INTRODUCTION

 

What is IPMP 2013?

 

            IPMP 2013 is a new generation predictive microbiology tool.  It is designed to analyze experimental data commonly encountered in predictive microbiology and for the development of predictive models.

 

Why IPMP 2013?

 

            Modern predictive microbiology has significantly evolved since the 1980’s.  While progress has been achieved in predictive microbiology research, there is, however, no comprehensive data analysis and model development tool.  Many researchers use commercial general-purpose statistical analysis and mathematical tools, such as SAS®, Matlab®, Mathematica®, S-Plus®, or SPSS®, while others use open-source statistical analysis tools, such as R, for data analysis and model development.  Unfortunately most of these general-purpose tools require program-specific programming.  For someone lacking programming knowledge, it can be difficult to use these tools effectively.  Additionally, commercial statistical packages and math tools are expensive.  IPMP 2013 is developed by USDA-ARS to meet the needs of the predictive microbiology scientific community.  Offered as a free tool, IPMP is a simple-to-use data analysis platform for developing predictive models.  With IPMP 2013, anyone, with a basic knowledge of predictive microbiology, can use it to analyze kinetic data and develop predictive models for microorganisms.

 

What can IPMP 2013 do?

 

            IPMP 2013 is a data analysis tool developed to analyze the kinetic data of microbial growth and inactivation frequently found in predictive microbiology.  It is specifically designed to develop primary and secondary models, and contains user-friendly interfaces that allow the user to enter and analyze kinetic data by selecting certain mathematical models.

 

What is required to use IPMP 2013?

 

            All the statistical analysis and model development are handled seamlessly behind the scenes.  No programming knowledge is needed.  The user only needs to enter the data and click a few buttons on the screen to complete any data analysis.  The only requirement is that the user have a basic knowledge of predictive microbiology to allow for the selection of suitable models for data analysis.

 

What models are included in IPMP 2013?

 

            IPMP 2013 was developed to analyze primary and secondary models.  More complex models may be included in the future.  The primary models include common growth and inactivation models.  They can be used to analyze full growth curves (containing all three phases), incomplete growth curves, or inactivation/survival curves.  The secondary models are used to evaluate the effect of temperature on growth rate.
