[The mixotrophy of pathogenic bacteria].

Zhurnal mikrobiologii, epidemiologii i immunobiologii, 1995
This work deals with materials on the utilization of carbon dioxide and hydrogen from gas-air mixture by Yersinia pseudotuberculosis and Listeria monocytogenes in the process of their cultivation in Hirsch's mineral medium. As follows from the data presented in these materials, the above-mentioned bacterial species are heterotrophic when the infectious

THE IMPORTANCE OF OSMO-MIXOTROPHY IN THE NUTRITION OF THE DIATOM THALASSIOSIRA OCEANICA UNDER IRON LIMITATION

, 2017
This thesis addresses the potential for osmo-mixotrophy within the diatom species Thalassiosira oceanica under iron-limited and iron-replete conditions. Urea can provide both carbon and nitrogen to fulfill the cellular requirements of diatoms. Laboratory

Mixotrophy: the missing link in consumer-resource-based ecologies [PDF]

, 2015
The classical separate treatments of competi- tion and predation and difficulties in providing a sensible theoretical basis for mutualism attest to the inability of traditional models to provide a synthesising framework for trophic interactions, a ...

Synechococcus sp. strain PCC 7002 transcriptome: acclimation to temperature, salinity, oxidative stress and mixotrophic growth conditions

Frontiers in Microbiology, 2012
Synechococcus sp. strain PCC 7002 is a unicellular, euryhaline cyanobacterium. It is a model organism for studies of cyanobacterial metabolism and has great potential for biotechnological applications.

Mixotrophy in nanoflagellates across environmental gradients in the ocean [PDF]

Proceedings of the National Academy of Sciences, 2019
Significance Many single-celled photosynthesizers can also consume other organisms, a trophic strategy known as mixotrophy. It has become clear that mixotrophs are widespread in the ocean, but we know less about the environmental conditions under which they thrive, and whether their abundance is driven by competition with more ...

Using an acidic vesicle tracer to identify potential bacterivores in coastal waters of the subtropical Western Pacific Ocean

Frontiers in Marine Science
Bacterivores play a key role in transferring energy through microbial food webs and are broadly classified as heterotrophic or mixotrophic based on the presence of inherent chloroplasts.

Strombidium rassoulzadegani: A Model Species for Chloroplast Retention in Oligotrich Ciliates

Frontiers in Marine Science, 2018
Strombidium rassoulzadegani is a planktonic ciliate that retains chloroplasts from its food and uses them to obtain a nutritional supplement from photosynthesis.

High Grazing Rates on Cryptophyte Algae in Chesapeake Bay

Frontiers in Marine Science, 2018
Cryptophyte algae are globally distributed photosynthetic flagellates found in freshwater, estuarine, and neritic ecosystems. While cryptophytes can be highly abundant and are consumed by a wide variety of protistan predators, few studies have sought to ...
