Determining the influence of environmental and patient specific factors on the polymicrobial communities of the cystic fibrosis airway

25.11.2012 | Andrew Nelson, Audrey Perry, John D. Perry, Stephen J. Bourke, Stephen P. Cummings, Anthony De Soyza, Antonie van Leeuwenhoek, 2012

The aim of this study was to investigate the polymicrobial communities in an adult Cystic Fibrosis population stratified by gender and the most common CFTR mutation, F508del. In this pilot study, DNA was extracted from sputum samples of 29 adult patients (16 male: 13 female) with an F508del ...

The acid tolerant and cold-active β-galactosidase from Lactococcus lactis strain is an attractive biocatalyst for lactose hydrolysis

25.11.2012 | Violette Vincent, Nushin Aghajari, Noémie Pollet, Anaïs Boisson, Samira Boudebbouze, Richard Haser, Emmanuelle Magui ..., Antonie van Leeuwenhoek, 2012

The gene encoding the β-galactosidase from the dairy Lactococcus lactis IL1403 strain was cloned, sequenced and overexpressed in Escherichia coli. The purified enzyme has a tetrameric arrangement composed of four identical 120 kDa subunits. Biochemical characterization showed that it is optimally ...

Two Trichosporon species isolated from Central-European mygalomorph spiders (Araneae: Mygalomorphae)

25.11.2012 | Petr Heneberg, Milan Řezáč, Antonie van Leeuwenhoek, 2012

Trichosporon (Dikarya: Basidiomycota) is a genus of anamorphic yeasts typically associated with soil and water, although many species are causative agents of diseases in animals and man. Here we provide the first compelling evidence that spiders can be occasionally colonized by at least two ...

A novel killer toxin produced by the marine-derived yeast Wickerhamomyces anomalus YF07b

25.11.2012 | Feng-Jun Guo, Yan Ma, Hong-Mei Xu, Xiang-Hong Wang, Zhen-Ming Chi, Antonie van Leeuwenhoek, 2012

In our previous study, it was found that the killer toxin produced by the marine-derived yeast Wickerhamomyces anomalus YF07b has both killing activity and β-1,3-glucanase activity and the molecular mass of it is 47.0 kDa. In this study, the same yeast strain was found to produce another killer ...

Paenibacillus brassicae sp. nov., isolated from cabbage rhizosphere in Beijing, China

25.11.2012 | Miao Gao, Hui Yang, Ji Zhao, Jun Liu, Yan-hua Sun, Yu-jiong Wang, Jian-guang Sun, Antonie van Leeuwenhoek, 2012

A novel Gram-positive, rod-shaped, motile, spore-forming, nitrogen-fixing bacterium, designated strain 112T, was isolated from cabbage rhizosphere in Beijing, China. The strain was found to grow at 10–40 °C and pH 4–11, with an optimum of 30 °C and pH 7.0, respectively. Phylogenetic analysis ...

Bioprospecting of thermo- and osmo-tolerant fungi from mango pulp–peel compost for bioethanol production

25.11.2012 | N. D. Dandi, B. N. Dandi, A. B. Chaudhari, Antonie van Leeuwenhoek, 2012

The persistent edaphic stress on microbial succession due to dynamic changes during composting was explored for selection of multi-stress tolerant microbe(s) desirable for ethanol production. A total of 23 strains were isolated from mango compost using four successive enrichments in YP broth (g ...

Amycolatopsis umgeniensis sp. nov., isolated from soil from the banks of the Umgeni River in South Africa

25.11.2012 | Gareth J. Everest, Marilize le Roes-Hill, Clifford Omorogie, Shuk-Kwan Cheung, Andrew E. Cook, Candice M. Goodwin, P ..., Antonie van Leeuwenhoek, 2012

A novel member of the genus Amycolatopsis was isolated from soil collected from the banks of the Umgeni River, KwaZulu Natal province, South Africa. The strain, designated UM16T, grouped with the type strains of Amycolatopsis alba, Amycolatopsis coloradensis and Amycolatopsis thailandensis by 16S ...

Prescottia equi gen. nov., comb. nov.: a new home for an old pathogen

19.11.2012 | Amanda L. Jones, Iain C. Sutcliffe, Michael Goodfellow, Antonie van Leeuwenhoek, 2012

The taxonomic status of Rhodococcus equi, originally isolated from foal specimens, has been the subject of discussion for a number of years. The chequered history of the taxon has prompted this polyphasic analysis of R. equi strains, close members of the genus Rhodococcus and representatives of ...

Roseomonas musae sp. nov., a new bacterium isolated from a banana phyllosphere

09.11.2012 | Pumin Nutaratat, Nantana Srisuk, Kannika Duangmal, Hiroya Yurimoto, Yasuyoshi Sakai, Yuki Muramatsu, Yasuyoshi Nakagawa, Antonie van Leeuwenhoek, 2012

A Gram-negative, coccobacilli, non-spore forming and non-motile bacterium, designated PN1T, was isolated from a banana leaf collected in Mattra island, Thailand. This isolate was observed to grow optimally at 30 °C and pH 7.0, and to grow with 0–3 % NaCl. Comparative 16S rRNA gene sequence ...
