Protein Hydrolysate Biostimulant

Anybody heard of this? It's in some soil additives in the cannabis cultivation industry. I'm not an advanced mycologist but this seemed an advanced question. I've noticed that many things that are good for growing plants, in soil, are good for fungi as well.
Asking because I have some. Below are some snips from a piece at the National Institute of Health. At the bottom is a link to scholarly articles linking these compounds to beneficial mycorrhizal activity.
THANKS!
"Plant-derived protein hydrolysates (PHs) have gained prominence as plant biostimulants because of their potential to increase the germination, productivity and quality of a wide range of horticultural and agronomic crops. ... Moreover, the beneficial effects of PHs also could be due to the stimulation of plant microbiomes."

POSSIBLY RELEVANT SNIPS
Moreover, the use of these compounds as seed treatments can provide additional benefits, such as the reduction of dust formation and prevention of microbial inoculant detachment from the seed surface during handling. The adhesive properties of PHs are primarily related to the ‘sticky’ small cationic peptides. A recent patent (n. 201531523/3 presented on October 22, 2015) proposed by Agrotecnologías Naturales SL (Tarragona, Spain) showed that a soybean-derived PH was able to more than double the number of polyethylene microspheres (having 75 – 90 μm of diameter, and used as substitute for arbuscular mycorrhizal fungi spores) that stuck to the seed surface of wheat (Triticum aestivum L.), corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] in comparison with water. Moreover, mechanical vibration of coated seeds, showed that adding the soybean-derived PH to the microsphere/water suspension increased the adhesion strength of the microspheres by about 96, 36, and 21% in wheat, corn and soybean seeds, respectively.
[...]
These studies provide evidence that PHs can modify microbial community structure and activity, and such changes could contribute to some of the beneficial effects observed after applying these products. Moreover, they provide tantalizing support for the hypothesis that these products could someday be specifically formulated to support beneficial plant-microbial relationships and further enhance plant productivity. In support of this hypothesis, Rouphael et al. (2017a) recently demonstrated that tolerance to alkalinity and salinity of lettuce plants could be improved by combining a PH with a microbial-based biostimulant containing Rhizophagus intraradices (an arbuscular mycorrhizal fungus, AMF) and Trichoderma atroviride (a filamentous fungus that functions as biocontrol agent). The effect of the combined application of the PH and fungi on plant growth was attributed to several factors, including increase in root surface area, greater chlorophyll synthesis and proline accumulation.

Yeah. Not suggesting that. Perhaps some different rhizomorphic activity... :-)
