Abstract

The main objective of this article was to present the possibilities of using the enzymatic system of microorganisms and insects to transform small molecules, such as monoterpenes. The most important advantage of this type of reaction is the possibility of obtaining derivatives that are not possible to obtain with standard methods of organic synthesis or are very expensive to obtain. The interest of industrial centers focuses mainly on obtaining particles of high optical purity, which have the desired biological properties. The cost of obtaining such a compound and the elimination of toxic or undesirable chemical waste is important. Enzymatic reactions based on enzymes alone or whole microorganisms enable obtaining products with a specific structure and purity in accordance with the rules of Green Chemistry.

Highlights

  • The study of the properties and composition of plant secondary metabolites is of interest to many scientists

  • In this work we focused on the biotransformation of several popular one-ring monoterpenes

  • For (−)-menthol biotransformation 12 isolates from Rhizoctonia solani, a plant pathogen commonly found in soil, were used

Summary

Introduction

The study of the properties and composition of plant secondary metabolites is of interest to many scientists. Monoterpenes as isoprene dimers are the simplest terpenes [2] These compounds are the main components of essential oils found in plants of different climate zones. We know that essential oils are responsible for the fragrance of the raw material and they can attract pollinating insects [6] Scientists have confirmed their physiological roles include chemical defenses against abiotic and biotic stresses [7,8], e.g., it protects against bacterial or fungal infection, insect or plant-eating animals. Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), is a polyphagic pest, widespread throughout South and East Asia, Africa and Oceania [15] It feeds on over 389 species of plants [16], including legumes, cotton, cabbage, cauliflower, castor, peanut, tubers and oilseeds [17]. For the comparison of the type of products, in addition to microorganisms, the larvae of Spodoptera litura, known for their ability to biotransform terpenes, are presented here [24]
