You may be on to something there. I should not be difficult to grow any bacterium, as long as you provide the right conditions. An aquarium aerator and some molasses (for quick nutrition) might be two easy additions to improve the growing environment.

Below is a link to a scholarly article about culturing the bacterium for use in agriculture (South African avocado growing). I did not bother reading it, but it should provide more than enough detail on how to do it.

What else have you tried? Sulfur could be a less expensive alternative. The main problem with culturing your own is the fact you're also culturing who knows what else, up to and including Legionaires' disease.

I agree with pasadena that there might be another easier solution to your soil problems... however, I don't really see a problem with what you're trying. I'm sure glad that not everyone in history has been scared to culture bacteria, otherwise we'd have no sauerkraut, yogurt, bread, soy sauce, pickles, beer, wine, etc...

Also, nobody has shown any problem with culturing compost tea, which is a real shot in the dark (put some partially finished compost in some water and aerate for a few days, then spray on the plants and soil) compared to this.

Hi,

Do you use drip systems to water your plants? In the heat of summer here in zone 9 Riverside and the short fall and short cold winter the white fungus is kept under control by carefully regulating the water and where the water goes.

Sometimes turning in the bark helps. Usually it is to much bark. Using shredded leaves or a walk on bark mixed with the shredded leaves helps control the white stuff.

Have you treated the leaves? I'd stay away from making my own uncontrolled bacteria factory. I'd try changing your mulching medium and how thick you mulch.

Hope this helps.
