Food is essential to provide energy for human cellular metabolism, and is usually made from plants or animals. Beside plants and animals, other important food sources are made by microorganisms, typically products of fermentation (e.g bread, wine, beer, soy sauce, etc). Nowadays, because of the increasing environmental pollution, climate change and population growth, is becoming challenging to keep the food supply safe, nutritious and sustainable. Importantly, the development of the synthetic biology field enable the engineering of cells that can be used in food manufacturing.
Microplastic pollution has sparked interest from researchers, public, industries, and regulators owing to reports of extensive presence of microplastics in the environment, household dust, drinking water, and food, which indicates chronic exposure to organisms within ecosystems and in human living spaces. Although exposure to microplastics is evident, negative effects from microplastics appear to be minimal in most studies on biota, and no risk assessments have been completed for microplastics on human health.
