Background. The anaerobic gut fungi (phylum Neocallimastigomycota) represent a promising source of novel lignocellulolytic enzymes. Here, we report on the cloning, expression, and characterization of a glycoside hydrolase family 39 (GH39) enzyme (Bgxg1) that is...

Zeta potential, defined as the electric charge at the shear plane, is widely used as a proxy for bacteria cell surface charge. Nonspecific adsorption of ions or polyelectrolytes onto the cell surface, however, alters the value and polarity of the measured zeta...

Environmental stresses select for suitably adapted genes. These stresses will promote the propagation of certain mutations, and the loss of others, throughout the evolution of a species. For organisms living two thousand meters below the ocean’s surface, one of...

Rhamnolipids are biosurfactants with potential for diversified industrial and environmental uses. The present study evaluated three strategies for increasing the production of rhamnolipid-type biosurfactants produced by Pseudomonas aeruginosa strain PA1. The influence...

Background. How host-symbiont interactions coevolve between mutualism and parasitism depends on the ecology of the system and on the genetic and physiological constraints of the organisms involved. Theory often predicts that greater reliance on horizontal transmission...

The majority of bacterial genome annotations are currently automated and based on a ‘gene by gene’ approach. Regulatory signals and operon structures are rarely taken into account which often results in incomplete and even incorrect gene function assignments. Here...

Barbiturases have scarce structural information available and do not fit in the conventional group of proteins. It is contemplated that they play a role in catabolism of s-triazine herbicide compounds. Structure as well as interaction data information of barbiturase...

Mementos encapsulate memories and serve as triggers for their recollections. By using a purple pigment producing bacterium as “ink” for writing on agar, a picture memento depicting the initials of students’ names was created to help them remember the strong friendships...

Aeromonas salmonicida subsp. salmonicida, the causative agent of furunculosis in salmonids, is an issue especially because many isolates of this bacterium display antibiotic resistances, which limit treatments against the disease. Recent results suggested the possible...

Numerous investigations of bacterial communities using sequence analysis of environmental DNA have revealed extensive diversity of microbial taxa in an array of different environmental habitats. Community analysis based solely on DNA, however, does not reveal whether...

A lab-scale biofilter packed with mixed packing materials was used for degradation of toluene. Different empty bed residence times, 148.3, 74.2 and 49.4 s, were tested for inlet concentration ranging from 0.2 to 1.2 g/m3. The maximum elimination capacity of 36.0...

Permafrost stores approximately 50% of global soil carbon (C) in a frozen form; it is thawing rapidly under climate change, and little is known about viral communities in these soils or their roles in C cycling. In permafrost soils, microorganisms contribute significantly...

Solid medium enables spatially resolved simultaneous cultivation of different microbes in a simple and relatively low cost format useful for preliminary screening of microbial diversity. Lack of colour contrast between colonies and agar, however, hampers colony...

Bacterial surface charge mediates important cell-environment and microbe-host interactions, and its accurate and precise measurement by microelectrophoresis requires removing metabolites adhered to the cell surface - where repeated centrifugation and washing by...
