The aim of this study was the modification of lovastatin by microbes to improve its potential. Actinobacteria exhibit staggering diversity in terms of their biosynthetic capability for specialized metabolites which has been traced back to the presence of specialized gene clusters. The objective of the study is to exploit the potential of Actinobacteria strain(s), which can biotransform lovastatin to simvastatin, which might be a more potent therapeutic agent than lovastatin. We have screened 40 Actinobacteria strains and assessed their biotransformation potential primarily through thin layer chromatography (TLC) analysis, followed by high performance thin layer chromatography and high performance liquid chromatography analysis. One strain C7 (CTL S12) has been identified as a potential Actinobacteria that favored the simvastatin biotransformation. The morphological and biochemical analysis together with 16S rRNA sequencing coupled with phylogenetic analysis confirmed the ideal strain (C7) as Streptomyces carpaticus. Successively, the purified simvastatin from S. carpaticus was characterized by liquid chromatography–mass spectrometry (LC–MS), infrared spectrometry, nuclear magnetic resonance, and HMG‐CoA assay. In the LC–MS analysis, a peak at 419.24 m/z confirmed the elemental composition of simvastatin (C25H39O5). In HMG‐CoA assay, the IC50 of simvastatin was 50 μg/ml, and the inhibitory potential was 1.36 times higher compared to that of lovastatin. Thus, the biotransformation of simvastatin from lovastatin by S. carpaticus is reported for the first time.
