Conclusions
PBs has found applications in agriculture, fishery, forestry and civil engineering as packaging materials, vegetation nets, mulching compost bags [28] In film and this work, we reported the isolation of a thermophilic actinomycete, Actinomadura sp. strain TF1 capable of degrading various aliphatic polyesters. Strain TF1 could produce PBs depolymerase enzyme in PBs film and emulsified PBS in basal medium. Production of the highest PBS depolymerase activity was optimized at 45°C pH 7.0 and used PBS and yeast extract plus ammonium sulphate as carbon and nitrogen source, respectively. Thus, this strain has potential for application in biodegradable plastic composting technology. This study is the first report for the optimization of PBS erase production by Actinomadura sp. strain TF1. However, further studies were in progress in the purification of PBS depolymerase and determined depolymerase gene in strain TF1.
