Title: Studies on a phycocolloid from red alga Halymenia venusta Boergesen Authors: Parekh, R G; Doshi, Y A; Rao, A V; Chauhan, V D Abstract: A phycocolloid extracted from H. venusta, collected from the west coast of India, was characterized as lambda carrageenan having 43% yield on dry weight basis. The extract showed positive optical rotation and was soluble in 3 MKCl, cold and hot water and hot milk. The extract tested positive with methylene blue and the infrared spectrum was very similar to the known spectrum of lambda carrageenan. Page(s): 274-276

Title: Lipid content of some Indian seaweeds Authors: Parekh, R G; Chauhan, V D Abstract: Total lipid content was estimated in 21 genera comprising 31 species of green, brown and red seaweeds of Tamil Nadu and Gujarat coasts. It varied from 19 to 85, 17 to 65 and 20 to 71 mg.g^-1 respectively in green brown and red seaweeds on dry weight basis. Codium dwarkense, Padina gymnospora and Laurencia cruciata showed high total lipid content (respectively 85, 65 and 71 mg.g^-1). Page(s): 272-273

Title: Biochemical Composition of Some Benthic Marine Algae of the Vestfold Hills, Antarctica Authors: Dhargalkar, V K; Reddy, C R K; Deshmukhe, G V; Untawale, A G Abstract: Nine algal species were analysed for their biochemical constituents like carbon, nitrogen, carbohydrate, protein, lipids and calorific values. Porphyra endiviifolium comparatively had the highest level of carbon (34.20%), nitrogen (4.67%), protein (27.95%) and lipids (3.85%). C:N values showed direct relationship with carbohydrate and protein and inverse relationship with lipids. Page(s): 269-271

Significance of tissue aminotransferases in brachyuran species of diverse habitats

Title: Significance of tissue aminotransferases in brachyuran species of diverse habitats Authors: Rao, K V Ramana; Dayakar, Y Abstract: In the tissues of Scylla serrata (Forskal) from brackish water, Ocypode platytarsis (Milne H. Edwards) from seacoast and Oziotelphusa senex senex (Fabricius) from paddy fields the free amino acid (FAA) content is high. The muscle has the highest FAA content. The tissue aspartate (AAT) and alanine (AlAT) aminotransferase activities are high in muscle followed by gill and midgut gland indicating operation of gluconeogenesis for energy. AAT/AlAT ratios in the tissues largely demonstrate preponderance towards anaerobic metabolism. The AlAT activity also indicates adaptability of these brachyurans to their respective habitats against temperature, salinity, oxygen content, etc. Page(s): 267-268
