Moreover, the addition of calcium not only supports the structural integrity of bones and teeth but also contributes to muscle contraction, neurotransmission, and various enzymatic activities. The synergistic effects of d,l-α-ketoisoleucine and calcium underscore their importance in promoting overall health and well-being.
Penicillin, a pioneer among antibiotics, once had a production process that caused significant environmental pollution. In recent years, with the application of eco-friendly pharma intermediates, penicillin production has become cleaner and more efficient. For instance, using biocatalysis instead of chemical catalysis not only increases penicillin yield but also significantly reduces wastewater and gas emissions, achieving green production processes. Additionally, optimizing fermentation techniques has improved the biosynthesis efficiency of penicillin, reduced chemical synthesis steps, and lowered energy and resource consumption.
