Evaluation of Microalgae’s Plastic Biodeterioration Property by a Consortium of Chlorella sp. and Cyanobacteria sp.

Malaysia is one of the top eight countries that has a drawback mismanaged plastic waste. This study intended to investigate polymer degradation using biological technique with help microalgae minimise time required for biodegradation. research article aims identify collected sample most suitable biodegradation microplastic and analyse by microalgae. The results revealed consortium Chlorella sp. Cyanobacteria were able deteriorate low-density polyethene (LDPE sample) through several stages, this was confirmed UV-Spec, FESEM, EDX, CHNO, FTIR DSC analysis. obtained producing exopolysaccharides (EPS) decreased carbon oxygen ratio. According SEM micrographs, microalga may colonise, agglomerate, adhere microplastics its surface, regardless fractional size. EDX analysis showed initial composition 92.30 ± 1.23 %, while after incubation, started decreasing from 53.18 % 39.12 1.08 %. Finally, there 37.91 decrease in weight elemental analysise
