Abstract
The management of the generated waste is a major problem in developing countries. The waste generated in the agroprocessing has been used as sources of nutrients for the microbes. In the present study, a medium has been formulated with banana fruit stalk and the microbial growth was monitored. Growth and biomass production was examined on banana stalk agar (BSA) and broth (BSB), banana stalk dextrose agar (BSDA) and broth (BSDB) using commercial potato dextrose agar (PDA) and broth (PDB) as control. It was observed that the good microbial growth was observed when compared to that of other conventional growth media. The weight of the Aspergillus niger biomass in BSDB was 1.8 g after 4 weeks of growth and the weight of the biomass in PDB was 0.9 g. The remarkable growth on BSDB may be attributed that the banana stalk is highly rich in nutrients.
