The immense use of conventional plastic is becoming the major cause of environmental issues. To solve these problems, bioplastic is a promising alternative of conventional plastic. The polyhydroxybutyrate (PHB) is a common biodegradable bioplastic naturally synthesized in various microorganisms. The main limitation with bacterial fermentation-based PHB bioplastic is its high production cost. This study aimed to screen, optimize, and selection of cyanobacteria, the oxygenic photosynthetic prokaryotes, for PHB production. Ten cyanobacterial morphotypes isolated from Garhwal Himalaya. The highest PHB content 1.38% was noted in Leptolyngbya sp. and lowest 0.24% in Cylinderospermum sp. Similarly, in case of biomass yield, highest 6.16 (g/L) biomass observed in Leptolyngbya sp. and lowest 0.986 (g/L) biomass noted in Cylinderospermum sp. Based on the current findings, Leptolyngbya sp. might be the promising candidate for PHB production. [ABSTRACT FROM AUTHOR] |
