Current public health messages represent the ‘tip of the iceberg’. We describe three public health microbiome curriculum modules on breastfeeding, antibiotics and diet that examine how upstream factors affect the microbiome and influence health across the life course.

High-traffic areas, such as mass transportation environments, can have a significant impact on infection transmission, and chemical disinfection may favour the selection of drug-resistant microbes. Probiotic-based approaches have the potential to be a novel and ecologically sustainable option for controlling bioburden and preventing infections.

We describe a methanol-free protein expression platform for Komagataella phaffii. This platform uses a HSP70 promoter induced by magnetic or non-magnetic heating.
