CHEMICAL CHANGES IN THE GROWTH MEDIUM OF MICROCYSTIS, BATCH CULTURES GROWN AT STRESS AND NON-STRESS LIGHT INTENSITIES
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: G H J Krüger --- Botany Department, South Africa JN Eloff --- Botany Department, South AfricaThe modified BG 11 growth medium used in this study has a poor buffer ability and large pH changes occurred during growth of Microcystis. Inhibition of growth in cultures grown at stress light intensity (26 μEinst m−2 sec−1) could be... -
