Resumen:
Un instituto de investigación rumano ha desarrollado una tecnología para obtener bioetanol a partir de madera mediante un método simultáneo de sacarificación y fermentación (SSF). La tecnología consiste en los siguientes pasos: 1) pretratamiento con explosión por vapor a alta temperatura y presión, 2) hidrólisis enzimática y fermentación de celulosa en bioetanol y 3) destilación de bioetanol. El instituto busca socios industriales especializados en la producción de biomasa y biocombustible para desarrollar, validar y fabricar la tecnología y establecer acuerdos comerciales con asistencia técnica (ingeniería y asistencia técnica).

Technology for bioethanol production from wood using simultaneous saccharification and fermentation (SSF) method
Summary:
A Romanian research institute has developed a technology for obtaining bioethanol from wood, by simultaneous saccharification and fermentation (SSF) method. Industrial partners active in biomass and biofuel production are sought for, in order to develop, validate and introduce the new technology into production, for commercial agreement with technical assistance (engineering and technical assistance).
Description:
A Romanian research institute with a remarkable endowment that allows the approach of projects from research to the prototype realisation and technological transfer has developed a technology for obtaining bioethanol using simultaneous saccharification and fermentation (SSF) of wood. This method combines two processes into one.
The Romanian institute is specialized on the development of technologies for biofuel obtaining (bioethanol, biodiesel and biogas) from renewable resources, as well as on application of extraction techniques for extraction and characterization of different products and co-products.
The technology for converting wood into bioethanol using simultaneous saccharification and fermentation consists in the following steps:
- steam-explosion pre-treatment at high temperature and pressure;
- enzymatic hydrolysis and fermentation of cellulose into bioethanol;
- distillation of bioethanol.
In other foreign countries, there are facilities for the production of first generation biofuels, which include ethanol produced from corn and sugar beet and biodiesel, but there are no industrial plants producing bioethanol from cellulosic biomass (mainly sawdust). Bioethanol is produced by fermenting sugar made from grain that is enzymatically hydrolyzed to monosaccharides and then fermented with yeast from bioethanol. Abroad there are not industrial plants producing bioethanol from cellulosic waste saccharification method simultaneously with fermentation. There are plants of reduced capacity that produce biofuel by this method.
In Romania there is no other technology for producing bioethanol from waste cellulose (sawdust) by saccharification simultaneously with fermentation, and there are no industrial plants or small capacity to operate and produce fuel from waste cellulose (sawdust).
The Romanian research institute is looking for industrial partners, in order to develop, validate and introduce the new technology into production, for commercial agreeement with technical assistance (engineering and technical assistance).
Advantages and Innovations:
·Bioethanol is an attractive alternative fuel because it is a renewable bio-based resource and it is oxygenated thereby provides the potential to reduce particulate emission in compression-ignition engines;
·The pre-treatment of wood enhance the accessibility of the wood to the enzymes;
·SSF method combined the enzymatic hydrolysis and fermentation of sugars in a combined step;
·SSF method gives higher bioethanol yields and requires lower amount of enzyme because end-product inhibition from cellobiose and glucose formed during enzymatic hydrolysis is relieved by the yeast fermentation;
·SSF technology increase of hydrolysis rate by conversion of sugars that inhibit the cellulase activity;
·Lower requirements for sterile conditions since glucose is removed immediately and bioethanol is produced;
·Shorter process time.
