A novel 3D metal-organic framework (MOF) with 2D rhombic channels was synthesized for selective adsorption of p-xylene from xylene isomers by acting as a molecular sieve.
The formation water of a deep aquifer (853 m of depth) used for geological storage of natural gas was sampled to assess the mono-aromatic hydrocarbons attenuation potential of the indigenous microbiota. The study of bacterial diversity suggests that Firmicutes and, in particular, sulphate-reducing bacteria (Peptococcaceae) predominate in this microbial community. The capacity of the microbial c...
The far-ranging distribution of genes for aromatic hydrocarbon catabolism, predominantly studied in soil pseudomonads, is extended to a marine oligobacterium by finding five homologous sequences in a 5.7-kb chromosomal DNA from a new isolate, Cycloclasticus oligotrophus RB1. RB1 is capable of growth in unamended seawater or mineral salts media supplemented with a variety of aromatic compounds, ...
More than one hundred volatile organic substances were identified by gas chromatography and mass spectrometry (GC/MS) in the indoor and outdoor air, stable and farm road dust and farm soil samples from two pig and cattle farms in the South Moravian Region. Volatile fatty acids (acetic, propanoic, butanoic and pentanoic acids) and their esters dominated along with aldehydes (butanal, pentanal an...
