Several bacteria have been observed as tolerant to the plastic waste according to previous studies. However, its ability as in biodegradation of plastic and biological fertilizers has not been previously tested. Therefore this research is intended to test the potential ability of these bacteria as in biodegradation of plastic waste and biological fertilizer by using Gas Chromatography-Mass Spectrophotometry (GC-MS) technique. According to GC-MS analysis results on SP6 isolates as plastic-tolerant bacterial models, have obtained 5 specific secondary metabolites which act as biodegradation of plastic with the composition as follows: Malic acid ( 4 6 5 ) 1.85%, Xanthine ( 5 4 4 2 ) 1.08%, Myo inositol ( 6 12 6 ) 1.32%, γ Glutamyl alanine ( 8 14 2 5 ) 0.85% and Ribitol 5 phosphate ( 5 13 8 ) 1.30%. In addition, the isolate was also able to synthesize several phytohormonesan indicator for potential use as biofertilizer-with the composition as follows: α Aminobutyric acid3 (C 4 H 9 NO 2 ) 1.20%, Indoleacetic acid (C 10 H 9 NO 2 ) 1.85%, Kinetin (C 10 H 9 N 5 O) 1.19%, Kinetin glucoside (C 16 H 19 N 5 O 7 ) 1,19 % and Benzyladenine 9 glucoside N6 (C 18 H 21 N 5 O 5 ) 1.31%. It is therefore, the bacterium has a double potentiality not only to degrade plastics, but also to be used as a bio-fertilizer.
