Ultrastructural features of the gastric caeca of Odontosciara sp. are reported. The species has 4 lateral caeca connected with the anterior midgut at the level of the foregut junction. The epithelial cell features indicate protein synthesis, digested material absorption from the lumen and haemolymph material absorption. Those functions, however, do not seem to be very intense.

Two ascomycetous yeast species, Candida flosculorum sp. nov. and Candida floris sp. nov., were isolated from tropical flowers and their associated insects. C. flosculorum was isolated from flower bracts of Heliconia velloziana and Heliconia episcopalis (Heliconiaceae) collected from two Atlantic rain forest sites in Brazil. C. floris was isolated from flowers of lpomoea sp. (Convolvulaceae) growing on the banks of the river Paraguai in the pantanal ecosystem in Brazil and from an adult of the stingless bee Trigona sp. and a flower of Merremia quinquefolia (Convolvulaceae) in Costa Rica. C. flosculorum belongs to the Metschnikowiaceae clade and C. floris belongs to the Starmerella clade. The type strain of C. flosculorum is UFMG-JL13(T) (=CBS 10566(T) =NRRL Y-48258(T)) and the type strain of C. floris is UWO(PS) 00-226.2(T) (=CBS 10593(T) =NRRL Y-48255(T)).

Strains belonging to two novel yeast species, Candida bromeliacearum and Candida ubatubensis, were isolated from the bromeliad tank of Canistropsis seidelii (Bromeliaceae) in a sandy coastal plain (restinga) ecosystem site in an Atlantic rainforest of south-eastern Brazil. These species were genetically distinct from all other currently accepted ascomycetous yeasts, based on sequence divergence in the D1/D2 domains of the large-subunit rDNA and in the small-subunit rDNA. The species occupy basal positions in the Metschnikowiaceae clacle. The type strains are Candida bromeliacearum UNESP 00-103(T) (=CBS 10002(T) = NRRL Y-27811(T)) and Candida ubatubensis UNESP 01-247R(T) (=CBS 10003(T) = NRRL Y-27812(T)).

beta-Glucosidase and beta-xylosidase production by a yeastlike Aureobasidium sp. was carried out during solid-state and submerged fermentation using different carbon sources and crude enzymes were characterized. beta-Glucosidase and beta-xylosidase exhibited optimum activities at pH 2.0-2.5 and 3.0, respectively. These enzymes had the maximum activities at 65degreesC and were stable in a wide pH range and at high temperatures.
