1. A functional food: a traditional Tarhana fermentation
Abstract White wheat flour, concentrated full fat yoghurt, tomato paste, onion, red and green paprika, and mint and salt are used in the preparation of Tarhana. During the 7-day Tarhana fermentation period, the acidity increased from 1.10% to 3.25%, the pH decreased from 5.22 to 4.13, and the moisture decreased from 70.12% to 26.15%. The chemical composition

2. COMPOSTING TIME REDUCTION OF AGRO-INDUSTRIAL WASTES
ABSTRACT The agro-industrialization of animal products has led to a significant waste generation, which has been stabilized by composting process in specialized plants. Waste stabilization time on composting depends on the handling used. 12 treatments were performed, three frequency turnings combined with two environmental conditions (with and without covera

3. Effectiveness of convective drying to conserve indigenous yeasts with high volatile profile isolated from algerian fermented raw bovine milk (Rayeb)
Abstract Yeasts Candida tropicalis, Yarrowia lipolytica, Wickerhamomyces anomalus, Issatchenkia orientalis, Kluyveromyces marxianus, Saprochaete suaveolens and Trichosporon coremiiforme were isolated and identified by physiological, biochemical tests with API 20C AUX system and molecular methods by restriction fragment analysis of PCR-amplified 28S-rRNA from

4. NITROGEN SOURCES ON TPOMW VALORIZATION THROUGH SOLID STATE FERMENTATION PERFORMED BY Yarrowia lipolytica
Abstract This manuscript reports the valorization of two-phase olive mill waste (TPOMW) as raw material and carbon source for solid state fermentation using Yarrowia lipolytica as biocatalyst. Due to its chemical characteristics, a combination of different raw materials (TPOMW and wheat bran, WB) was evaluated and two distinct nitrogen sources were applied a

5. Enhanced production of erythritol and mannitol by Yarrowia lipolytica in media containing surfactants
Abstract Various chemical compounds, including surfactants, when introduced to culture media may increase the permeability of cellular membranes and thereby affect the quantity of metabolites excreted by cells. The aim of the present study was to evaluate the impact of detergents including Triton X-100, Span 20 and Tween 80 on erythritol production from glyc

6. Bioconversion of R-(+)-limonene to perillic acid by the yeast Yarrowia lipolytica
Perillyl derivatives are increasingly important due to their flavouring and antimicrobial properties as well as their potential as anticancer agents. These terpenoid species, which are present in limited amounts in plants, may be obtained via bioconversion of selected monoterpene hydrocarbons. In this study, seventeen yeast strains were screened for their ab

7. Use of Plackett-Burman design for rapid screening of nitrogen and carbon sources for the production of lipase in solid state fermentation by Yarrowia lipolytica from mustard oil cake (Brassica napus)
Mustard oil cake (Brassica napus), the residue obtained after extraction of mustard oil from mustard oil seeds, was investigated for the production of lipase under solid state fermentation (SSF) using the marine yeast Yarrowia lipolytica NCIM 3589. Process parameters such as incubation time, biomass concentration, initial moisture content, carbon source conc

8. Factors influencing crude oil biodegradation by Yarrowia lipolytica
Yarrowia lipolytica is unique strictly aerobic yeast with the ability to efficiently degrade hydrophobic substrates such as n-alkenes, fatty acids, glycerol and oils. In the present work, a 2(4) full factorial design was used to investigate the influence of the independent variables of temperature, agitation, initial cell concentration and initial petroleum

9. Renewable resources for biosurfactant production by yarrowia lipolytica
In this work, the production of a biosurfactant synthesized by Yarrowia lipolytica using different renewable resources as carbon source was investigated. Crude glycerol, a biodiesel co-product, and clarified cashew apple juice (CCAJ), an agroindustrial residue, were applied as feedstocks for the microbial surfactant synthesis. The microorganism was able to g

10. Evaluation of the composition of culture medium for yeast biomass production using raw glycerol from biodiesel synthesis
The work herewith investigated the production of yeast biomass as a source of protein, using Yarrowia lipolytica NRRL YB-423 and raw glycerol from biodiesel synthesis as the main carbon source. A significant influence of glycerol concentration, initial pH and yeast extract concentration on biomass and protein content was observed according to the 2v5-1 fract

11. Production of bioemulsifiers by Yarrowia lipolytica in sea water using diesel oil as the carbon source
The objective of this work was to investigate, on a flask scale, the production of bioemulsifiers by Yarrowia lipolytica in the presence of sea water, supplemented with nitrogen and phosphate sources, using diesel oil as substrate. A full 2(4) factorial design was conducted to investigate the effects and interactions of the nutrient concentrations (diesel oi

12. DESENVOLVIMENTO DE BIODETERGENTES UTILIZANDO BIOSSURFACTANTES COMO MATÉRIA-PRIMA. / DEVELOPMENT OF USING BIODETERGENTES BIOSURFACTANTS AS RAW MATERIALS.
A maioria dos surfactantes disponíveis comercialmente é sintetizada a partir de derivados do petróleo, representando assim uma importante fonte de poluição, causando efeitos biológicos adversos a organismos aquáticos. Na indústria de detergentes, apesar das várias marcas disponíveis no mercado serem consideradas biodegradáveis e amparadas pela leg
