Industrial biotechnology (IB) has the potential to create new markets while protecting the environment. With this in mind, the EU-funded BIOINDUSTRY 4.0 project will pave the way for IB to become a major manufacturing technology. Supporting the digitalisation of IB, the project will create new services delivered by European research infrastructure. These will address several challenges, focusing on the acceleration of bioprocess development pipelines. ...

Scorpionism is a serious public health problem in tropical areas, especially in Africa, southern India, the Middle East, and Latin America. There are about 12 species of scorpions that are dangerous to humans and all belong to the Buthidae family. In particular, venom on scorpion Androctonus australis hector is particularly toxic to humans. Serotherapy uses antibodies or fragments of antibodies to target the neurotoxins of the scorpion venom. Nanobodies, camelid-derived antibodies, are more ...
