Environmental Effects on Gross Production and Respiration in a Facultative Oxidation Pond [PDF]

, 1986
Oxygen exchange by effluent samples taken at weekly intervals from a facultative oxidation pond was investigated over a 7 month period. Concentrations of ammonia, nitrate, nitrite, total and reactive phosphorus, alkalinity, total inorganic carbon, and ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Petri Nets Hierarchical Modelling Framework of Active Products' Community

, 2010
In this work, we define the concept of an active security management in a distributed system, with Hierarchical Petri nets modelling of active product's behaviour. The target application is dedicated to security management of hazardous products but the concept is extensible to other application areas.

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Phytoplankton physiology and functional traits under artificial upwelling with varying Si:N

Frontiers in Marine Science
IntroductionArtificial upwelling has been discussed as a nature-based solution to fertilize currently unproductive areas of the ocean to enhance food web productivity and atmospheric CO2 sequestration. The efficacy of this approach may be closely tied to

Mechanisms controlling the air-sea CO2 flux in the North Sea [PDF]

, 2009
The mechanisms driving the air–sea exchange of carbon dioxide (CO2CO2) in the North Sea are investigated using the three-dimensional coupled physical–biogeochemical model ECOHAM (ECOlogical-model, HAMburg).

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.
