Abstract

Whey is the liquid portion of milk that remains after the curd (milk casein) is separated from the solid portion that results from milk coagulation. Microalgae are known to efficiently remove a range of contaminants from wastewater, combining the high-value biomass production system for commercialization with agroindustry waste treatment is one practical way to lower the costs of microalgae cultivation. This study aims to cultivate Scenedesmus quadricauda on standard media supplemented with cheese whey, then the pellet after growth was taken and resuspended in the soaking water to investigate its effect on the growth and development of Lactuca sativa. The algal treatments enhanced Lactuca sativa growth parameters, as well as an increase in carbohydrate content compared to the control plant during the vegetative stage.
