Bacteria that produce inhibitory compounds on the surface of marine algae are thought to contribute to the defense of the host plant against colonization of fouling organisms. However, the number of bacterial cells necessary to defend against fouling on the plant surface is not known. Pseudoalteromonas tunicata and Phaeobacter sp. strain 2.10 (formerly(More)
Chloroform (CF, CHCl(3)) is a recalcitrant and toxic environmental pollutant. In this communication we report for the first time a microbial community capable of complete CF dechlorination by metabolic processes. Cultures derived from subsurface soil (3.5 m) could sustain complete dechlorination of CF at levels of least 360 µM at a rate of 40 µM per day.(More)
Host-pathogen interactions have been widely studied in humans and terrestrial plants, but are much less well explored in marine systems. Here we show that a marine macroalga, Delisea pulchra, utilizes a chemical defence - furanones - to inhibit colonization and infection by a novel bacterial pathogen, Ruegeria sp. R11, and that infection by R11 is(More)
We present a new approach for the recognition of facial expressions from video sequences in the presence of occlusion. Although promising results have been reported in the literature on automatic recognition of facial expressions, most techniques have been assessed using experiments performed in controlled laboratory conditions which do not reflect(More)
Microbial community compositions were determined for three soil horizons and drain sediments within an anthropogenically disturbed coastal acid sulfate landscape using 16S rRNA gene tagged 454 pyrosequencing. Diversity analyses were problematic due to the high microbiological heterogeneity between each geochemical replicate. Taxonomic analyses combined with(More)
A reactive iron barrier in a contaminated aquifer with low pH was found to dechlorinate 1,2-dichloroethane (1,2-DCA) in situ. This chlorinated ethane is known to resist abiotic reduction by zero valent iron. Samples taken up-gradient and within the barrier were used to inoculate anaerobic batch cultures amended with various electron donors. Cultures(More)
1,2-dichloroethane (DCA) is a problematic groundwater pollutant. Factors influencing the distribution and activities of DCA-degrading bacteria are not well-understood, which has hampered their application for bioremediation. Here, we used quantitative PCR (qPCR) to investigate the distribution of putative DCA-dehalogenating bacteria at a DCA-impacted site(More)
