Corrigendum: Bacterial growth and mortality after deposition of saharan dust and mixed aerosols in the eastern mediterranean sea: A mesocosm experiment ; Bacterial Growth and Mortality after Deposition of Saharan Dust and Mixed Aerosols in the Eastern Mediterranean Sea: A Mesocosm Experiment
WOS: 000457690200007 ; Science Citation Index Expanded ; The impact of viral lysis and grazing by flagellates on bacterioplankton production was assessed during a mesocosm experiment in the Eastern Mediterranean Sea, in response to Saharan dust (SD) vs. mixed aerosols (A) addition. The results highlight a positive effect on bacterial abundance, production and growth rate (similar to 1.2, similar to 2.4, and similar to 1.9-fold higher than the controls) in both SD and A, which was also confirmed by the increased portion of high DNA content bacteria (up to 48% of the bacterial community). Lytic viral production and the portion of bacterial production lost due to viral lysis were lower in SD and A after dust addition than in the controls (0.33 +/- 0.17 x 10(6) virus-like particles mL(-1) h(-1) and 6 +/- 4%, respectively). Potential ingestion rate of bacteria by flagellates increased upon dust enrichment, but did not differ between mesocosms. Larger predators possibly down regulated flagellate abundance, and the calculated portion of bacterial production lost due to flagellate grazing was probably an artifact. Higher frequency of lysogenic cells in A compared to SD and the controls four days after dust addition may reflect faster phosphorus limitation in A, due to receiving less dissolved inorganic phosphorus and more dissolved inorganic nitrogen than SD. ; European Union [228224]; project ADAMANT: Atmospheric deposition and Mediterranean sea water productivity [MIS: 383551]; European Union (European Social Fund-ESE); Greek national funds through the Operational Program "Education and Lifelong Learning" of the National Strategic Reference Framework (NSRF) (Research Funding Program: THALES) ; This study was funded by the European Union 7th Framework Program (FP7/2007-2013) under grant agreement no. 228224, "MESOAQUA: Network of leading MESOcosm facilities to advance the studies of future AQUAtic ecosystems from the Arctic to the Mediterranean" and by the project ADAMANT: Atmospheric deposition and Mediterranean sea ...
