Biodegradable poly (hydroxyalkanoates) are truly biodegradable plastics with unique biocompatible properties. Three different biodegradable polymers namely poly (hydroxybutyrate), poly(hydroxybutyrate-co-valerate) and poly (hydroyalkanoates) with 6,8,10,12 & 14 C alkyl chains have been produced through microbial fermentation processes using palm oil as a substrate. Two potential uses of these polymers are biodegradable packing and in pharmaceutical emulsion system.
