Enrichment of PCB dechlorinating bacteria from marine sediments of Venice lagoon under geochemical conditions that mime those occurring in situ.
No full textReductive dechlorination of PCBs has been reported in a number of slurry and sediment-free cultures from freshwater habitats established with defined mineral media, and was recently ascribed to bacteria of a dechlorinating clade within the phylum Chloroflexi. In this work, we enriched and characterized the PCB dechlorinating microbial population from a contaminated marine sediment suspended in its own site water. The enriched cultures were capable of rapidly and extensively dechlorinating the commercial mixture of PCBs Aroclor 1254 at the meta and para positions according to the dechlorination pattern H’. PCR-DGGE and quantitative PCR analyses on 16S rRNA genes revealed that a single Chloroflexi phylotype having 100% sequence identity with bacterium m-1 was enriched

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
