Future research will focus on advancing microbial biotechnology through the following key directions:

• Microbial Culture Identification & Strain Improvement
• Enhance strain improvement strategies to optimize yield and stability of industrially important microbes.
• Bioprocessing & Enzyme Applications
• Scale up bioprocesses for the production of industrially relevant enzymes.
• Microbial Consortia Discovery
• Investigate microbial consortia of agricultural and industrial importance.
• Develop diagnostic tools for identifying disease-causing microbial consortia in medical and agricultural systems.
• Microbial Biobank Development
• Establish a Microbial Biobank of indigenous industrially important strains.
• Provide a sustainable resource for ongoing and future research, enabling students and scientists to access diverse microbial collections for industrial, food and agriculture benefits.
