This study aimed to investigate the morphology of fungi, Trichoderma reesei RT-P1, and yeast, Saccharomyces cerevisiae RT-P2, culturing in Potato Dextrose Agar (PDA) for the use of co-cultures in the production of ethanol. It was found that mycelium of Trichoderma reesei RT-P1 were grown on top of Saccharomyces cerevisiae RT-P2. The co-cultures were grown on PDA better than pure cultures. Morphological studies of the co-cultures by transmission electron microscope and scanning electron microscope showed that the sizes of conidiophore, phaialide and spore were larger. The present study suggest that the morphology of the co-cultures is a useful technique to indicate the conversion of cellulose to ethanol production.
