A new species, Mygdonia milivoji sp. nov. (Coreidae: Coreinae: Mictini) from south-west Madagascar is described, illustrated and compared with widely distributed M. elongata Distant, 1879. A key to Mygdonia species based on females is given and distribution of both Madagascan species is briefly discussed.

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

Secondary metabolites of the marine sponges Acanthella elongata, Axinella donnani, Callyspongia diffusa, Callyspongia subarmigera, and Echinodictyum gorgonoides were collected from fishing nets and their in vitro antibacterial properties against eight virulent marine fish pathogens were studied at incubation temperatures of 20°C and 30°C. Crude methanol extracts of the tested sponges showed spe...

New species of ciliates belong to genus Metaradiophrya was recorded from intestine of Pheretima elongata, collected from Aurangabad district (M.S.). In the present study, morphological characteristics of this ciliate and its similarities and differences were discussed compared with other species of this genus.

After preliminary screening, Mortierella alpina and Mortierella elongata were compared with respect to arachidonic acid content. M. alpina ATCC 16266 produced 2.1 g of arachidonic acid per liter in media containing 10% glucose while the highest percentage of arachidonic acid in lipid (43.3%) was observed at a glucose concentration of 2%. Arachidonic acid content in lipids increased to 66% durin...

A new family, the Hafomonadaceae, has recently been proposed for members of the genera Deleya and Halornonas. The three strains investigated, Deleya haiuphila, Halomonas elongata and Flavobacterium halmephilum (reclassified as H. hahophila), are aerobic heterotrophic micro-organisms exhibiting an extreme salt tolerance. The major organic osmoregulatory solutes of these organisms were examined u...

The genus Spasskia Belokobylskij, 1989 (Hymenoptera: Braconidae: Helconinae) is reported for the first time from China. Two species, namely Spasskia brevicarinata Yan et Chen sp. n.and Spasskia indica Singh, Belokobylskij et Chauhan, 2005 are described and illustrated. A key to the species of this genus is updated to include the new species.

The 'acaecate' Pheretima group from Vietnam is revised, with description of a new species, Polypheretima mekongmontis sp. nov. A total of 18 species of three genera, Metapheretima Michaelsen, 1928, Planapheretima Michaelsen, 1934, and Polypheretima Michaelsen, 1934 has been recorded from Vietnam. Caecate species of Planapheretima are included here as well. Planapheretima arboricola (Rosa, 1890)...

Choline dehydrogenase (EC 1.1.99.1) catalyzes the four-electron oxidation of choline to glycine-betaine via a betaine-aldehyde intermediate. Such a reaction is of considerable interest for biotechnological applications in that transgenic plants engineered with bacterial glycine-betaine-synthesizing enzymes have been shown to have enhanced tolerance towards various environmental stresses, such a...
