“…Marine detritus includes a component of reworked organic matter with lower nutritional values than extant biomass (e.g. Dauwe et al 1999), which is not available for direct use and transfer through the marine trophic web (Mann 1988, Lopez & Levinton 2011. Our data on organic and elemental composition of selected strains suggest that marine fungi are rich in essential molecules, have a relatively high energetic content, and have lower C to N molar ratios than marine algae.…”

Fungi are ubiquitous in the marine environment, but their role in carbon and nitrogen cycling in the ocean, and in particular the quantitative significance of fungal biomass to ocean biogeochemistry, has not yet been assessed. Determination of the biochemical and stable isotope composition of marine fungi can provide a basis for identifying fungal patterns in relation to other microbes and detritus, and thus allow evaluation of their contribution to the transformation of marine organic matter. We characterized the biochemical composition of 13 fungal strains isolated from distinct marine environments in the eastern South Pacific Ocean off Chile. Proteins accounted for 3 to 21% of mycelial dry weight, with notably high levels of the essential amino acids histidine, threonine, valine, lysine and leucine, as well as polyunsaturated fatty acids, ergosterol, and phosphatidylcholine. Elemental composition and energetic content of these marine-derived fungi were within the range reported for bacteria, phytoplankton, zooplankton and other metazoans from aquatic environments, but a distinct pattern of lipids and proteins was identified in marine planktonic fungi. These biochemical signatures, and an elemental composition indicative of a marine planktonic source, have potential applications for the assessment of fungal contribution to marine microbial biomass and organic matter reservoirs, and the cycling of carbon and nutrients.

“…A study examining seasonal variation of EHAA in the seston of the Damariscotta estuary found the EHAA consisted of varying combinations of live phytoplankton and phytoplankton-derived detritus, or phytodetritus (Laursen et al 1996). Phytodetritus is particularly nutritious relative to other detrital particles and may be able to provide an ephemeral but significant amount of nutrition to filter feeders, especially between phytoplankton blooms (Lopez & Levinton 2011).…”

“…Bodemetende bodemdieren worden niet (direct) beïnvloed door fytoplankton omdat ze detritus eten en meer afhankelijk zijn van de flux van detritus naar de bodem. Bodemetende bodemdieren bewegen zich over het bodem oppervlak of graven door het sediment en nemen zowel sediment als organismen (microben) en/of organisch materiaal op dat ze verteren (Lopez en Levinton, 2011). Het sediment wat ze consumeren bestaat gemiddeld voor meer dan 95% uit anorganisch materiaal en wordt weer uitgescheiden.…”
