|January 1, 1988
Summary
A new Rhizobium meliloti strain (GY654) selectively quantifies tobramycin and 6"-O-carbamoyltobramycin. This antibiotic-resistant strain is ideal for measuring these compounds in complex mixtures like fermentation broths.
Area of Science:
- Microbiology
- Biotechnology
- Analytical Chemistry
Background:
- Aminoglycoside antibiotics like tobramycin are crucial therapeutics.
- Accurate quantification of antibiotics in fermentation broths is essential for process optimization.
- Existing methods may struggle with complex mixtures containing related compounds.
Purpose of the Study:
- To develop a novel microbial strain for selective antibiotic detection.
- To enable rapid and accurate quantification of tobramycin and its derivative.
- To facilitate antibiotic analysis in challenging matrices.
Main Methods:
- Construction of a mutant Rhizobium meliloti 41 strain (GY654) with specific antibiotic resistance profiles.
- Utilizing strain GY654 for selective measurement of target antibiotics.
- Application in analyzing antibiotic mixtures from Streptomyces tenebrarius fermentation and synthetic solutions.
Main Results:
- Strain GY654 demonstrated resistance to apramycin and kanamycin, while remaining sensitive to tobramycin.
- The strain selectively measured tobramycin and 6"-O-carbamoyltobramycin.
- Successful application in quantifying these antibiotics in fermentation broths and solvent mixtures.
Conclusions:
- Strain GY654 offers a robust and selective method for tobramycin and 6"-O-carbamoyltobramycin quantification.
- This approach simplifies antibiotic analysis in complex biological and chemical samples.
- The developed strain has significant potential for quality control and process monitoring in antibiotic production.
