Abstract
The objective of the research is to produce biofertilizers and Phyto stimulants from human waste by anaerobic fermentation with efficient microorganisms and the addition of lens culinaris. Method The dry fecal mass was treated by anaerobic fermentation using efficient bacteria microorganisms: phototrophic, lactic acid, sawdust, and Lens Culinaris in a medium of pH 5.8 to 7.9 and temperature 22 to 65 ℃. The research level is descriptive and explanatory, with a quantitative approach applied. Results From the bio digestible pathogen-free mixture, biofertilizer with micro- and macronutrients (g/kg) has been obtained: total nitrogen 10.5; NH4 2.03; phosphorus 1.76; potassium 87.5; and the liquid Phyto stimulant containing (ng/g): Indole acetic acid 8.5; gibberellin 7.2; tryptophan 28; auxins 422. Conclusions The pretreatment of samples with calcium oxide, composting with EM at pH 6.6 at 24 ℃, and anaerobic fermentation generated the liquid biofertilizer and bio stimulant in the absence of fecal coliforms (E. coli).
