Abstract

The study was conducted at the Biochemistry Engineering Laboratory of the Federal University of the Rio Grande do Norte to verify the efficacy of microorganisms as solvents of apatite and biotite rock powder to enable the availability and rapid production of biofertilizers. Bacteria Paenibacillus polymyxa, Ralstonia solanacearum, Cromobacterium violaceum and Acidithiobacillus thiooxidans and fungi Penicillium fellutanum and Tricoderma humatum were inoculated into biotite rock powder and apatite rock powder originating from the States of Paraíba and Paraná, respectively, in Brazil. Rock powder samples were taken on Petri plates, 10% sulfur was added to each, and were subsequently inoculated and co-inoculated for a period of 72 days. Every 12th day, the samples were withdrawn and their mineral release curve was studied. From our results, the co-inoculations with Paenibacillus polymyxa + Ralstonia solanacearum and Paenibacillus polymyxa + Cromobacterium violaceum rendered higher solubility of K and P, respectively, at 36 days.
