Catalytic Activity of Optimized Environment and MicrobialConditions on Bioleaching of Leonardite for Bio-Humic Production

Abstract

The potential use of Leonardite for organic farming is common in worldwide but due to standart chemical production process of humicacid from Leonardite ore, the humic acid usage in organic farming is forbidden. Here we present a new optimized method for biologicalhumic production via using a combination of biotechnological and conditional processes. This study includes two phases. Initially, thecollection of Leonardite ore samples from different Leonardite deposites of Turkey and the determination the most qualified ore bed viausing FTIR spectroscopy and SEM view results. Due to the results, the best ore was determined from Adana-Tufanbeyli province. Inthe second phase, the samples were taken from Adana-Tufanbeyli province for bio-humic production via using several bioleachingprocess to find the best condition for maximum production of bio-humic. California method was used as standart method to determinethe leaching ratio. As an initial of bioleaching process, several leonardite ore ratios were determined in the prepared bacteria basedsolution then under different temperature, time conditions, the productivity effect of pH parameters were tested to find the optimumleaching standarts for bio-humic production. The optimized conditions were provided 23.08% bio-humic leaching ratio. This resultshows us there is a better potential of extraction of humic acid via biotechnological methods compared with the conventional methods.Since there is a restriction of usage of humic acid in organic farming due to its chemical production process, this study opens a new wayof usage of humic in biologic form in organic farming and with this high leaching potential there can be many studies can be done andnew microorganism isolations can be tested with the innovative process of the study. This eligibility of this process to produce humicin biologic form provides an innovative input for organic farming as bio-humic with this study.
