The Elfvingia applanata (EA), Hericium erinaceum (HE),Grifola frondosa (GF), Pholiota nameko (PN), Pleurotus eryngii (PE), Trametes suaveolens (TS), Fomes fomentarius (FF), and Inonotus obliquus (IO) could produce the endo- (EN) and exo-biopolymer (EX) in submerged culture. The highest anti-complementary activity of the EN was exhibited by PN (49.1%), followed by HE (38.6%), TS (37.0%),and FF (...

Twelve new species and two new genera are described from Bahia (Brazil): Ectenessa aurantiaca (Ectenessini); Stizocera lingafelteri (Elaphidiini); Raglicia monnei (Graciliini), new genus and species; Tobipuranga aspera (Heteropsini); Cicatrion unicolor, and Pygmodeon obscurum (Neoibidionini); Neophygopoda agdae (Rhinotragini); Arapari bellus (Trachyderini), new genus and species; Meridiotroctes...

Growth intensity o f the green alga, Scenedesmus obliquus, was measured in autotrophic cultures, diluted once daily, between 20 and 30 °C in a light-dark cycle o f 16 : 8 h at initial optical densities between 0.02 and 1.2. Arrhenius analyses o f the results showed linear relationships be­ tween growth intensity and temperature below the temperature optimum. The temperature effects on growth, a...

The nucleotide sequence of the cytoplasmic 5S ribosomal RNA from Scenedesmusobliquus has been determined using post-labelling techniques. The sequence is closely related to the 5S RNA sequence of Chlorella and contains all the areas of invariant sequence which appear to be conserved in plant cytoplasmic 5S RNA species.
