Item On the ultrastructure of the cell wall and pit plugs of Chondrococcus hornemannii (Rhodophyta, Cryptonemiales)(Botanica Marina, 1977) Mshigeni, Keto E.The Ultrastructure of the cell wall of Chondrococcus hornemannii is being reported for the first time. Amongst the notable features revealed in this study are: the stratified appearance of the wall, the presence of distinct lenticular pit plugs where the wall is interrupted by pit connections, and the presence of floridean starch grains scattered in the cytoplasm.Item Studies on the yield and infrared spectra of Phycocolloids from Chondrococcus hornemannii (Lyngbye) Schmitz and Sarconema filiforme (Sonder) Kylin from Tanzania(De Gruyter, 1977) Mshigeni, Keto E.Phycocolloids from Chondrococcus hornemannü and Sarconema filiforme have been investigated and found to be cairageenans. Yields of 45.1 ±0.1 and 35.7 ± 2.8% (of the dry weight) were obtained in the two species, respectively. The phycocolloid from S. filiforme showed a total sulphate of 18.3 ± 0.5% and IR absorption peaks characteristic of i-carrageenan. That of C hornemannü showed a sulphate content of 24.7 ± 0.3% and IR spectra and solubility properties akin to those of y-carrageenan. The economic potential of the seaweeds is discussed.
