A key control knob for microbiome metabolism

Researchers are uncovering the complex mechanisms by which human gut bacteria accomplish a variety of functions, from transforming compounds derived from food into nutrition for the host to producing molecules that impact human behavior and performance. The Venturelli Lab has now overturned prior knowledge about how polysaccharide utilization loci (PULs) mediate the fitness and community-level …

Computational design of microbial communities

Microbial communities are everywhere in the environment. The interactions among these complex networks of organisms shape the overall community function and metabolism, sometimes in unexpected ways. In a paper published May 31 in Nature Communications, a team led by University of Wisconsin–Madison assistant professor of biochemistry Ophelia Venturelli describes a generalizable, model-driven framework to predict …

Venturelli Lab develops computational model to predict butyrate production in the human gut microbiome

Researchers have developed the capability to predict and design the metabolic activities of microbial communities, which has broad implications for human health, agriculture and bioprocessing. In a paper released May 31st in Nature Communications [link], Biochemistry Assistant Professor Ophelia Venturelli and Ryan Clark, formerly a postdoc in the Venturelli lab and now of Nimble Therapeutics, …

Venturelli Lab receives R21 to research antibiotic resistant genes

Biochemistry Assistant Professor Ophelia Venturelli has been awarded an Exploratory/ Developmental Research Grant (R21) by the National Institutes of Health (NIH). The award is in support of the development of new methods to uncover associations between antibiotic resistance genes and microbial hosts in the human gut microbiome. The rise and spread of bacteria that are …

NIH funds R01 grant to study a model-guided design of next-generation bacterial therapeutics to treat cardiovascular disease

Ophelia Venturelli (Biochemistry) in collaboration with Philip Romero (Biochemistry) and Federico Rey (Bacteriology) were awarded an R01 grant through the National Institute of Biomedical Imaging and Bioengineering. The award will provide a total of $2.7M over four years. The team will develop computational modeling and optimization techniques to design next-generation bacterial therapeutics that sense major …
