Rapid microbiological assay for chlorhydroxyquinoline that uses a cryogenically stored inoculum.

Area of Science:

• Microbiology
• Analytical Chemistry

Background:

• Chlorhydroxyquinoline is an antimicrobial agent requiring accurate quantification.
• Existing assays may be time-consuming or lack efficiency.

Purpose of the Study:

• To develop and validate a rapid microbiological assay for chlorhydroxyquinoline.
• To evaluate the benefits of using cryogenically stored inocula.

Main Methods:

• A turbidimetric assay procedure was employed.
• Streptococcus faecalis was utilized as the test microorganism.
• Comparison between daily and cryogenically stored inocula was performed.

Main Results:

• The assay provides results within 5 hours.
• Cryogenically stored inocula demonstrated advantages over daily prepared inocula.
• The method is suitable for rapid chlorhydroxyquinoline determination.

Conclusions:

• A rapid and efficient turbidimetric assay for chlorhydroxyquinoline is established.
• The use of cryogenically stored inocula enhances assay performance and speed.
• This method offers a practical approach for microbiological analysis.
