 Title    Sterols and Polysaccharides in Freshwater Algae Spirogyra and Mougeotia  
 Abstract    Several species of freshwater green algae belonging to the order Zygnematales (Spirogyra crassa (Ktz.) Czurda, S. condensata (Vauch.) Czurda, S. longata (Vauch.) Ktz., S. juergensii Ktz., S. olivascens Rabenh. and M ougeotia viridis (Ktz.) Wittr.) were shown to have specific sterol content and characteristic monosaccharide composition o f the biomass. Polysaccharide fractions were obtained by stepwise extraction of S. condensata and characterised by a deter­ mination of monosaccharides liberated after acid hydrolysis. A ction of amyloglucosidase was used to prove the presence o f starch in algal biomass. The main polysaccharide seems to be a complex mucilage com posed of rhamnose, arabinose, xylose, galactose, and uronic acid, and the structure of this mucilage needs further investigation.

 Title    Volatile Components of the Freshwater Algae Spirogyra and Mougeotia  
 Abstract    Several species of freshwater green algae belonging to the order Zygnematales (Spirogyra crassa (K tz.) Czurda, S. longata (Vauch.) Ktz., and Mougeotia viridis (K tz.) W ittr.) were found to have a specific composition of the volatile fraction, which confirms an earlier pro­ posal for the existence of two groups in the genus Spirogyra. Antibacterial activity was found in volatiles from S. longata.
