title: Cell volume distribution dynamics of Chlorella vulgaris Beij. in batch cultures under continuous light.
abstract: Cell volume distribution in Chlorella vulgaris cultures coming out of senescence was measured by flow cytometry every 6 h for 114 h in a full-factorial experiment with initial nitrate (420-4200 microg NO3-N l(-1)), phosphate (9-186 microg PO4-P l(-1)), and continuous light (50-330 microE m(-2) s(-1)) as treatments. The maxima in median and median absolute deviation (MAD) of cell volume were achieved within 6 h of each other and their timing was not affected by any treatment. Population specific growth rate during the first 66 h calculated from volume distribution changes was significantly affected by light treatment only (p=0.002).
