Ok so far I came up with another lead. This is a lil bit from instructions for a product called GeoEM-B
http://www.geocarebiotech.com/eng/geoem-b/
"Step 3: Bacteria expansion liquid
Use 100~200L clean water mix with 1~2kg GeoEM-B plus 0.2% milk powder and 3% molasses. Aerating the mixture for 24~48hours. (we suggest to use aquarium aerator in helping aeration, if you don’t have one, please manually stir the mixture to increased contact with the dissolve oxygen in the air. Stir for 15 minutes every 2~3 hours each day, 3~4 times a day will be best.) Dilute 1:10 bacteria expansion liquid and pour to the soil root, or assist with organic fertilizer and spray on the soil before the plowing. Apply on short-term crop once a season; and expand bacteria 2~3 times a year for the long-term crop."
Now this is the composition of the product that they are using in step 3 above.
【Composition】
Each gram contain above 1.25 x 108 ecological beneficial bacteria:
Actinomycetes
Yeast
Subtilis bacteria
Lactic acid bacteria
Phosphate-solubilizing bacteria
Nitrogen-fixing bacteria
Protein/fiber-decomposing bacteria
Mycorrhizal fungi group
Rhizosphere flora protection
So you can see where I am going with this to determine if Powdered Milk is safe for Mycorrhizal fungi. Whats your thoughts?
