Description The aim of this work was to study the biodegradation of food waste employing thermostable a-amylase
and cellulase enzymes producing bacteria. Four potential isolates were identified which were capable of
producing maximum amylase and cellulase and belong to the amylolytic strains, Brevibacillus borstelensis
and Bacillus licheniformis; cellulolytic strains, Bacillus thuringiensis and Bacillus licheniformis, respectively.
These strains were selected based on its higher cell density, enzymatic activities and stability at a wide
range of pH and temperature compared to other strains. The results indicated that 1:1 ratio of pre and
post consumed food wastes (FWs) were helpful to facilitate the degradation employing bacterial consortium.
In addition, organic matter decomposition and chemical parameters of the end product quality also
indicated that bacterial consortium was very effective for 1:1 ratio of FWs degradation as compared to
the other treatments.
