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 ...
In the biopharmaceutical industry, nanobodies show promising properties for its application in serotherapy for serums targeting the most toxic components of scorpion venom. Nevertheless, the limited number of scientific publications on the production of nanobodies for antivenom productions poses a challenge. The reported yield is low (< 4 mg/L), biomass production is not reported, and the production in high cell density cultures have not been studied. Production conditions (temperature of ...
