The approach applies supervised machine learning to establish 86 metabolic and ecological functional classes from widely available genome annotations. Validation on independent datasets shows robust performance across complete, fragmented, and incomplete genomes with >70% completeness for most functions. The tool generalizes to metagenomic and single-cell datasets and is demonstrated via applications to biogas microbiome predictions and a refined acetoclastic methanogenesis case.","Bizzotto et al. Environmental Microbiome (2024) 19:58 Environmental Microbiome  \n[https://doi.org/10.1186/s40793-024-00600-6](https://doi.org/10.1186/s40793-024-00600-6)  \nRESEARCH Open Access  \nMICROPHERRET: MICRObial PHEnotypic tRait  ClassifieR using Machine lEarning Techniques  \nEdoardo Bizzotto 1†, Sofia Fraulini 1†, Guido Zampieri 1*, Esteban Orellana 1, Laura Treu 1 and Stefano Campanaro 1*  \nAbstract  \nBackground In recent years, there has been a rapid increase in the number of microbial genomes reconstructed through shotgun sequencing, and obtained by newly developed approaches including metagenomic binning and single-cell sequencing. However, our ability to functionally characterize these genomes by experimental assays is orders of magnitude less efficient. Consequently, there is a pressing need for the development of swift and automated strategies for the functional classification of microbial genomes.  \nResults The present work leverages a suite of supervised machine learning algorithms to establish a range of 86 metabolic and other ecological functions, such as methanotrophy and plastic degradation, starting from widely obtainable microbial genome annotations. Tests performed on independent datasets demonstrated robust performance across complete, fragmented, and incomplete genomes above a 70% completeness level for most of the considered functions. Application of the algorithms to the Biogas Microbiome database yielded predictions broadly consistent with current biological knowledge and correctly detecting functionally-related nuances of archaeal genomes. Finally, a case study focused on acetoclastic methanogenesis demonstrated how the developed machine learning models can be refined or expanded with models describing novel functions of interest.  \nConclusions The resulting tool, MICROPHERRET, incorporates a total of 86 models, one for each tested functional class, and can be applied to high-quality microbial genomes as well as to low-quality genomes derived from metagenomics and single-cell sequencing. MICROPHERRET can thus aid in understanding the functional role of newly generated genomes within their micro-ecological context.  \nKeywords Functional classification, Machine learning, Microbial genome, Metagenome, Methanogenesis  \n†Edoardo Bizzotto and Sofia Fraulini contributed equally to this work.  \n*Correspondence:  \nGuido Zampieri [guido.zampieri@unipd.it](guido.zampieri@unipd.it)[ ](guido.zampieri@unipd.it)Stefano Campanaro [stefano.campanaro@unipd.it](stefano.campanaro@unipd.it)  \n1Department of Biology, University of Padova, Padova 35131, Italy  \nBackground  \nGenome-centric metagenomics allows the reconstruction of draft genomes of single microorganisms called metagenome-assembled genomes (MAGs) [1]. Analysis of diverse MAGs from both phylogenetic and functional perspectives enables a comprehensive exploration of the taxonomic composition and functional processes within the sampled microbial community [2, 3]. From an ecological standpoint, metagenomics studies offer invaluable insights into ecosystem functions and responses to environmental dynamics [4].
