| Sumario: | This research demonstrated the possibility to use a secondary product of paper industry (BIODAC 12/20) as carrier of microorganisms. The BIODAC granules showed high porosity (65.19 %) and buffer properties in acid and basic medium. The mentioned characteristics are important to incorporate the microorganisms and to keep them viable during storage and proliferation on soil. Six different genres of microorganisms (bacteria and fungus) were used as study models, isolated from petroleum hydrocarboncontaminated soils from Southern Mexico. CFU/mL values 10 to 1000 times above those observed in control samples were obtained in culture tests in liquid with BIODAC. The inhibition of microbial growth was not observed in the assays on petri dishes with agars containing granules that occupied 10, 50 and 100 % of the surface. It is possible to recover live microorganisms after 42 days of storage on desiccating state in BIODAC. The number of living microorganisms was maintained on a considerable level, above 10 9 (CFU/g). The experiments to define the effects of BIODAC 12/20 on plant growth were carried out using the granule quantity (equivalent to 1 % of soil volume) that saturated the surface of the container It was demonstrated that the product did not inhibit the emergence time and biomass production. It was observe that after 40 days in the open air, previously inoculated model microporganisms on artifically soil (6 % hydrocarbons), the CFU with BIODAC was up to 100 % times greater than without BIODAC. |
