Isolation and physiological characterization of two novel, piezophilic, thermophilic chemolithoautotrophs from a deep-sea hydrothermal vent chimney
Provedor de dados: 5

P&gt;Two novel, thermophilic piezophiles, capable of chemolithoautotrophic growth, are successfully cultivated and isolated from a black smoker chimney at the TAG field (Mid Atlantic Ridge: MAR) by using a piezophilic cultivation technique. Both strains (strains 106 and 108) represent dominant cultivated populations of the microbial communities in the chimney surface habitat. Strain 106 represents typically thin, long spiral cells under the piezophilic growth condition but short bent cells under the non-piezophilic condition. It is a strictly chemolithoautotrophic gammaproteobacterium using reduced sulfur compounds as the electron donors, and nitrate and O-2 as the electron acceptors. Based on the 16S rRNA gene sequence, strain 106 would represent a novel...

A new troglobitic genus and species, viz. Speleodentorcula beroni gen. &amp; spec. nov., is described from the island of Euboea, Greece. The species, known from a single cave only, is quite isolated systematically. According to the structure of its shell and the genitalia S. beroni should be classified with the Orculidae. Within this family Speleodentorcula is most similar to Walklea anatomically; conchologically there is some vague resemblance to Fauxulus (apertural denticles) and Odontocyclas, Walklea, Fauxulus and Afriboysidia (surface sculpture). Speleodentorcula alone is considered the sister group of the taxon encompassing these last mentioned four genera.

New cave-dwelling amphipods (Lysianassidae, Hadziidae) from the Dominican Republic (Hispaniola)
Provedor de dados: 16
Autores: Jaume, Damià; Wagner, H.P.
Two new stygobiont amphipods are described from anchialine caves located in the Jaragua region (Pedernales Prov., Dominican Republic, Hispaniola). Ottenwalderia kymbalion gen. et sp. nov. is the first lysianassoid known to have penetrated into completely fresh waters, and the fourth colonizing hypogean habitats. Bahadzia jaraguensis sp. nov. is the second representative of this West Indian thalasso-stygobiont genus to be reported from fresh waters; it exhibits the most troglomorphic aspect (i.e. elongation of first antennae and sixth pereiopods) recorded for the genus. Its diagnosis is complemented with a key to the species of the genus Bahadzia. The in situ swimming behaviour of both taxa is briefly described. It is postulated that both amphipods share a...
