Therefore it is important to know how starch content and its characteristics like size, cell thickness change starch digestion in gastrointestinal tract. Slide 4 In mammals starch is hydrolysed by enzymes into glucose through several steps. The first step takes place in the mouth were the salivary alfa-amylase reacts, but its efficiency degrades when it reaches the stomach. In the stomach different digestive fluids, which contain starch degrading enzymes, do the hydrolysis. The third step and the majority of starch hydrolysis takes place in small intestine where pancreatic alfa-amylase break the most bonds and creates new products. The fourth and last stepi s hydrolysing the remaining oligosaccharides by the brunch border enzymes of the intestine. The starch digestion in mammals and humans is very similar due to the build of the gastrointestinal tract and enzymes in that tract. Slide 5

See bakter on kasulik ka selle poolest, et toodab tselluloosi lagundavaid ensüüme, vähendades vajadust väliste ensüümide järgi 50 protsendi võrra. Näited 2008 Louisiana osariigis paiknev Verenium on esimene tselluloosist etanooli tootev tehas USAs, mis on kavandatud pidevalt töötama. Seni on tselluloosist etanooli toodetud lühiajaliselt erinevate pilootprojektide käigus. Abengoa S.A. 1941 uses an innovative enzymatic hydrolysis process to convert non-edible corn stalks, stems and leaves into up to 25 million gallons of ethanol per year. The project maximizes the use of agricultural crop residues that would otherwise remain idle, and utilizes feedstock that does not compete with feed grains. Natuke infot Eesti ebaõnnestumiste kohta Balti mere idakalda riikides arvestatavaid bioetanooli tootjaid ei ole.

TaqMan® probes utilize the 5' exonuclease activity of the enzyme Taq Polymerase for measuring the amount of target sequences in the samples. TaqMan® probes consist of a 18- 22 bp oligonucleotide probe which is labeled with a reporter fluorophore at the 5' end and a quencher fluorophore at the 3' end. TaqMan® probe functioning
