FIGURE 5

Composition of essential and conditionally essential amino acids in the biomass of the combined methane oxidizing bacteria (MOB) and hydrogen oxidizing bacteria (HOB) cultures as well as individual MOB and HOB strains. The amino acid content is presented in g/100gproduct, taking into account 5% of moisture (Chemical Composition 1-Unibio, 2021). The amino acid composition of common food and feed ingredients are presented for comparison (in g/100gproduct). Essential amino acids: histidine, lysine, phenylalanine, threonine, valine, leucine, isoleucine; Conditionally essential amino acids: glutamine, glycine, proline. Methionine, cysteine, tyrosine, and tryptophan are not included in this graph, since they are (partially) destroyed during acid hydrolysis. MOB 5 and MOB 6 were not included due to poor data quality. The glutamine content of the food and feed ingredients was not reported in the respective references. The full dataset can be found in the Supplementary Tables S6, S7.
