Application Notes
Gentamicin Sulfate is an aminoglycoside antibiotic that is effective against many Gram-negative bacteria, e.g., Brucella, Escherichia, Enterobacter, Francisella, Yersinia, etc., and some strains of staphylococci. It inhibits the initiation, elongation and termination of protein synthesis by binding to the 30S subunit and sometimes the 50S subunit of the bacterial ribosome.2 Gentamicin is suitable for plant tissue culture use as it is stable for autoclaving; however, it has been reported that gentamicin inhibits growth of tobacco, sapiglossis, romaine lettuce and artichoke at high concentration ranging from 50 to 100 µg/mL.3, 4
Minimum inhibitory concentration (MIC) of gentamicin has been reported for many bacteria. MIC for Escherichia coli is 0.05 µg/mL, Bacteroides spp. is greater than 128 µg/mL, and Clostridium spp. is 112 µg/mL. 5
PhytoTechnology Laboratories® also carries gentamicin sulfate solution 100 mg/mL, Product No. G3410, and gentamicin sulfate powder, Product No. G570.
Please note: It is the sole responsibility of the purchaser to determine the appropriateness of this product for the specific plants that are being cultured and applications that are being used.
