Babassu coconut mesocarp (Orbignya sp.) as carbon source for production of culture media for Trichoderma

Abstract

Biological control has been studied as an alternative replacement of chemicals in agriculture . One of the microorganisms used in this system is the fungal species Trichoderma sp. In this work, media formulations were tested by replacing glucose babassu mesocarp (Orbignia sp.) Which has 69.46% starch in the composition. These culture media were used to cultivate three strains of the fungus Trichoderma . It was observed that the composition of the medium did not affect the growth of which statistically tested concentrations did not differ . For the time of 72h was no significant difference (p < 0.05) in diameter growth of strain 63 for the other however to the total time of the experiment the standard species proved stronger for longer, staying in log phase to the time 96 hours. The concentrations of immediate substituted carbon source (dextrose) at babassu mesocarp did not affect the growth of the fungus suggests that the mesocarp babassu is a good carbon source for the production of growth medium.
