Measurement of ordinary heterotroph organism anoxic yield in anoxic-aerobic activated sludge systems
… is to investigate and quantify the ordinary heterotrophic organism (OHO) cell yield under anoxic conditions relative to its value under aerobic conditions for municipal sewage. In this regard, three primary objectives were identified: 1. Determine the ratio Y H,No: Y H,AE for real sewage in …

The exo-proteomic framework for nitrogen acquisition from proteinaceous organic matter in the model marine heterotroph Ruegeria pomeroyi DSS-3
… organic matter, and their rapid degradation by heterotrophic bacteria is an important process in releasing bioavailable nitrogen when other nitrogen containing substrates are deficient. Heterotrophs encode a wide variety of hydrolytic enzymes and nutrient transporters, which provide them with …

Freshwater Invertebrate Assimilation Nutrients from Detrital Biofilms Under Light and Phosphorus Manipulation
… how microbial biofilm constituents (i.e heterotroph and autotroph) contribute C and P to detritivore nutrition under raised light and nutrient regimes. I conducted a feeding study using detritivorous caddisflies (i.e. <em>Pycnopsyche </em>sp.) and conditioned leaf litter across a …

Lost in Starvation: How the interplay between physiology and ecology impacts bacterial persistence in a patchy landscape
Heterotrophic marine bacteria navigate a heterogeneous landscape of resources. Bacterial populations cycle through periods of feasting when attached to nutrient particles and periods of famine when foraging between hotspots; thus, bacterial physiological states and ecological processes are …

Quantification of Aggregate Formation in Prochlorococcus
… under some conditions. The presence of a heterotroph increased the robusticity of the culture and aggregate formations in all strains. The heat shock, similarly, increased aggregation in all strains by triggering the stress response. Moreover, the size of aggregates grew independently from …

Microbial production and consumption of marine dissolved organic matter
… responsible for secondary production by heterotrophic microbes in the sea. Despite the importance of DOM in marine food webs, details regarding how marine microbes cycle DOM are limited, and few definitive connections have been made between specific producers and consumers. Consumption is …

Dynamic aggregation and dispersal of Escherichia coli under cycles of feast and famine
… lab examining the dynamics of complex phototroph-heterotroph communities exhibiting fluorescence in multiple channels.

Novel mitochondrial metabolism in excavate protists
… within the mitochondria of a eukaryotic heterotroph.

Bacterioplankton dynamics in the Southern Benguela upwelling region
The role of heterotrophic bacteria in the carbon and nitrogen flux of the pelagic food web was investigated during laboratory and field-based studies of the temporal development of the planktonic community after upwelling. Bacterial community structure, activity and production were closely coupled …

Understanding The Molecular Mechanism Of Manganese Oxidation In Leptothrix Discophora Ss1
… information of Leptothrix as an obligate aerobic heterotroph, functional analysis of the draft genome revealed the potential for a diverse metabolism such as fermentation, anaerobic respiration with nitrate and arsenate, sulfur oxidation and carbon fixation. The information provided by the draft …

Characterization of an extremely thermophilic, anaerobic sulphur-dependent archaebacterium
… between 55 and 85°C. The organism is an obligate heterotroph with a requirement for peptone. In the presence of peptone, several amino acids, α-keto acids, glucose, lactose, casein, and starch stimulate growth. Sodium and sulphur are required for growth. Sodium can be replaced by lithium and …

Plastid Genome Evolution in the Parasitic Genera Cuscuta (Convolvulaceae) and Krameria (Krameriaceae)
… a handful of embryophyte lineages, however, a heterotrophic lifestyle has evolved and reliance on photosynthesis for resource acquisition is reduced or completely absent. In these plants, the selective pressure imposed by primary production is lifted and previously conserved features are able …

The ecology, life history, and phylogeny of the marine thecate heterotrophic dinoflagellates Protoperidinium and Diplopsalidaceae (Dinophyceae)
Marine thecate heterotrophic dinoflagellates likely play an important role in the consumption of primary productivity and in the trophic structure of the plankton, yet we know little about these species. This thesis expanded our understanding of the autecology and evolutionary history of the …
