 Title    Changes of C-Phycocyanin in Synechococcus 6301 in Relation to Growth on various Sulfur Compounds Materials and Methods  
 Abstract    The cyanobacterium Synechococcus 6301 is able to use a lim ited number o f sulfur com pounds as the only source o f sulfur supply such as sulfate, thiosulfate, thioacetic acid, m ercaptoacetic acid, thioacetam ide, L-cysteine and glutathione. Com pounds containg thioether linkages such as methionin or S-m ethylcysteine and all com pounds investigated so far containing sulfonic acid structures do not support growth. Growth inhibiton was observed by addition o f am inom ethane-sulfonic acid or cysteamine. When non-growth sustaining sulfur com pounds are added as sulfur source, the C-phycocyanin content o f the Synechococcus cultures decreased drastically, causing a shift in color from blue-green to yellow-green. An analysis reveals the degradation o f C -phycocyanin whereas chlorophyll formation still proceeds to a certain degree in growing sulfur-starved cells. Supplem entation o f a suitable sulfur source induces a period o f intense and preferential C-phycocyanin synthesis prior to resumption o f normal growth.
