Effect of environmental variables on eukaryotic microbial community structure of land-fast Arctic sea ice.

abstract：:The well-known role of antibiotics in killing sensitive organisms has been challenged by the effects they exert at subinhibitory concentrations. Unfortunately, there are very few published reports on the advantages these molecules may confer to their producers. This study describes the construction of a genetically ve...
