Spirhapalum siamensis n. sp. obtained from the heart of the Malayan box turtle, Cuora amboinensis, from western Thailand is described. This blood fluke differs from the 2 previously known species of Spirhapalum in its larger overall body size, constricted mid-body, greater number of pre-ovarian testes, ceca that loop anteriorly from the cecal bifurcation before turning to the posterior, and the...

Bioactive-directed fractionation of n-butanol extract from fresh fruits of Randia siamensis led to isolate of 4 new pseudoginsenoside compounds: pseudoginsenosides-RT2, -RT3, RT4 and -RT5, together with 7 known compounds: tyramine, pseudoginsenosides-RT1 methyl ester, pseudoginsenosides-RT1, pseudoginsenoside-RP1, kaempferol-3-O-β-D-xylose(1-2)-βgalactose, kaempferol-3-O-β-D-galactose, and 5-O...

A new species of Baetidae, Alainites siamensis sp. nov. , is described from Thailand. This closely related to lingulatus Tong & Dudgeon, 2000, laetificus (Kang Yang, 1994) and yixiani (Gui Lu, 1999). Species delimitation based on morphological molecular (mitochondrial COI sequences) evidence provided. The discovery this confirms the wide distribution Waltz McCafferty, 1994 in Southeast Asia.

Cellulase is a family of at least three groups of enzymes that participate in the sequential hydrolysis of cellulose. Recombinant expression of cellulases might allow reducing their production times and increasing the low proteins concentrations obtained with filamentous fungi. In this study, we describe the production of Trichoderma reesei cellobiohydrolase II (CBHII) in a native strain of Wic...

Two new species, Gnaphosa koponeni sp. n. (♂♀, Tuva, Russia) and G. tunevae sp. n. (♀, Mongolia) are described. New figures and distribution data are provided for G. gracilior Kulczyński, 1901, G. kansuensis Schenkel, 1963, G. mandschurica Schenkel, 1963, G. sticta Kulczyński, 1908, G. stoliczkai O. Pickard-Cambridge, 1885 and G. wiehlei Schenkel, 1963. Additional morphological evidence is prov...
