Solubility curve of rock powder inoculated with microorganisms in the production of biofertilizers

Valeria Nogueira da Silva, Luiz Eduardo de Souza Fernandes da Silva, Apolino Jose Nogueira da Silva, Newton Pereira Stamford, Gorete Ribeiro de Macedo 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 ...
