Here's a reply to Richard Stanley's post on yeast from Joshua Guinto, the accompanying .pdf was too large to propagate on [stoves] so here is the post by itself as I cannot shrink a pdf.
AJH Hi Richard This is to confirm and reinforce your research on the use of yeast for decomposition. We (with the Save the Children, the family participants and the CabioKid Foundation) have just gone through a two day training on the production of Natural Fertilizers and Pesticides held in the town of Hagonoy in province of Bulacan. We did a lot on making natural fertilzers but the most interesting part of all those is the use of YEAST for the fermentation of the organic matter. Yeast, according to the procedure we learned is best in anaerobic condition. Here is part of the recipe for making fermented plant jiuice (FFJ) 1 kg sweet potato or kangkong leaves 1 kg leaves of nitrogen fixing plants 1 kg leaves of narra tree 1 kg leaves of neem tree 4 bote ng beer OR BETTER YET 8 tables spoons YEAST, because yeast is cheaper 4 kilong molasses pail with cover CabioKid Foundation is working to promote sustainable communities with permaculture at its core. You may see their website at www.cabiokid.org. The procedure went on in providing alternative to YEAST. And that is the use of INDIGENOUS MICROORGANISMS (IMO). They are the kind of good fungus that may be harvested from the gardens or the forests. Rice is cooked in natural fire, in earthen jars, filled into clay jars or fresh bamboo tubes, covered with brown paper tightly and set in the forest or garden for 14 days. Good fungus will inoculate the rice. They are the white or yellow. the black or any other color is a bad fungus. This fungus (not yet clear to me the scientific name) is further diluted to molasses or brown sugar to multiply their population. This concoction may be used as an alternative to yeast. It may also be used to speed up composting and then combat bad microorganisms in the garbage pile, in the toilets and even used in animal feeds to promote better digestion. Amazingly, animal farms using this concoction are satisfied in having odorless feces and healthier and heavier animals even without cleaning their barns. I suppose the microorganisms in the IMO are the beneficial ones (probiotics) in the soil such as the azotobacter, tne mychorriza, the rhizobium, actinomycetes and many more. The concept is to harvest the beneficial organisms, bring them into a powerful combination and numbers so they may be able to combat the bad organisms. This technology (and system) has its roots from South Korea. There is a debate, however against this coming from the scientists of the Bureau of Soils... on the grounds of efficacy. The scientists in the government department wants to unpack the mechanisms why these series of concoctions are effective. But the procedure is so simple and doable and effective and low cost that it has now spread in the entire country among the practitioners of organic/natural farming without waiting for the laboratory tests of the bureau. I have enclosed here another document coming from an Alliance of the organic farmers from the province of Pangasinan It is my native language, Pilipino. But you may deduce what it says from the nice drawings. This document is many years old back and prescribes the use of beer. But women complain against the cost of beer.... and about men drinking it ahead of the fermentation project. Recently, yeast came in the picture... and IMO as fermentation agents. Hopes this boosts your research. I will soon do this myself during our training on stoves and holey briquettes in Bulacan sometime in January 2013.
