摘要

Abstract > Present study aims to optimize the production of starch and total carbohydrates from Arthrospira platensis . Growing concerns toward unprecedented environmental issues associated with plastic pollution has created a tremendous impetus to develop new biomaterials for the production of bioplastic. Starch‐based biopolymers from algae serve as sustainable feedstock for thermoplastic starch production due to their abundant availability and low cost. A. platensis was cultivated in Zarrouk's medium at 32?±?1°C and exposed to red light with a photoperiod of 12:12?hr light/dark. Growth kinetics studies showed that the maximum specific growth rate ( μ <sub>max</sub> ) obtained was 0.059?day ?1 with the doubling time ( t <sub>d</sub> ) of 11.748?days. Subsequently, Zarrouk's medium with different concentrations of sulfur, phosphorus and nitrogen was prepared to establish the nutrient‐limiting conditions to enhance the accumulation of starch and total carbohydrates. In this study, the highest starch accumulated was 6.406?±?0.622?mg?L ?1 under optimized phosphorus limitation (0.025?g?L ?1 ) conditions. Nitrogen limitation (0.250?g?L ?1 ) results demonstrated significant influenced ( p ??0.05) on total carbohydrates (67.573?±?2.893?mg?L ?1 ) accumulation in <fc> <fi>A. platensis</fi> </fc> . The starch accumulation in <fc> <fi>A. platensis</fi> </fc> was significantly affected ( p ??0.05) by phosphorus limitation (0.0025?g?L ?1 ). Subsequently, the optimized phosphorus concentration was coupled with mixotrophic cultivation to further enhance the starch accumulation. The results obtained indicated that, the starch (11.426?±?0.314?mg?L ?1 ) and carbohydrates (43.053?±?2.986?mg?L ?1 ) concentration obtained was significantly high ( p ??0.05) under mixotrophic cultivation. Therefore, it shown that nutrient limitation and mixotrophic cultivation are viable strategies to enhance the accumulation of starch and total carbohydrates in <fc> <fi>A. platensis</fi> </fc> .
