“…Limonene (4-isopropenyl-1-methylcyclehexane), a monocyclic monoterpene, is a low priced monoterpene and in most cases the major compound in essential oils of citrus fruits (De Conti, Rodrigues, & Moran, 2001;Onken & Berger, 1999;van der Werf, de Bont, & Leak, 1997). Pinenes are bicycle monoterpenes of low price and commonly used as substrates for biotransformation (De Conti et al, 2001).…”

Verbenol is a bicyclicbicycle secondary allylic alcohol, with pronounced camphor and mint flavor notes, mainly used as food flavoring. This compound is also used to control harmful insects, and hence has potential for using in agriculture, and is an intermediate in the synthesis of valuable perfume and medicinal substances. This work is focused on the microbial oxidation of (-)-α-pinene to verbenol production. To carry out the present study, 405 microorganisms were tested for their ability to bioconvert the substrate. From the isolated microorganisms, 193 were selected in the pre-screening using mineral medium for limonene degradation. At the screening step, 31 strains were able to convert (-)-α-pinene in verbenol. The highest concentration in verbenol from (-)-α-pinene was about 125.6 mg/L for yeast isolated from orange juice industrial residue.

Abstract:Since the mid-twentieth century, by economic and environmental factors, many researchers and some industries are investing in the development of syntheses and technologies that are environmentally friendly, producing less toxic waste and saving energy. Furthermore, the use of renewable raw materials, biomass and the development of asymmetric methods that provide products with high yields and selectivities becomes a major challenge for researchers in various fields that employ the catalytic process. This paper describes the importance of catalysis in organic synthesis of complex molecules, especially for the pharmaceutical and fine chemicals industries. Indeed, the industrial revolution caused by catalysis in different sectors such as petrochemicals, plastics, paper, among others, also became the subject of interest of this review.Keywords: Homogeneous catalysis; heterogeneous catalysis; biocatalysis; organocatalysis. ResumoDesde meados do século XX, por razões econômicas e ambientais, diversos pesquisadores e algumas indústrias investem no desenvolvimento de tecnologias sintéticas que sejam ambientalmente favoráveis, gerando menos resíduos tóxicos e com economia de energia. Além disso, os processos catalíticos e biocatalíticos associados ao uso de biomassas renováveis são de fundamental importância para a produção de matérias-primas quirais e aquirais com altos rendimentos e elevadas seletividades. Esse conjunto de paradigmas é um dos grandes desafios da atualidade para os pesquisadores nos diversos ramos da síntese orgânica.Este trabalho descreve a importância da catálise e da biocatálise na síntese orgânica de moléculas complexas, destacando-se os setores de química fina e fármacos. Além disso, a utilização crescente dos diversos processos catalíticos em diferentes setores industriais, tais como petroquímico, de papel e celulose, plásticos, e muitos outros também são assuntos de interesse desse trabalho de revisão.Palavras-chave: Catálise homogênea; catálise heterogênea; biocatálise; organocatálise.
