| psychrophilic pseudomonads from antarctica: pseudomonas antarctica sp. nov., pseudomonas meridiana sp. nov. and pseudomonas proteolytica sp. nov. | thirty-one bacteria that belonged to the genus pseudomonas were isolated from cyanobacterial mat samples that were collected from various water bodies in antarctica. all 31 isolates were psychrophilic; they could be divided into three groups, based on their protein profiles. representative strains of each of the three groups, namely cms 35(t), cms 38(t) and cms 64(t), were studied in detail. based on 16s rrna gene sequence analysis, it was established that the strains were related closely to the ... | 2004 | 15143013 |
| diversity and antagonistic activity of sea ice bacteria isolated from the sea of japan. | the aim of the study was to survey cultivable heterotrophic bacteria from sea ice samples collected from peter the great bay of the sea of japan, and to test the isolates for antagonistic activity. a total of 195 strains were isolated and investigated by a phenotypic approach. the 16s rrna gene sequence analysis of thirty eight strains revealed primarily representatives of the class gammaproteobacteria, phylum bacteroidetes, and phylum actinobacteria. members of the class alphaproteobacteria wer ... | 2008 | 21558710 |
| protease and lipase activities of fungal and bacterial strains derived from an artisanal raw ewe's milk cheese. | we previously identified the microbiota present during cheese ripening and observed high protease and lipase activity in divle cave cheese. to determine the contribution of individual isolates to enzyme activities, we investigated a range of species representing this microbiota for their proteolytic and lipolytic ability. in total, 17 fungal, 5 yeast and 18 bacterial strains, previously isolated from divle cave cheese, were assessed. qualitative protease and lipase activities were performed on s ... | 2016 | 27541978 |
| possible misidentification of species in the pseudomonas fluorescens lineage as burkholderia pseudomallei and francisella tularensis, and emended descriptions of pseudomonas brenneri,pseudomonas gessardii and pseudomonas proteolytica. | bacteria were isolated from an industrial water circuit in the netherlands. these strains were identified using api 20 ne as possible, or likely, burkholderia pseudomallei. with vitek 2 some of these strains scored 'low discrimination' for francisella tularensis, amongst others. a total of twenty-six strains were assigned to the species pseudomonas brenneri, pseudomonas gessardii or pseudomonas proteolytica. because of the possibility of misidentification of these environmental species as medica ... | 2016 | 27259517 |
| prolonged production and aggregation complexity of cold-active lipase from pseudomonas proteolytica (gbpi_hb61) isolated from cold desert himalaya. | pseudomonas, being the common inhabitant of colder environments, are suitable for the production of cold-active enzymes. in the present study, a newly isolated strain of pseudomonas from cold desert site in indian himalayan region, was investigated for the production of cold-active lipase. the bacteria were identified as pseudomonas proteolytica by 16s rdna sequencing. lipase production by bacteria was confirmed by qualitative assay using tributyrin and rhodamine-b agar plate method. the bacteri ... | 2017 | 28013401 |
| effects of illuminance and nutrients on bacterial photo-physiology of hydrocarbon degradation. | bacterial photophysiology was previously limited to photoautotrophs. the discovery of bacteriophytochromes in non-photoautotrophs raised a question whether these non-photoautotrophs are affected by the presence or absence of light? in this research work for the first time, bacterial hydrocarbon degradation and biomass production was studied under the influence of nutrients, illuminance (light flux) and time. an experimental model was designed, with six isolated bacterial strains (pseudomonas poa ... | 2016 | 27039061 |
