BioModTool : Biomass Modeling Tool

What is BioModTool ?

BioModTool is a Python library allowing easy generation of biomass objective functions for genome scale metabolic models from user data. BioModTool loads biomass composition data in the form of a structured Excel file previously completed by the user, normalizes, converts these data into model compatible unit (mmol.gDW^-1), and creates a structured biomass objective to update a metabolic model. BioModTool can be run as Python command-lines but it also comes with an interface allowing its use by non-modelers.

Installation

Use pip to install BioModTool from PyPI

 pip install BioModTool

In case you downloaded or cloned the source code from GitHub

 pip install <path-to-BioModTool-repo>

Application examples

BioModTool was applied to GEM of two bacteria species Escherichia coli (iML1515, Monk et al. 2017) and Alicyclobacillus acidocaldarius (CNA_Alicyclo, Beck, Hunt et Carlson 2018), and one microalga Chlamydomonas reinhardtii (iRC1080, Chang et al. 2011). These examples illustrate the three different contexts in which BioModTool can be used:

• Add a three level BOF in a model in which metabolic formula are available: iML1515
• Add a two level BOF in a model in which metabolic formula are not available: CNA_Alicyclo
• Add a one level BOF in a model in which metabolic formula are not available: iRC1080

All scripts and results of these three application examples are fully available on GitHub.
