A process for bio-1,3-butanediol purification from a fermentation broth includes the steps of: (a) subjecting the fermentation broth to separation, (b) subjecting the product obtained in step (a) to treatment with ion-exchange resins, (c) subjecting the product obtained in step (b) to a first evaporation, (d) subjecting the product obtained in step (c) to a second evaporation; and (e) subjecting the product obtained in step (d) to a third evaporation, obtaining purified bio-1,3-butanediol. The purified bio-1,3-butanediol can be used to produce bio-1,3-butadiene. Bio-1,3-butadiene can be used as a monomer or as an intermediate to produce elastomers and (co)polymers.

A process for production of sugars from biomass derived from guayule plants includes placing a certain amount of the biomass in contact with a certain amount of water and with at least one organic acid. The sugars thus obtained may advantageously be used as sources of carbon in fermentation processes for the production of alcohols, lipids, diols, or in chemical synthesis processes for the production of other intermediates or chemicals.

A method for concentrating, in order to favour the subsequent extraction process of intracellular lipids, a cell suspension containing a biomass of oleaginous yeasts fermented in fermentation broth under conditions that allow the intracellular accumulation of lipids, where the biomass contains significant quantities of mucilaginous material. The method includes:
