Growth improvement and metabolic profiling of native and commercial Chlorella sorokiniana strains acclimatized in recycled agricultural wastewater

摘要

Highlights?Native strain was more tolerance towards low light compared to commercial strains.?Substantial deviation of metabolic profile among morphologically identical strains.?Three cycles of acclimation has remarkably improved microalgae growth.?Recycling of final effluent is feasible method to dilute the wastewater.?Acclimation and dilution using final effluent has eliminated microalgae lag phase.AbstractThis study investigated acclimation ability of nativeChlorella sorokiniana(CS-N) and commercialChlorella sorokiniana(CS-C) in palm oil mill effluent (POME), their metabolic profile and feasibility of effluent recycling for dilution purpose. Maximum specific growth rate, μmaxand lag time, λ of the microalgae were evaluated. Result shows
