“…An optimal series of Hypersol-Macronet™ sorbent resins for industrial application was developed by Purolite International Ltd. However, crosslinked polystyrene resins have turned out to be the most eYcient adsorbents for recovering Xavour compounds from aqueous solution [12,13]. Valderrama et al [14] described the sorption of six polycyclic hydrocarbons from an aqueous solution on the Macronet polymeric sorbent MN-200.…”

During the biotransformation of castor oil into gamma-decalactone, R. aurantiaca produced both the lactone form and its precursor (4-hydroxydecanoic acid). After six days of culture, a maximum yield of gamma-decalactone of 6.5 g/l was obtained. The parameters of gamma-decalactone adsorption on three Macronet resins (MN-202, MN-102 and MN-100) were investigated in water. Adsorption isotherms of gamma-decalactone for the three Macronet resins were linear. The trapping of gamma-decalactone produced by R. aurantiaca on these resins was then carried out. gamma-Decalactone was effectively retained by all the studied Macronet resins. The resin MN-202 trapped gamma-decalactone more efficiently than MN-102 and MN-100. The percentages of gamma-decalactone adsorbed on the resins MN-202, MN-102 and MN-100 were, respectively, 85, 75 and 81%, whereas around 70% of the adsorbed gamma-decalactone was then desorbed. We propose an industrial process that uses Macronet resins to extract gamma-decalactone from culture broth of R. aurantiaca.

Supplementation of the key metabolite, alpha-(Z)-acaridiol, to stirred-tank cultured Pleurotus ostreatus was used to demonstrate that integrated in situ product recovery resulted in high conversion rates and quantitative separation of the target product perillene from the nutrient medium. The conversion of beta-myrcene by P. ostreatus was scaled-up from shake-flasks into a controlled, stirred tank bioreactor equipped with gas stripping and adsorption on a polystyrene fixed bed. The formation of the attractive flavour compound perillene was measured daily using standard controlled capillary gas chromatography. The formation of alpha-(Z)-acaridiol was the metabolic bottleneck of the conversion of beta-myrcene to perillene. Efficient in situ recovery of the volatile product enabled quantitative separation of the pure flavour compound. Appropriated bioprocessing, i.e. in situ separation of product, steadily shifted the metabolic equilibria and thus accomplished high conversion rate and pure product.

“…The basic principle of terpene biotransformation, however, is the feeding of a nonpolar terpene hydrocarbon which is to be converted into more polar products after the incorporation of at least one oxygen atom. In principle, this contradiction can be solved using a two step adsorption process and selective adsorbents [132]. In the case of a very volatile flavor product, gas stripping is the most favorable method for in situ recovery.…”

The usage of essential oils as such or of volatile fractions thereof is widespread in the flavor and fragrance industry to aromatize perfumery and cosmetic products, foodstuffs, and many household and pharmaceutical products. The increased market share of convenience food together with consumers' request for constant high quality and natural products have established a lasting increase in the demand for natural flavorings that cannot be satisfied by the traditional plant materials. This review summarizes selected work on terpene bioconversion / transformation and focuses on recently published papers dealing with novel strains and products, high product yields, intriguing genetic engineering approaches, and integrated bioprocesses. The future perspectives of an industrial realization of a biotechnological production of terpene-derived natural flavors are critically evaluated.
