โœฆ Synopsis

Synchronous cultures of Chlamydomonas reinhardii have been examined for the total amounts of carotenoid and chlorophyll present throughout a 12 hrs light-4hrs dark life cycle. Variations in the carotenoid distribution at different points within the cell cycle have been found. During the greater part of the light period all major carotenoids increased at a proportionally similar rate. However, the increases in lutein and violaxanthin preceded those in /?-carotene and neoxanthin by some 2 hrs and that in loroxanthin, an algal xanthophyll, by about 3 hrs. A marked drop in total carotenoid

The carotenoid content of Mytilus edulis was studied over a period of 3 years from t965 to 1967; a seasonal cycle was observed which appeared to be controlled by the spring bloom of phytoplankton, and the sexual cycle of the mussel.

## Abstract KB cells were grown in suspension culture and synchronized with a double thymidine block. Cells were removed at various times during the cell cycle and analyzed for sialic acid, fucose, mannose and galactose. The mannose, galactose, and fucose contents of the cells all showed a decrease
