Abstract

Coffee residues are generated in large quantities from the processing and consumption of coffee, and are generally disposed of as waste through non-sustainable practices. The capacity of coffee residues to support microbial growth was determined, using indigenous bacteria and fungal species- Aspergillus awamori and Aspergillus oryzae as model organisms. Solid and liquid state fermentation by fungal species and indigenous bacteria respectively, were carried out under basic conditions and the results showed that coffee residues contain chemical compounds which can be utilized by micro-organisms in bio-processes to produce value-added products. Increase in free amino nitrogen and total reducing sugars was obtained; and maximum protease activity of 92 U/g dry matter basis was obtained.
