Two distinct mitochondrial genome types have been described among the green algal lineages investigated to date: a reduced-derived, Chlamydomonas-like type and an ancestral, Prototheca-like type. To determine if this unexpected dichotomy is real or is due to insufficient or biased sampling and to define trends in the evolution of the green algal mitochondrial genome, we sequenced and analyzed t...

Eleven years of water quality time-series of the two Dutch lakes Veluwemeer and Wolderwijd were subject to predictive modelling by recurrent supervised artificial neural networks (RNN) and hybrid evolutionary algorithms (HEA). The modeling aimed at forecasting changes of the phytoplankton community in response to the control of external nutrient loadings and fish abundances as consecutively imp...

Apparent size of the photosynthetic unit (chlorophyll/O(2) per flash) was estimated by O(2) yield of repetitive short flashes on cell samples taken at various times from a synchronized culture (14-hour light, 10-hour dark) of Scenedesmus obliquus. Unit size was essentially invariant (< 10% variation) with a mean value of 1750 chlorophyll/O(2) per flash. In contrast, the light-saturated photosyn...

The production of d-lactic acid, a major fermentation product of Scenedesmus obliquus strain D(3), is inhibited by light. This inhibition has been observed in the wild type as well as in Bishop's mutant 11. However, in mutant 8, which lacks photophosphorylation, light stimulated the formation of d-lactic acid.
