Auxotrophy - Wikipedia
网页Auxotrophy (Ancient Greek: αὐξάνω "to increase"; τροφή "nourishment") is the inability of an organism to synthesize a particular organic compound required for its growth (as defined by IUPAC). An auxotroph is an organism that displays this characteristic; auxotrophic is the corresponding adjective.
The social network of microorganisms — how auxotrophies
网页2018年3月29日 · Most microorganisms are auxotrophs, thus relying on external nutrients for growth, including the exchange of amino acids and vitamins. Currently, we lack a deeper understanding of auxotrophies in...
Amino acid auxotrophies in human gut bacteria are linked to …
网页2023年10月27日 · Amino acid auxotrophies are prevalent among bacteria. They can govern ecological dynamics in microbial communities and indicate metabolic cross-feeding interactions among coexisting genotypes.
6.3: Auxotrophs and selective media - Biology LibreTexts
网页Auxotrophs are microorganisms that are unable to synthesize an essential nutrient because of a gene mutation. Many laboratory strains carry multiple mutations that interfere with the synthesis of essential nutrients.
Auxotrophy - an overview | ScienceDirect Topics
网页Auxotrophs are primarily isolated by plating the mutagenized population on a complete medium that has all the nutrients needed for growth. The clones are then replica-plated to minimal medium lacking some specific nutrients, and auxotrophs that fail to grow on minimal media are identified.
Metabolic adaptation to vitamin auxotrophy by leaf-associated …
网页2022年8月20日 · In co-culture experiments, we demonstrated vitamin supply to auxotrophs, and found that auxotrophic strains maintained higher species richness than prototrophs upon external supplementation with...
Auxotrophy - an overview | ScienceDirect Topics
网页Auxotrophs are commonly used in filamentous fungi transformation, which requires a gene, or the selectable marker, that restores prototrophy. However, the bottleneck of using auxotrophy as a selectable marker is that a starting mutant strain is needed.
Prototrophs vs. Auxotrophs - Video Tutorials & Practice Problems
网页His- auxotrophs are the mutant bacterial cells which require growth factors to grow. His- auxotrophs cannot grow without the amino acid histidine. All of the above answers are correct.
