Batch alcohol production with immobilized cells. 200-litre reactor


, : Batch alcohol production with immobilized cells. 200-litre reactor. Revista ICIDCA Sobre los Derivados de la Cana de Azucarrecd 1995; 26(2): 1-6

A bioreactor packed with balsa chips as support for yeast was used to produce alcohol from cane molasses without previous clarification or sterilization. During the adsorption and propagation the operating variables were pH 4.2 +or- 0.2, temperature 32 +or- 2 degrees C, aeration rate 150 litres/min; for the alcoholic fermentation stage, only the aeration was altered, being decreased to 10 litres/min.

The aphid population on potato plants was estimated by counting aphids on 100 randomly chosen leaves from upper, middle, and lower parts of the plant. This was usually done during a period of 14 days in mid-July in 5-10 potato fields in each of 5...

In an experiment at the SISSI-LISE3 facility of GANIL, the decay of the proton drip line nucleus 45Fe has been studied. Fragment-implantation events have been correlated with radioactive decay events in a 16x16 pixel silicon-strip detector. The de...

Primary central nervous system lymphoma (PCNSL) is sensitive to both chemotherapy and radiation, but the blood-brain barrier limits the usefulness of the most effective chemotherapeutic agents. On the other hand radiation therapy carries along ser...
