In this analysis we have also included the effect of the aqueous phase composition (pH, sugars, ethanol, hydrocolloids, salts, etc.) and the processing conditions (temperature). By incorporating solutes in the aqueous phase, we hope to approach the behavior of a simple well-defined model of complex, real food formulations.

Braskem, a Brazilian company, began producing biobased polyethylene on a commercial scale in 2010 [7]. The starting material is sugar cane. Conventional fermentation methods are used to produce ethanol from sugar. Ethanol is then dehydrated to ethylene. This ethylene can then be used to produce polyethylene, exactly as is done with ethylene from petrochemical sources. The resulting polyethylene is identical in performance to conventional polyethylene, and of course is not biodegradable. 

Biomass production on Earth corresponds to around 120,000 Mt per year. However, only 5% of that biomass is captured and used by hirmans, and of those 6,000 Mt, only 5% is not destined for energy or food usage. Thus, 300 Mt are already used for chemistry. Yet these quantities are fairly close to the 500 Mt of fossil resomces used annually for chemistry, so we can see the significant potential for substitution of fossil resources by increasing use of renewable resources. The resomces ttsed essential are starch and its derivatives - sugar, ethanol, etc. - cellulose, vegetable oil and glycerol, plant fibers, etc. 

It is worth emphasising that the original state of a solute has no bearing on the nature of the solution. Particle diagrams for solutions of sugar, ethanol and ammonia look the same save the different solute particle shapes (Figure 2.7). A dissolved substance does not have a state as such.

Equations (6.130), (6.134), (6.137), (6.138), and (6.143) 6.149) are the model equations that are to be solved together with the physical properties, external mass transfer, and diffusivities correlations to obtain the change of sugar, ethanol, and micro-organism concentrations with time. 

A few fungal strains have shown high tolerance to sugar, ethanol and toxic substances present in the hydrolysate. Therefore, these strains may be considered potential for ethanol production from a mixture of sugars in the hydrolysate. However, systematic studies on the biochemical mechanism for ethanol tolerance in fungi has not been conducted so far. This is of great interest since improved strains with increased tolerance will be more productive.
