Evaluating most probable number method to count and isolate viable methylotrophs.

Area of Science:

• Microbiology
• Analytical Chemistry

Background:

• The Most Probable Number (MPN) method is a standard technique for estimating microbial populations.
• Selecting appropriate receptacles is crucial for the accuracy and efficiency of MPN counts.
• Methylotrophs are microorganisms capable of utilizing one-carbon compounds, important in various environmental and industrial processes.

Purpose of the Study:

• To evaluate the reliability and cost-effectiveness of nine different receptacles for MPN analysis.
• To identify the optimal vessel for accurate MPN enumeration.
• To assess the impact of the chosen receptacle on the isolation of viable Methylotrophs.

Main Methods:

• A comparative study was conducted using nine distinct types of receptacles.
• The Most Probable Number (MPN) method was applied to each receptacle type.
• Microbial counts and isolation efficiency were assessed for viable Methylotrophs.

Main Results:

• Significant variations in MPN count reliability and economy were observed across the tested receptacles.
• The 96-well PCR plate demonstrated superior performance compared to other vessels.
• Utilizing the 96-well PCR plate facilitated the successful isolation of viable Methylotrophs.

Conclusions:

• The 96-well PCR plate is the most reliable and economical choice for conducting MPN counts.
• This vessel type enhances the isolation efficiency of viable Methylotrophs in microbial analyses.
• The findings provide practical guidance for optimizing MPN-based microbial enumeration studies.
