abstract
Faecal pellets make up a significant fraction of the global flux of organic matter in oceans, and the associated bacterial communities in particular are a potential food source for marine organisms. However, these communities remain largely unknown. In the present study the bacterial communities on faecal pellets of the benthic copepod Paramphiascella fulvofasciata feeding on the diatoms Navicula phyllepta and Seminavis robusta were analysed. The aim of this study was to characterize the bacterial communities associated with the diatoms and the faecal pellets by means of DGGE profiling. Furthermore, isolated bacteria were characterised by means of partial 16S rRNA gene sequencing. The composition of the bacterial microflora on faecal pellets was studied in terms of the effect of the original food source, the age of the faecal pellets and the copepod’s identity. Alphaproteobacteria, Flavobacteria and Bacilli were found on the faecal pellets, whereas on diatoms exclusively Gammaproteobacteria were identified. Especially after eating N. phyllepta, there was an important increase in bacterial diversity, although the diatom N. phyllepta harboured a less diverse bacterial community than S. robusta. Our data suggest that the additional bacteria originates from the copepod’s digestive tract and largely depends on the initial food source.
