A revised stratigraphy for the Palaeocene Agatdalen flora (Nuussuaq Peninsula, western Greenland): correlating fossiliferous outcrops, macrofossils, and palynological samples from phosphoritic nodules

Acta Palaeobotanica, 2016
The Cretaceous and Palaeogene floras of western Greenland that were initially described as part of the classical work “Flora fossilis arctica” by Oswald Heer in the 19th century are currently under revision.

Spore Germination

Microbiology Spectrum, 2015
ABSTRACT Despite being resistant to a variety of environmental insults, the bacterial endospore can sense the presence of small molecules and respond by germinating, losing the specialized structures of the dormant spore, and resuming active metabolism, before outgrowing into vegetative cells.

The triterpenoid curcumene mediates the relative hydrophilicity of Bacillus subtilis spores

mBio
Spores of Bacillus subtilis are surrounded and protected by the coat and the crust, multi-layered structures mainly made of proteins and polysaccharides.

Rapid, Point-of-Care Microwave Lysis and Electrochemical Detection of Clostridioides difficile Directly from Stool Samples

Bioengineering
The rapid detection of the spore form of Clostridioides difficile has remained a challenge for clinicians. To address this, we have developed a novel, precise, microwave-enhanced approach for near-spontaneous release of DNA from C. difficile spores via a

Co‐purification of nitrate reductase 1 with components of the cytochrome bcc‐aa3 oxidase supercomplex from spores of Streptomyces coelicolor A3(2)

FEBS Open Bio, 2021
In order to reduce nitrate in vivo, the spore‐specific respiratory nitrate reductase, Nar1, of Streptomyces coelicolor relies on an active cytochrome bcc‐aa3 oxidase supercomplex (bcc‐aa3 supercomplex).

Inactivation Effect of Thymoquinone on Alicyclobacillus acidoterrestris Vegetative Cells, Spores, and Biofilms

Frontiers in Microbiology, 2021
Alicyclobacillus acidoterrestris (A. acidoterrestris), a spore-forming bacterium, has become a main challenge and concern for the juices and acid beverage industry across the world due to its thermo-acidophilic characteristic. Thymoquinone (TQ) is one of

Mycological analysis of air in selected rooms of the University of Szczecin – a pilot project

Acta Agrobotanica, 2014
Aerobiological measurements were made by the volumetric method (VPPS Lanzoni and Burkard instruments). Concentrations of microscopic fungi were measured from April 16th to July 2nd, 2013, in two rooms of the Chair of Botany and Natural Environment ...
