About

Regina LaCost is a pioneering figure in industrial biotechnology, best known for her groundbreaking work in recombinant enzyme production. Her most influential contribution came with the 1991 paper "Commercial Levels of Chymosin Production by Aspergillus," which has garnered 167 citations and remains a cornerstone in the field. This research demonstrated the first successful large-scale production of chymosin—a key enzyme in cheese manufacturing—using genetically engineered Aspergillus fungi, effectively replacing traditional calf rennet and revolutionizing the dairy industry. LaCost’s work bridged fundamental molecular biology with practical commercial application, establishing a paradigm for cost-effective, scalable enzyme synthesis. Her achievements not only advanced food science but also set standards for fungal expression systems used in pharmaceuticals and industrial enzymes. With a career focused on optimizing microbial hosts for heterologous protein production, LaCost’s impact is measured in both citation counts and the global adoption of her methods. For students and researchers, her legacy exemplifies how targeted biotechnological innovation can transform an entire industry while addressing sustainability and scalability challenges.
