Research Progress in Carbon Sequestration by High-valued Isochrysis Strain
摘要
Abstract
CO2 is one of the main greenhouse gases.A large amount of CO2 is released into the atmosphere through industrial production and human activities,leading to a significant increase in global CO2 concentration.This has resulted in the increasing global temperatures,climate warming,and frequent occurrences of extreme weather events,posing a threat to global human security.In order to mitigate the increase of CO2 and address global warming,countries around the world have set carbon peak targets and are committed to carbon capture and utilization.Marine Isochrysis galbana characterizes of a fast growth rate and high carbon-fixing efficiency;moreover,biological carbon sequestration mediated with Isochrysis strain and wastewater synthesized various high-value biologically active substances such as protein,polyunsaturated fatty acids;which is regarded to be a promising way of fixing CO2.In this review,we firstly summarize the prevalent CO2 capture technologies and compares their advantages and disadvantages.Furthermore,we elaborate the carbon metabolism mechanism of Isochrysis strain for the carbon fixing process,and explain the relationship among the Calvin cycle,TCA cycle,and the metabolism of various biologically active substances during photosynthetic carbon fixation.Based on the photosynthetic carbon-fixing mechanism of Isochrysis strain,we propose some methods about cultivation conditions,photobioreactors and modified microalgal cells by genetic engineering and synthetic biology to improve carbon-fixing efficiency for Isochrysis strain.Lastly,we illustrate the correlation between carbon fixation of Isochrysis strain and the synthesis of bioactive components,offering essential details for high valued Isochrysis-derived bioproducts by deep processes.This review will provide essential perspectives to address carbon neutrality by microalgal carbon sequestration and exploit high-value microalgal bioproducts by Isochrysis strain.关键词
