Thermo gravimetric analysis of the HIPS film was done to check
the weight loss of the film after and before treatment with the bacterial
isolates. TA, USA model TGA Q50 was used for analysis. Temperature
range was adjusted between 50 and 700 C. Film was
heated in a platinum pan and nitrogen was flushed into the pan
at a rate of 50 ml min1, this was done in order to reduce the corrosion
due to release of HBr, from flame retardant HIPS
