Abstract: As trend to use natural products in cosmetics and cosmeceuticals grows, the need to produce new cheap, natural, safe and effective bioactive compounds from natural sources increases too [1], [2]. The aim of this study is to make a crude extract with antioxidant and/or enzymatic properties using solid-state fermentation (SSF) of wheat bran with two fungal strains and prepare a cosmetic product for desired purpose. Two Pleurotus spp. edible fungi – P. ostreatus and P. eryngii, are used in this research. Those fungi are considered as safe for medicinal properties and are attractive sources of natural antioxidant, antimicrobial, anti-inflammatory compounds and oxidative enzymes which could protect respectively from cell aging and oxidative damage of free radicals, microorganism growth in cosmetic products and they may improve skin tone and texture, lighten skin [3]. It is known that solid-state wheat fermentation can enhance the extraction yield, total phenolic, flavonoid and antioxidant activity [4]. This study first examines optimal conditions for the wheat bran fermentation. Two different speeds (6 rpd and 12 rpd) for the rotating drum bioreactor and three different wheat bran moisture levels (67%, 75%, and 80%) are set (6 jars with P. eryngii homogenized inoculum and 6 jars with P. ostreatus). Crude extract will be prepared by hot water extraction. Spectrophotometric methods such as determination of total phenolic compounds using Folin-Ciocalteu reagent, the total content of flavonoids, antioxidant activity measurement by radical scavenging activity (DPPH), laccase and peroxidases activity measurement by monitoring ABTS enzymatic oxidation will be performed. After determining the optimal conditions, they will be used for the obtainment of crude extracts and the formulation of a skin cream considering extract physicochemical properties.[...]
