichia. The
dihydrolipoamide dehydrogenase appears in the decarboxylase pathway of pyruvic acid for biohydrogen production belonging to Pseudomonas and Zymomonas in
Stages II and III, separately. Pyruvate-ferredoxin/flavodoxin oxidoreductase which
is found in Pelosinus and Kluyvera bacteria in Stage I is a critical enzyme for the
equivilibrium regulation of NADH/NAD
+ in hydrogen production. These results
indicated that although these identified proteins belonged to disparate genera, they
probably can happen simultaneously with biogydrogen production together. This
pathway contains non-native hydrogenase linked with NAD(P) and H 2 generation
from NAD(P)H provided rapidly from glucose degradation via the pentose phosphate pathway. Formate C-acetyltransferase (pyruvate formate lyase, PFL) belongs
