The invention provides a mutated yeast strain which grows to a higher specific biomass than the wild-type strain, wherein the mutation modulates the expression of at least one mitochondrial carrier protein.

The method may further include densifying the torrefied biomass into pieces having a second specific density greater than a first specific density of the torrefied biomass prior to densification.

Further provided is an enzyme selected from a specific exo-type cellulase, a specific endo-type cellulase and a specific processive endo-type cellulase as an enzyme or a group of enzymes for decomposing a soft biomass.

species composition, abundance and/or biomass (spatial and temporal variation)

Growth rate (average specific growth rate): is the logarithmic increase in biomass during the exposure period.

In a specific embodiment the biomass feedstock comprises at least 10 wt% triglycerides.

As a specific application, this process is utilized as a part of biomass to liquid (BTL) process.

1 Biomass and biomass products

The test endpoint is inhibition of growth, expressed as the logarithmic increase in biomass (average specific growth rate) during the exposure period.

The supplied biomass is preheated here by mixing the supplied biomass with the hydrolysed biomass.

The inventive method for transforming biomass makes it possible to use the biomass as a clean ecological fuel and produce activated charcoal possessing a high specific surface of a value of 280 to 500 ml/100g.

The algal biomass may be whole algal biomass, residual algal biomass, or both.

Average specific growth rate: this response variable is calculated on the basis of the logarithmic increase of biomass during the test period, expressed per day.

The invention is to a novel method for evaluating the hydrolysis conversion of a enzyme or enzyme mixture relative to a specific ligno-cellulosic biomass.
