|January 1, 1981

Summary

This summary is machine-generated.

Most yeasts can utilize amines as a nitrogen source, but not as a carbon and energy source. This study screened 461 yeast strains, finding broad nitrogen utilization but limited carbon assimilation from various amines.

Area of Science:

Microbiology
Yeast Physiology
Biochemistry

Background:

Yeasts are crucial microorganisms with diverse metabolic capabilities.
Amine compounds can serve as essential nutrient sources for microbial growth.
Understanding yeast assimilation pathways is vital for biotechnology and ecological studies.

Purpose of the Study:

To investigate the utilization of various amines by a large collection of yeast strains.
To determine if amines can be used as sole carbon and energy sources versus nitrogen sources.
To identify patterns in amine utilization across different yeast genera.

Main Methods:

Screening of 461 yeast strains from the Centraalbureau voor Schimmelcultures (CBS) collection.
Utilizing a miniaturized microtiter plate technique for high-throughput analysis.

Testing the ability of yeasts to utilize nine different primary and methylated amines.

Main Results:

No yeast strains utilized the tested amines (methylamine, dimethylamine, trimethylamine, tetramethylammonium chloride, choline, ethylamine, propylamine, butylamine, benzylamine) as a sole carbon and energy source.
86% of yeast strains successfully utilized at least one amine as a nitrogen source.
Utilization of ethylamine and higher homologues was more common than methylated amines.

Conclusions:

Yeasts predominantly utilize amines as a nitrogen source rather than a carbon and energy source.
Metabolic pathways for amine assimilation as a nitrogen source are widespread in yeasts.
The study highlights specificities in amine utilization, with longer-chain primary amines being more accessible than methylated amines.
