Abstract: An oleaginous yeast strain of the species Trichosporon oleaginosus, deposited on May 28, 2020 at Leibniz-Institut DSMZ, deposit number DSM 33530 can be used in the production of lipids by fermentation and was obtained by mutagenesis and subsequent selection from the oleaginous yeast strain of the species Trichosporon oleaginosus DSM 32508. The strain DSM 33530 is characterized by high thermotolerance, such as to allow the fermentation temperature to be increased compared to conventional processes and still guarantee the vital functions of the microorganism during fermentation itself.

Abstract: Integrated process for the production of bio-oil from sludge coming from a wastewater purification plant comprising the following steps: (a) sending wastewater to said purification plant obtaining sludge; (b) subjecting the sludge obtained in said step (a) to liquefaction, obtaining a mixture Including an oily phase consisting of bio-oil, a solid phase and an aqueous phase; (c) sending the aqueous phase obtained in said step (b) to said purification plant. The bio-oil (or “bio-crude”) thus obtained can be advantageously used in the production of bio-fuels which can be used as such, or in a mixture with other automotive fuels. Otherwise, said bio-oil (or “bio-crude”) can be used as such (bio-fuel), or in a mixture with fossil fuels (combustible oil, coal, etc.), for the generation of electric energy or heat.

Abstract: A process for the conversion of lignin to liquid hydrocarbons comprising: (1) hydrogenolyzing a lignin in the presence of at least one hydrogenolysis catalyst, at a temperature ranging from 250° C. to 350° C., preferably ranging from 290° C. to 320° C., to obtain depolymerized lignin; and (2) hydrodeoxygenating said depolymerized lignin in the presence of a hydrodeoxygenating catalyst to obtain a mixture of liquid hydrocarbons. The resultant liquid hydrocarbons can be used as such (biofuels) for the production of reformulated gasolines, or they can be used for the production of gasolines or oils by conventional refining processes.

The obtained fermentation broth comprises oleaginous cellular biomass which is subjected to microfiltration for the isolation of lipids. Said lipids can be used in the production of biodiesel or green diesel.

Abstract: The cultivation of heterotrophic and phototrophic micro-organisms is integrated for the production of bio-oil for biofuels, wherein the overall algal suspension produced is first thickened, with recirculation of the excess water to cultivation containers, and then thermally treated at a high temperature. After cooling, a bio-oil phase is recovered together with a suspension rich in soluble carbohydrates and proteins which forms a nutritional/energy source for heterotrophic micro-organisms.
