Roseimaritima ulvae gen. nov., sp. nov. and Rubripirellula obstinata gen. nov.,...
Bondoso, Joana; Albuquerque, Luciana; Nobre, M. Fernanda; Lobo-da-Cunha, Alexandre; Costa, Milton S. da; Lage, Olga MariaFour isolates, belonging to the deep-branching phylum Planctomycetes, were recovered from the biofilm of two marine macroalgae, Ulva sp. and Laminaria sp., from the Northern coast of Portugal. These strains were light pink- or red-pigmented; the cells were variable in shape and usually organized in rosettes. They had a dimorphic cell cycle with budding reproduction. The organisms were chemoheterotrophic, strict...
Bacillus isabeliae sp. nov., a halophilic bacterium isolated from a sea salt ev...
Albuquerque, Luciana; Tiago, Igor; Taborda, Marco; Nobre, M. Fernanda; Veríssimo, António; Costa, Milton S. daA low-G+C, Gram-positive isolate, designated strain CVS-8(T), was isolated from a sea salt evaporation pond on the Island of Sal in the Cape Verde Archipelago. This organism was found to be a catalase- and oxidase-positive, non-motile, spore-forming, aerobic, curved rod-shaped organism with an optimum growth temperature of about 35-37 degrees C and an optimum pH between 7.5 and 8.0. Optimal growth occurred in m...
A new lineage of halophilic, wall-less, contractile bacteria from a brine-fille...
Antunes, André; Rainey, Fred A.; Wanner, Gerhard; Taborda, Marco; Pätzold, Jürgen; Nobre, M. Fernanda; Costa, Milton S. da; Huber, RobertA novel strictly anaerobic bacterium designated strain SSD-17B(T) was isolated from the hypersaline brine-sediment interface of the Shaban Deep, Red Sea. Cells were pleomorphic but usually consisted of a central coccoid body with one or two "tentacle-like" protrusions. These protrusions actively alternated between a straight, relaxed form and a contracted, corkscrew-like one. A peptidoglycan layer was not detec...
Humibacter albus gen. nov., sp. nov., isolated from sewage sludge compost
Vaz-Moreira, Ivone; Nobre, M. Fernanda; Ferreira, António C. SilvaA bacterial strain isolated from sewage sludge compost, strain SC-083T, was characterized. The isolate was a motile, Gram-positive, short rod, forming coryneform V-shaped cells during the early stages of growth. The organism was strictly aerobic and able to grow between 22 and 36 °C and between pH 5.5 and 8.0. The predominant fatty acids were cyclohexyl-C17 : 0, anteiso-C17 : 0 and iso-C16 : 0, the major respir...
Pseudosphingobacterium domesticum gen. nov., sp. nov., isolated from home-made ...
Manaia, Célia M.; Vaz-Moreira, Ivone; Nobre, M. Fernanda; Nunes, Olga C.A bacterial strain, DC-186T, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 6C and pH 5.5–8.0. Strain DC-186T was positive in tests for catalase, oxidase and b-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C16 : 1/iso-C15 : 0 2-OH (42 %) a...
Paenibacillus humicus sp. nov., isolated from poultry litter compost
Vaz-Moreira, Ivone; Faria, Cátia; Nobre, M. Fernanda; Schumann, Peter; Nunes, Olga C.; Manaia, Célia M.Two bacterial strains, PC-142 and PC-147T, isolated from poultry litter compost, were characterized with respect to their phenetic and phylogenetic characteristics. The isolates were endospore-forming rods that were reddish in colour after Gram staining. They were catalaseand oxidase-positive, were able to degrade starch and gelatin and grew at 15–40 6C and pH 5.5–10.0. The predominant fatty acids were anteiso-...
Gulbenkiania mobilis gen. nov., sp. nov., isolated from treated municipal waste...
Vaz-Moreira, Ivone; Nobre, M. Fernanda; Nunes, Olga C.; Manaia, Célia M.A bacterial strain (E4FC31T) isolated from treated municipal wastewater was characterized phenotypically and phylogenetically. Cells were Gram-negative, curved rods with a polar flagellum. The isolate was catalase-, oxidase- and arginine dihydrolase-positive, and able to grow between 15 and 45 6C and between pH 5.5 and 9.0. The predominant fatty acids were C16 : 1/iso-C15 : 0 2-OH and C16 : 0, the major respira...
