Summary In this study, we redesigned and evaluated primers for the class Actinobacteria . silico testing showed that had a perfect match with 82% of genera in , representing 26–213% improvement over previously reported primers. Only 4% displayed mismatches did so terminal three bases 3′ end, which is most critical polymerase chain reaction success. The primers, designated S‐C‐Act‐0235‐a‐S‐20 S‐C‐Act‐0878‐a‐A‐19, amplified an ≈ 640 bp stretch 16S rRNA gene from all actinobacteria tested...
A taxonomic study was carried out to clarify the taxonomy of representatives a group marine actinomycetes previously designated MAR 1 and considered belong family Micromonosporaceae . The organisms had phenotypic properties consistent with their assignment this taxon. strains formed distinct taxon in 16S rRNA gene tree shared range that distinguished them from members all genera validly published names classified family. name proposed for novel is Salinispora gen. nov. genus contains two...
ABSTRACT Bacterial diversity in a deep-sea sediment was investigated by constructing actinobacterium-specific 16S ribosomal DNA (rDNA) clone libraries from sections taken 5 to 12, 15 18, and 43 46 cm below the sea floor at depth of 3,814 m. Clones were placed into operational taxonomic unit (OTU) groups with ≥99% rDNA sequence similarity; cutoff value for an OTU derived comparing rRNA homology DNA-DNA reassociation values members class Actinobacteria. Diversity statistics used determine how...

En cursos de métodos estadísticos avanzados, habitualmente son utilizados textos econométricos como principal referencia. Sin embargo, econometría es sólo una perspectiva a partir la cual se puede aprender estadística. Una alternativa ofrece disciplina estadística misma, en donde conceptos tales variabilidad los coefi cientes, incerteza torno dicha o simulación, uso común actualidad. Lamentablemente, discusión dichos frecuentemente planteada términos altamente matemáticos, lo hace difícil el...
Marine bacteria are considered as promising sources for the discovery of novel biologically active compounds. In this study, samples sediment, invertebrate and algae were collected from Providencia Santa Catalina coral reef (Colombian Caribbean Sea) with aim isolating Actinobateria-like strain able to produce antimicrobial quorum quenching compounds against pathogens. Several approaches used select actinobacterial isolates, obtaining 203 strains all samples. According their 16S rRNA gene...
Abstract. Atmospheric aerosol particles that can nucleate ice are referred to as ice-nucleating (INPs). Recent studies have confirmed emitted by the oceans act INPs. This very relevant information be included in climate and weather models predict formation of clouds, given most them do not consider a source Very few sample INPs been carried out tropical latitudes, there is need evaluate their availability understand potential role marine may play hydrological cycle regions. study presents...
The taxonomic status of a soil isolate, provisionally assigned to the genus Nocardia, was established following polyphasic study. An almost complete sequence 16S rDNA strain determined and aligned with available sequences for nocardiae phylogenetic trees were inferred using four tree-making algorithms. organism associated consistently type strains Nocardia brasiliensis farcinica in neighbour-joining analysis, albeit low bootstrap values. It also found have chemotaxonomic morphological...
Eight actinomycete strains, isolated from 8 out of 400 sputum samples examined, taken patients with pulmonary diseases at the Chest Unit Khartoum Teaching Hospital in Sudan, were provisionally assigned to genus Nocardia according morphological criteria. These isolates studied further order establish their taxonomic status. They found have and chemical properties typical nocardiae formed a monophyletic clade 16S ribosomal DNA tree together vaccinii. The strains showed unique pattern...
An isolate from Cerrado soil, provisionally assigned to the genus Nocardia, was shown have chemical and morphological properties typical of nocardiae. The strain formed a distinct monophyletic clade in 16S rDNA tree together with Nocardia africana, vaccinii veterana, showed unique combination phenotypic that distinguished it representatives all recognized species Nocardia. DNA–DNA relatedness studies indicated belongs genomic is readily its nearest neighbours, type strains N. africana...
The taxonomic position of a marine actinomycete, strain SJS0289/JS1 T , was determined using polyphasic approach. organism, which had phenotypic properties consistent with its classification in the genus Williamsia formed distinct clade 16S rRNA gene tree together type muralis but readily distinguished from this species DNA–DNA relatedness and data. genotypic data show that organism merits recognition as new . name proposed for is maris ; (=DSM 44693 =JCM 12070 =KCTC 9945 =NCIMB 13945 ).
A polyphasic study was undertaken to clarify the taxonomic position of Nonomuraea flexuosa DSM 41386 T .
