Biotechnology Letters Aims and scope Submit manuscript

Summary

A Technicon AutoAnalyzer has been adapted to analyse lysine of fermentation broths from lysine-producer mutants, with a photometric method with ninhydrin. Linearity and accuracy have been tested, with errors lower than 5.5%. The great advantadge is its speed, analysing one sample every 5 minutes, automatically.
