Microbial structuring of marine ecosystems (2007, background): “Most (90–95%) of the DOM is refractory to degradation by bacteria and it has been proposed that some DOM components serve as stable scaffolds of a gel architecture that is inaccessible to bacterial ectohydrolase”
Microbial degradation of peptidoglycan in seawater (2003, positive): “Furthermore, recent studies have failed to detect high concentrations of muramic acids, an amino sugar that exclusively occurs in peptidoglycan, in marine DOM (Kaiser and Benner 2000; Benner and Kaiser 2003) and in a refractory component of DOM produced by bacteria (Ogawa et al. 2001).”
Mesopelagic zone ecology and biogeochemistry - a synthesis (2010, background): “This semi-labile fraction enters the deep ocean via convective overturn (Carlson et al., 1994; Hansell and Carlson, 2001), isopycnal exchange (Hansell et al., 2002) or in situ production (Ogawa et al., 2001).”
Dissolved organic nitrogen: a dynamic participant in aquatic ecosystems (2003, background): “Recent studies of this fraction suggest that much of the refractory DON in the oceans probably consists of amide groups in peptidoglycan remnants enriched with D-enantiomers of alanine, asparagine, glutamic acid, and serine (McCarthy et al. 1996, 1997, 1998, Dittmar et al. 2001, Ogawa et al. 2001).”
Biogeneration of chromophoric dissolved organic matter by bacteria and krill in the Southern Ocean (2009, background): “2007), to refractory material (Ogawa et al. 2001), a feature that appears to be dependent on nitrogen availability (Biers et al.”
Photo- and bioreactivity of chromophoric dissolved organic matter produced by marine bacterioplankton (2004, methodology): “Ogawa et al. (2001) showed in laboratory experiments that only 30% of the bacterial-derived DOM is hydrolyzable and, therefore, accessible for analysis on a molecular level.”
The microbial carbon pump and the oceanic recalcitrant dissolved organic matter pool (2011, background): “Therefore, the recalcitrance of DOM cannot simply be defined by age; it can be defined structurally (using molecular characteristics, for example) or experimentally (using bioassays”
Microbial Extracellular Polymeric Substances (EPSs) in Ocean Systems (2017, background): “Extracellular polymeric substance produced by marine bacteria, even that which is freshly produced, can be somewhat refractory to microbial degradation or chemical analysis (Ogawa et al., 2001).”
LAMPENFLORA ALGAE AND METHODS OF GROWTH CONTROL (2009, background): “…not observed in water samples because biomolecules are more susceptible to enzymatic attack relative to more refractory fulvic acids (e.g., Moran and Hodson, 1990; Claus et al., 1999; Ogawa et al., 2001; Hertkorn et al., 2002; Yamashita and Tanoue, 2003; Anesio et al., 2004; Judd et al., 2006).”
Response of soil dissolved organic matter to microplastic addition in Chinese loess soil. (2017, background): “The labile fractions of DOM, such as carbohydrates, are preferentially degraded by microorganisms, so refractory DOM primarily accumulates during biodegradation (Ogawa et al., 2001; Kalbitz et al., 2003a, 2003b).”
Water residence time: A regulatory factor of the DOM to POM transfer efficiency (2007, background): “2001) leading to the production of recalcitrant DOM (Ogawa et al. 2001).”
Composition analysis of organic matter released by cosmopolitan coral reef-associated green algae (2010, background): “Other dissolved monosaccharides, especially the more refractory deoxysugars, play a rather subordinate role in heterotrophic bacterial production (Amon et al. 2001, Ogawa et al. 2001).”
The roles of microorganisms in litter decomposition and soil formation (2014, background): “In addition, highly decomposed marine organic matter typically exhibits low GlcN/GalN ratios (Ogawa et al. 2001; Benner and Kaiser 2003; Kaiser and Benner 2009).”
