| Open AccessMicrobial interactions shape cheese flavour formation
Cheese fermentation and flavour formation are the result of complex biochemical reactions driven by the activity of multiple microorganisms. Here, the authors identify microbial interactions as a mechanism underlying flavour formation in Cheddar cheese.

| Open AccessRoles of adenine methylation in the physiology of Lacticaseibacillus paracasei
The bacterium Lacticaseibacillus paracasei is used in the food industry and as a probiotic. Here, the authors use multi-omics and high-throughput chromosome conformation capture analyses to investigate the roles of a type of DNA methylation (N6-methyladenine modification) in this organism.

| Open AccessMacroevolutionary diversity of traits and genomes in the model yeast genus Saccharomyces
Here, the authors describe the geographies, hosts, substrates, and phylogenetic relationships for 1,794 Saccharomyces strains. They provide insight into the genetic and phenotypic diversity in the genus, not seen through prior work focused on the model species Saccharomyces cerevisiae.

| Open AccessColonization of the human gut by bovine bacteria present in Parmesan cheese
Some microorganisms may be transferred across the food production chain and, potentially, colonize the human gut. Here, Milani et al. provide strain-level evidence supporting that dairy cattle-associated bacteria can be transferred to the human gut via consumption of Parmesan cheese.

| Open AccessEnterohemorrhagic Escherichia coli senses low biotin status in the large intestine for colonization and infection
Enterohaemorrhagic Escherichia coli(EHEC) is an important foodborne pathogen that colonizes the large intestine. Here, the authors identify a signalling pathway that controls EHEC adherence to host cells in response to variations in biotin levels, ensuring selective colonization of the large intestine.

| Open AccessMultiple recent horizontal transfers of a large genomic region in cheese making fungi
Horizontal gene transfers are known to play an important role in prokaryote evolution but their impact and prevalence in eukaryotes is less clear. Here, the authors sequence the genomes of cheese making fungi P. roqueforti and P. camemberti, and provide evidence for recent horizontal transfers of a large genomic region.
