Indeed, lignocellulosic biomass can be transformed into energy and fuels through a variety of chemical, thermo-chemical and biological conversion processes.
Consequently, the economics of biological conversion processes has improved.
Alternatively, these sugars can also be used to produce various hydrocarbon products through biological conversion processes.
In some biological conversion processes, pollutants in crude glycerol, inhibit cell and fungal growth and result in lower production rates and product yields (compared with pure or commercial glycerol under the same culture conditions).
In order to produce drop-in fuels from biomass, combined chemical and biological conversion processes are used to produce liquid fuels adaptable to the current internal combustion engine design [ 1].
Many of these utilize a cell wall deconstruction strategy involving chemical pretreatment followed by enzymatic hydrolysis of the cell wall polysaccharides into sugar intermediates that can be subsequently utilized in chemical or biological conversion processes [ 4– 7].
Given that acetyl-CoA is a key intermediate in several biosynthetic pathways, phosphoketolase overexpression offers a viable strategy to enhance the economics of an array of biological methane conversion processes.
The SSCF concept is one of the interesting process options and the potential of such process for biological conversion of lignocellulosic raw materials to bioethanol in large scales has to the best of our knowledge not been reported previously.
The CMM is described by applying it first to a simple conversion process in the biological reactor yielding an ODE solver, and then to the solid liquid separation in the secondary settling tank, yielding a PDE solver.
Together, these results suggested that although the IPSC conversion process resets the biological clock, other important measures of cell fitness such as mitochondrial function, is either not improved or is even slightly compromised compared to input cells.
