One technique in culturing other beneficial microorganism is getting them fro your local aged forest. One way is finding a healthy old robust tree in your local forest. Check the humus litter around the tree. The tree should have accumulated real deep humus, litter, compost of at least 2 feet to 1 yard deep. In this area through observation, we can deduce that soil fertility and microbial biodiversity are high. Our goal is to trap and culture these diversed, aged beneficial indigenous microorganisms. The technique that we use in trapping these microorganisms is the use of carbohydrate like cooked rice. Microorganisms will be attracted to food. So generally, what we do is to put the cooked rice on a flatter container with lid. For example, you can use a plastic lunch box and add about an inch of cooked rice allowing air space in the container. What is important here is a larger area to trap those microorganisms. It is suggested that you cover this container with metal netting or equivalent protecting it from animals like rats that may undig your container once you bury it in the litter, humus of your local forest. In 2-10 days (relative to temperature), you may undig your container and will notice contamination of microorganisms like white and other color molds on the cooked rice. The cooked rice has been infected now with microorganisms of your local forest. The next step is to add 1/3 amount of crude sugar or molasses to the infected cooked rice. After a week, the concoction will look like sticky, liquidy rice. You may then add equal amount of crude sugar or molasses to keep it for storage, arresting microbial activities, in a cooler area. To use, you may dilute this serum with 20 parts water. This diluted form shall then serve as your basic forest microorganisms. You may strain it and put in a container.
Another version of trapping similar forest microorganisms is simply getting the litter, humus and spreading them sparingly to the top your cooked rice. Forest leaf molds can also be used. The same procedure will be followed as described in the culture of local forest microorganisms.
Another method of gathering microorganism is through burying your container with cooked rice on bamboo plants litter. Apparently, bamboo through observation and experience in the East, attracts powerful beneficial microorganisms as the roots of the bamboo exude sugary substances that attract beneficial microorganisms. The same procedure is followed as described before in its culture.
Plant Specific Microorganisms
An equal specific method is trapping beneficial microorganisms of specific plants you want to grow or growing. For example, if you want to trap and culture beneficial microorganisms from rice, you should then select healthy, vigorous rice plant, cut them and put inverted cooked rice container over the cut rice plant. Again, beneficial microorganisms specific to rice will be attracted to the cooked rice. You can use this technique to any other plant of choice and the same procedure of culture will be used as previously described.
Rhizobium Nitrogen-Fixing Bacteria
One of the most popular nitrogen-fixing bacteria is rhizobium. It is amazing that when we coat our legumes with these specific bacteria, legumes grow well and more nitrogen is fixed on the soil. Amazingly enough, basic culture of these beneficial bacteria is simple. Once we have seen those nodules created by the bacteria fixing nitrogen on the roots of the legumes, we can assume that there are lots of these rhizobia and nitrogen fixed. Just pull out the legumes plants on a very specific stage, especially towards their flowering/fruiting stage. A simple method of culture is simply get the soil with these leguminous bacteria and mix with crude sugar with equal ratio of crude sugar. Rhizobium bacteria will proliferate feeding on the sugar and thus can be mixed with your next batch of legume seeds for inoculation. Our concoction or recipe of beneficial indigenous microorganism (BIM) is 50% lactic acid bacteria and the rest is 50% of the other microorganisms cultured. So you may use 1part forest microorganism, 1 part bamboo microorganism and 1 part specific plant microorganism mixed with 3 parts or 50% lacto bacilli. The more diversed microbes, the better. However, we will still use 50% of the total beneficial indigenous microorganisms to be lactic acid bacteria. The rest you can experiment and make your own observations and formulations. I cannot really tell you specifically what microbes we get from the different sources we have mentioned. As a rule, I only use the above BIM for plants. For animals, I use just pure lacto bacilli for we have isolated this as described. We have used the bamboo microorganisms for fermenting feeds to be fed to animals.
Different type of microorganisms thrive on different type of foods. As you can see, we use principally carbohydrates and sugars. But it will be equally important that we provide these beneficial indigenous microorganisms with other nutrients. In fact, we mix or add fermented plant extracts (fermented plant and fruit juices), ginger-garlic nutrients, brown rice vinegar and fish amino acid. That’s why in most instances, we mix these beneficial indigenous microorganisms with bionutrients to make it more effective.
