Proteins are essential constituents of animal feeds, which comprise mainly vegetable protein (e.g., soybean meal), is produced and transported globally. The decoupling protein-production livestock-growth areas results in deficiencies certain parts the world, significant environmental stress. Alternative, more sustainable feeds necessary to meet increasing needs, decrease footprint products. Yeast Single Cell (SCP), locally using various agro-industrial by-product streams, have potential as...
Yarrowia lipolytica is a well-studied oleaginous yeast known for its ability to accumulate and store intracellular lipids, while growing on diverse, non-conventional substrates. Amongst them, crude glycerol, low-cost by-product of the biodiesel industry, appears be an interesting option scaling up sustainable single-cell oil production process. Adaptive laboratory evolution (ALE) powerful tool force metabolic adaptations endowing tolerance stressful environmental conditions, generating...
Biodiesel is synthesized by the transesterification of triglycerides oils with short-chain alcohols, such as methanol and ethanol. According to Renewable Energy Directive guidelines (RED II 2018/2001/EU) contribution advanced biofuels, which do not include edible oils, towards overall EU target, at 1% in 2025 least 3.5% 2030. Bioprocesses that valorize non-edible for production second-generation biodiesel could play a critical role achieving this goal. Immobilized lipases, well other enzyme...
BACKGROUND Wine waste lees are currently partly exploited for tartaric acid (TA) production, through an environment-offensive process, while concurrently occurring bio-active polyphenolic compounds wasted. This paper, deals with the development of integrated, environment friendly using mild conditions, recovering TA simultaneous exploitation total polyphenols (TPP) from wine lees. RESULTS A first process step, described in a previous publication, yields liquid stream containing approx. 44.2...
Municipal Solid Waste (MSW) management has been a major problem of modern cities for many years. Thus, the development optimal waste strategies priority European Commission, especially in transition toward circular economy. In this paper, an analysis different MSW treatment methods that can be effectively implemented Region Central Macedonia (RCM) is provided, and their comparison from environmental point view performed. The assessment based on real data indicated recently updated Greek...
Abstract Background A potential alternative to lactic acid production through sugar fermentation is its recovery from grass silage leachate. The separation and purification of broths remain a key issue, as it amounts up 80% industrial cost. In this study, genetically engineered E. coli strain (A1:ldhA), that cannot catabolize acid, has been used selectively remove impurities synthetic medium comprising typical components (i.e., glucose acetic acid) green systematic approach followed provide...
The use of recycled ultrafiltration (r-UF) membranes, originating from end-of-life reverse osmosis as submerged flat-sheet membranes in an aerobic membrane bioreactor (aMBR) system is described herein for the first time. A feasibility study this new approach was performed a laboratory-scale aMBR system. r-UF performance evaluated terms permeability, fouling behavior, and permeate quality using widely used commercial flat sheet microfiltration (c-MF) reference. Tests were conducted under...
Food systems and, to an extent, the pig sector are major contributors of greenhouse gas (GHG) emissions globally. At same time, significant amounts waste produced from food sector. The aim this study is examine implementation circular bio-economy practices in Greek improve its environmental performance. More specifically, collaboration with a farm Northern Greece and management company, collection processing bakery by-products was organized produce meal (BM) integrate it diets fattening...
The present study investigated the dietary impact of dried olive pulp (OP) on growth performance, gut health and some welfare behavior characteristics broilers. It was conducted in a commercial poultry farm using 108 13 day-old Ross male Chickens were equally randomly assigned to 3 treatments, CON, OP3 OP6, based incorporation rate OP ration (0%, 3%, 6%, respectively). A beneficial foot pad dermatitis (FPD) feather cleanliness OP-fed broilers recorded. No adverse effects qualitative...
BACKGROUND Table olive processing wastewater (TOPW) is a seriously polluting and difficult to treat effluent, characterized by widely fluctuating pH salinity, as well high concentrations of organic matter polyphenols. This systematic long-term study in laboratory-scale pilot demonstrates that membrane bioreactor (MBR) technology effective substantially bio-degrading TOPW. RESULTS After implementation an appropriate protocol active biomass acclimatization/proliferation, the MBR was operated...
Extraction of intracellular lipids the oleaginous yeast Yarrowia lipolytica has been systematically studied aiming towards a sustainable extraction process for lipid recovery. Selection suitable industrial (bulk) solvents and parameters that lead to maximization recovery are significant issues be addressed, with applications motivating this study. Biomass from fermentation (MUCL 28849) was used in small laboratory tests assess different solvent mixtures (i.e., methanol/hexane,...
This study investigated the dietary impact of dried Yarrowia lipolytica yeast (YLP) on growth performance, meat quality, welfare and behavior indicators broilers. It was performed in a commercial poultry farm using 108 13 day-old Ross 308 male The chicks were randomly equally divided into three groups CON, YLP3 YLP5, according to incorporation rate YLP feed (0%, 3%, 5%, respectively). A positive effect foot pad dermatitis (FPD) YLP-fed broilers observed without any adverse effects welfare,...
