    Abstract: The present specification discloses a composition comprising a plurality of diols which is useful for the production of polyester bottles, wherein the diols are mainly obtained from the conversion of a ligno-cellulosic biomass feedstock stream. The composition comprises ethylene glycol and at least one diol selected from the group of diols having a formula of CH(OH)2, wherein n is the total number of carbons and is an integer in the range from 3 to 20, z is an integer in the range from 0 to 2n, and C1 and C2 are each attached to one of the OH groups of the formula (e.g. 1,2-Propylene glycol, 1,2-Butanediol and 1,2-Pentanediol) and wherein the composition is substantially free of diols which absorb light at a wavelength of 275 nm, so that the percent light transmission of the composition at a wavelength of 275 nm is greater than 40%.

    Abstract: It is disclosed a continuous process for producing a polyols stream comprising ethylene glycol and propylene glycol, wherein a liquid sugar stream comprising water and at least a monomeric sugar is introduced into a first reaction zone and subjected to a first reaction, which is a hydrogenation reaction of the at least a monomeric sugar, at a first catalytic conditions and in the presence of a first hydrogen gas to produce an hydrogenated mixture comprising at least a sugar alcohol. At least a portion of the hydrogenated mixture and at least a portion of the first hydrogen gas are then transferred to a second reaction zone and subjected to a second reaction, which is a hydrogenolysis reaction of the at least a sugar alcohol, at second catalytic conditions to produce a hydrogenolysis mixture comprising at least a polyol. The second reaction occurs in the presence of a second hydrogen gas, wherein the second hydrogen gas comprises the portion of the first hydrogen gas which has been transferred to the second reaction. The first reaction is conducted at a first reaction pressure which is greater than or equal to the second reaction pressure, and the hydrogen gas is then released at the end of the conversion process of the second reaction zone at a discharge pressure which is less than the pressure of the first reaction. In this way, the transferring of at least a portion of the hydrogenated mixture and at least a portion of the first hydrogen gas from the first reaction zone to the second reaction zone may be done without the use of any pumping system, specifically of a pumping system which is capable of pumping a pressurized liquid/gas mixture.

    Abstract: It is disclosed a non-naturally occurring microbial organism comprising at least one exogenous nucleic acid encoding an enzyme, or a portion thereof, selected from the group of ammonia lyase. Preferably, the enzyme is PAL3, and the at least one exogenous nucleic acid is obtained from Arabidopsis thaliana. The non-naturally occurring microbial organism has an increased resistance to biochemical stress compared to the starting microbial organism, as induced for instance by oxidative stress or organic acid stress. Preferably, the non-naturally occurring microbial organism is a yeast and it may be used for fermenting a carbon source obtained from a ligno-cellulosic feedstock.

    Abstract: A process produces at least a first enzyme from a host cell, wherein the first enzyme is capable of hydrolyzing a first pre-treated ligno-cellulosic biomass. The process comprises the step of cultivating the host cell to produce at least the first enzyme for a cultivation time, wherein the cultivation of the host cell occurs in a sugar depleted cultivation environment comprising the host cell, water and a solid composition comprising a complex sugar of the solid composition and a lignin of the solid composition. In such a process, the solid composition is obtained from a second pre-treated ligno-cellulosic biomass, comprising a complex sugar of the second pre-treated ligno-cellulosic biomass and a lignin of the second pre-treated ligno-cellulosic biomass; and the ratio of the total amount of the complex sugars of the solid composition to the total amount of the lignin of the solid composition is greater than zero and less than the ratio of the total amount of the complex sugars of the second pre-treated ligno-cellulosic biomass to the total amount of the lignin of the second pre-treated ligno-cellulosic biomass.
