Recent observations of natural bacterial communities show high genetic diversity in organic
carbon uptake systems (microdiversity) and specificity in substrate species taken up. This …

Persistence of dissolved organic matter (DOM) in aquatic environments may in part be
explained by high diversity and low concentrations of carbon substrates. However, changes …

In the natural environment microorganisms are in constant mutual competition for the uptake
and consumption of nutrients. Particularly heteroptrophic microbes are exposed to a wide …

Bacteria have been usually assumed to play a major role in regeneration processes or in
conversion of refractory compounds into bacterial biomass. Recent studies have shown that …

Bacteria are major utilizers of dissolved organic matter in aquatic systems. In coastal areas
bacteria are supplied with a mixture of food sources, spanning from refractory terrestrial …

Studies on the effects of biodiversity on ecosystem functioning have generally revealed a
positive asymptotic relationship between biodiversity and single functions, suggesting …

Heterotrophic microbiallife in natural, nonpolluted aquatic ecosystems encounters one major
difficulty-limitation of available carbon sources. Dissolved organic compounds (DOC) are …

Heterotrophic marine bacteria utilize and recycle dissolved organic matter (DOM), impacting
biogeochemical cycles. It is currently unclear to what extent distinct DOM components can …

Aquatic environments are typically not homogenous, but characterized by changing
substrate concentration gradients and nutrient patches. This heterogeneity in substrate …

Microbial populations often display different degrees of heterogeneity in their substrate
assimilation, that is, anabolic heterogeneity. It has been shown that nutrient limitations are a …
