Numerous microbial transformations (including their technological applications) followed, and during 1970-1990 these yeast (or microorganism or enzymatic)-mediated bioconversions, biotransformations, or biodegradations were hailed as an ultimate tool for synthetic transformations. They seemed to be suited [8-16] to displace traditional organic chemistry. This opinion was revised, and an initial enthusiasm was
