well im no scientist but my knowlege of yeast, like brewers yeast you can uy commercialy is marketed as a protien, and protien is consumed for its Nitrogen. Any bacteria would love to chomp on some yeast. To my knowledge bacteria dont have 1 prefered food source. You reference nitrifying bacteria but that is only a couple of them and they are nitrogen fixating, meaning they take the nitrogen from the air or atmosphere and render it to the plant, who couldnt accomplish this on it own.Yeah, reference please or evidence on ferments being nitrifying bacteria friendly. It would seem protien or carbohydrates varying from simple glucose to polyscacchrides seems to enhance microbe growth. And with a fast growing annual I only want certian cultures in my mix.
No comment on earth juice, MSDS lists "sea kelp, sugarcane molasses, oatbran, yeast" as primary ingredients.
I could see yeast being a potential food source itself for nitrifying bacteria as a food source like "bakers yeast" however it seems to be an odd way of approching it. Dead yeast is a food source for live yeast, so I assume microbes could use it.
I just thought it seems odd to use lacto or yeast to bump up microbe activity because they seem to supress microbe activity as in the case of fermented alcohol or pickling process .. I could see yeast also "limiting" excess simple carbohydrates but not to big a fan of the idea of it competing with mineralizing bacteria especially with exudates in the rhizosphere.
If anything I'm referencing Jeff Lowenfells and Dr Inghams work on microbes.. the majority of the AG products I've seen seem to focus more on aerobic bacteria that mineralize vs anerobes...
If it works for you.. cool.. I'm just trying to think out loud how this ferment style composting can be used.
As far as lactio bacillus is concerned im not sure where the hang up is. They dominate in their perfered pH range of 3-4. Thats a far cry from a plants prefered or at least any plant i have ever grown. I think research is required by parties who wish to dive into this, as im sure the actual web sites can say it better than i can. But to give you and idea Ill say i have 1 5gal bucket of pure water. It reads 5.4pH. Thats not ideal for cannabis or most plants in soil. Hydro s another story. The amount of lactic bacteria or even a DIY fermented fertilizer is very minimal. 1 tsp/gallon. Thats going to drop your pH even more now since lactic bacteria and yeast and purple sulfer bacteria are a HIGH ACIDITY favoring. But why on earth would you ever hand water a plant with a pH lower than 6.5? , so you must re adjust the pH. So add the pH up and stabalize it.
Once added to a new enviroment where aerobes are proliferating the FLACULATIVE ANEROBES can still be of benifit but they dont have a front row serat to the show like the aerobic microbes. Lactic bacteria are exellent composters FACT. http://www.infrc.or.jp/english/KNF_Data_Base_Web/PDF KNF Conf Data/C1-5-018.pdf
Next is the phototropic bacteria FACT. http://www.biologyexams4u.com/2013/03/difference-between-plant-photosynthesis.html
