'The ability of marine bacteria to adhere to detrital particulate organic matter and rapidly switch on metabolic genes in an effort to reproduce is an important response for bacterial survival in the pelagic marine environment. The goal of this investigation was to evaluate the relationship between chitinolytic gene expression and ... More
Characterization of extracellular chitinolytic activity in biofilms.
'Extracellular enzymes produced by bacterial biofilms tend to become an integral, permanent part of the biofilm/substratum system. Thus, characterizing extracellular enzyme activity is an essential component of understanding biofilm ecology. Methods have been presented for characterizing three aspects of extracellular enzyme activity in biofilms: promoter activity of the structural gene, ... More
Spatial and temporal variations in chitinolytic gene expression and bacterial biomass production during chitin degradation.
Growth of the chitin-degrading marine bacterium S91 on solid surfaces under oligotrophic conditions was accompanied by the displacement of a large fraction of the surface-derived bacterial production into the flowing bulk aqueous phase, irrespective of the value of the surface as a nutrient source. Over a 200-h period of surface ... More
