Commercial media from the Hyponex series were shown to contribute different benefits to terrestrial plants with their differing N:P:K ratios. This study investigated the effects of different media N:P:K ratio, media concentrations, and re-supplementation frequencies on the growth of Isochrysis galbana, Nannochloropsis oculata, and Tetraselmis chui. Of the five types of media, H5 (N:P:K=3:1:1) performed the best when each medium was added at 10 mg l-1. H5 medium provided at 50 mg l-1, 100 mg l-1, and 100 mg l-1 allowed for the optimal growth of I. galbana, N. oculata, and T. chui, respectively. When there were re-supplementations of 50 mg l-1 H5 medium during a 14-day cultivation period, re-supplementation only on day 8 was optimal for I. galbana, while re-supplementati.. View More»
