||The combined stress of nutrient limitation and suboptimal temperature on growth was studied with turbidostat and chemostat cultures of Scenedesmus sp. and Asterionella formosa. The combined effects were greater than the sum of individual effects and were not multiplicative. In N- and P-limited Scenedesmus sp. and A. formosa the cell quotas of both limiting and nonlimiting nutrients increased with decreasing temperature. At a given temperature cell quotas of limiting nutrients also increased with the growth rate and followed a saturation function. Higher values of the minimum cell quota (q sub o) at lower temperatures show that cells require more nutrient with decreasing temperature. The optimal growth temperature range, however, was 20-25C.
