    Abstract: The present invention relates to a method of identifying a heterologous polypeptide having enzymatic activity for converting pyruvate, acetaldehyde or acetate into acetyl-CoA in (the cytosol of) a yeast cell comprising: a) providing a mutated yeast cell comprising a deletion of at least one gene of the (PDH) by-pass, selected from the genes encoding the enzymes pyruvate decarboxylase (PDC), acetaldehyde dehydrogenase (ALD), and acetyl-CoA synthetase (ACS); b) transforming said mutated yeast cell with an expression vector comprising a heterologous nucleotide sequence encoding a candidate polypeptide having potential enzymatic activity for converting pyruvate, acetaldehyde or acetate into acetyl-CoA; c) testing said recombinant mutated yeast cell for its ability to grow on minimal medium containing glucose as sole carbon source, and d) identifying said candidate polypeptide as a heterologous polypeptide having enzymatic activity for converting pyruvate, acetaldehyde or acetate into acetyl-CoA in (the cytosol of) said yeast cell when growth of said cell is observed. The invention further relates to a method of producing a fermentation production such as butanol.

    Abstract: A knee area protection apparatus for the protection of a vehicle occupant is provided which includes a deployment guiding plate and a support plate each having a top transverse edge, a bottom transverse edge, and side edges. The support plate is securable to the vehicle in a lower area of a seat compartment thereof. The knee area protection apparatus also includes retaining bands to retain and guide an air bag sack as it is deployed as well as to retain and guide the deployment guiding plate, which is moved by the deployment of the air bag sack.
