Isolation and characterisation of fibrolytic and lipolytic enzyme-producing bacteria from oil palm empty fruit bunch compost

Palm kernel pulp (PKC) is one of the important waste products of palm oil. PKC has been used as feed for ruminant animals and poultry and ducks. The use of PKC in general poultry and duck feed is limited due to the anti-nutritional properties such as galactomannan and xylan found in PKC. These anti-...
