"The influence of
humic acids of different origins on
the growth of bacterial cultures of different taxa isolated from the soil and the digestive tracts of earthworms (Aporrectodea caliginosa)—habitats with contrasting conditions—was studied.
More than half of the soil and intestinal isolates from the 170 tested strains grew on the humic acid of brown coal as the only carbon source. The specific growth rate of the bacteria isolated from the intestines of the earthworms was higher than that of the soil bacteria. The use of humic acids by intestinal bacteria confirms the possibility of symbiotic digestion by earthworms with the participation of bacterial symbionts.
Humic acids at a concentration of 0.1 g/l stimulated the growth of the soil and intestinal bacteria strains (66 strains out of 161) on Czapek’s medium with glucose (1 g/l), probably, acting as a regulator of the cell metabolism. On the medium with the humic acid, the intestinal bacteria grew faster than the soil isolates did. The most active growth of the intestinal isolates was observed by
Paenibacillus sp.,
Pseudomonas putida, Delftia acidovorans, Microbacterium terregens, and
Aeromonas sp.; among the soil ones were the representatives of the
Pseudomonas genus. A response of the bacteria to the influence of humic acids was shown at the strain level using the example of
Pseudomonas representatives. The
Flexomhumin preparation stimulated the growth of the hydrocarbon-oxidizing
Acinetobacter sp. bacteria. This effect can be used for creating a new compound with the elevated activity of bacteria that are destroyers of oil and oil products."

Welp answered my question; humic, bennies, and sugar is all you need. PEACE.
