This paper reviews the importance of maintaining low temperature storage and handling (i.e., cold chain) for animal serum through all stages of processing, from finished product to the actual end-user. This cold chain extends from serum manufacture through the irradiation process, during shipment back to the supplier post-irradiation, as well as storage at supplier, irradiation, and end-user facilities. Anecdotal experience and theoretical considerations emphasize the point that maintenance of the cold chain is necessary for preserving the performance of serum for cell culture and other applications…

Fermentation utilizes organic substrates and organic electron acceptors to produce reduced organic substances as end-products. Bioethanol has a number of advantages over conventional fuels because it is produced from renewable resources. Ethanol is a high octane fuel that can replace lead as an octane enhancer in petrol by helping to oxygenate the fuel mixture so it burns more completely and reduces polluting emissions. The burning of ethanol more closely represents a natural carbon dioxide cycle since the released CO2 is recycled back into plants where the carbon dioxide becomes the carbon source for new sugars, starches and cellulose…
