[HTML][HTML] Bioinformatic approaches reveal metagenomic characterization of soil microbial community

Z Xu, MA Hansen, LH Hansen, S Jacquiod… - PloS one, 2014 - journals.plos.org
As is well known, soil is a complex ecosystem harboring the most prokaryotic biodiversity on
the Earth. In recent years, the advent of high-throughput sequencing techniques has greatly …

[HTML][HTML] Hundreds of circular novel plasmids and DNA elements identified in a rat cecum metamobilome

…, Z Xu, MA Hansen, SJ Sørensen, LH Hansen - PloS one, 2014 - journals.plos.org
Metagenomic approaches are widespread in microbiological research, but so far, the knowledge
on extrachromosomal DNA diversity and composition has largely remained dependant …

[HTML][HTML] Complete Genome Sequence of the Cystic Fibrosis Pathogen Achromobacter xylosoxidans NH44784-1996 Complies with Important Pathogenic Phenotypes

TH Jakobsen, MA Hansen, PØ Jensen, L Hansen… - PloS one, 2013 - journals.plos.org
Achromobacter xylosoxidans is an environmental opportunistic pathogen, which infects an
increasing number of immunocompromised patients. In this study we combined genomic …

Sequentially aerated membrane biofilm reactors for autotrophic nitrogen removal: microbial community composition and dynamics

…, A Terada, WA Al‐Soud, MA Hansen… - Microbial …, 2014 - Wiley Online Library
Membrane‐aerated biofilm reactors performing autotrophic nitrogen removal can be successfully
applied to treat concentrated nitrogen streams. However, their process performance is …

Maize lines with different nitrogen use efficiency select bacterial communities with different β-glucosidase-encoding genes and glucosidase activity in the rhizosphere

SI Pathan, MT Ceccherini, MA Hansen… - Biology and fertility of …, 2015 - Springer
We studied the molecular diversity of β-glucosidase-encoding genes, microbial biomass,
cellulase, N-acetyl-glucosaminidase, β-glucosidase, and β-galactosidase activities in the …

Identification of genes differentially expressed in testes containing carcinoma in situ

CE Hoei‐Hansen, JE Nielsen… - Molecular human …, 2004 - academic.oup.com
Virtually all testicular germ cell tumours originate from a common precursor, the carcinoma
in situ (CIS) cell. The precise nature of the molecular mechanisms leading to CIS remains …

Adaptation and heterogeneity of Escherichia coli MC1000 growing in complex environments

PE Puentes-Téllez, MA Hansen… - Applied and …, 2013 - Am Soc Microbiol
In a study aiming to assess bacterial evolution in complex growth media, we evaluated the
long-term adaptive response of Escherichia coli MC1000 in Luria-Bertani (LB) medium. …

Plasmid metagenomics reveals multiple antibiotic resistance gene classes among the gut microbiomes of hospitalised patients

…, S Tangphatsornruang, MA Hansen, LH Hansen… - Journal of Global …, 2016 - Elsevier
Antibiotic resistance genes are rapidly spread between pathogens and the normal flora,
with plasmids playing an important role in their circulation. This study aimed to investigate …

Germ cell differentiation-dependent and stage-specific expression of LANCL1 in rodent testis

JE Nielsen, MA Hansen, M Jà- European Journal of Histochemistry, 2003 - ejh.it
LANCL1 (LanC-like protein 1) is related to the bacterial LanC (lanthionine synthetase C) family,
which is involved in the biosynthesis of antimicrobial peptides. Highest expression levels …

Plasmids, viruses, and other circular elements in rat gut

TS Jørgensen, MA Hansen, Z Xu, MA Tabak… - bioRxiv, 2017 - biorxiv.org
Circular DNA such as plasmids and some viruses is the major source of genetic variation in
bacteria and thus has the same important evolutionary function as sexual reproduction in …
