The immobilization of Saccharomyces cerevisiae DSM 70424, Saccharomyces ludwigii DSM 3447 andSaccharomyces rouxii DSM 2531 on brewer's spent grain and then ethanol production and sugar consumption of these immobilized yeasts were investigated. The aim of this study was to investigate the abilities of these three immobilized yeasts for producing alcohol for brewing at two temperatures (7 and 12 °C) using two different sugar levels (one at original level supplied in the brewery and one with 2.5% (w/v), added glucose to the wort).Increasing both parameters resulted in higher alcohol production by all the yeasts studied. At 7 °C and with original wort density the ethanol content at the end of fermentation was 2.7% (v/v) for S. cerevisiae, 1.7% for S. ludwigii and 2.0% for S. rouxii. After the addition of 2.5% (w/v) glucose at the same temperature (7 °C), the alcohol production was increased to 4.1, 2.8 and 4.1%, respectively. Similar improvements were observed when the fermentation was carried out at 12 °C with/without the addition of glucose to the wort.However, temperature indicated greater influence on S. ludwigii than did on S. rouxii and S. cerevisiae. The immobilization as carried out in this study impacted both S. ludwigii and S. rouxii in a way that they could consume maltose under certain conditions.

“…This method has been extensively exploited in enzyme immobilisation. It was realised that to achieve high efficiency binding, stability is to be enhanced, and this could be achieved by creating covalent link- Saccharomyces cerevisiae has been immobilised on silanised silica beads using α-aminopropyl triethoxy silane as a coupling agent (Navarro and Durand 1977 ). Pseudomonas stutzeri has been immobilised on polyethylene surface by chlorosulphonic acid and chlorosulphonic acid combined with polyethyleneimine (Choi et al 1999 ).…”

“…It is related to the research on the influence of the biofilm structures on the characteristics of microorganisms forming the biofilm. Interesting results were published on the modification of oxygen consumption rate of microorganisms, as a result of their immobilization as biofilm (23). Very interesting data were reported on the decrease of the sensitivity of spontaneously immobilized microorganisms to variations in temperature (25,26), acidity (24), concentrations of substrates (26) and products (27), as well as on the increase of the cell activity in the biofilm (26,27).…”

The research results published in the last 20 years in the field of biofilms are reviewed in this study. The information available was treated from the point of view of the system approach. On the basis of this approach, the biofilm system is decomposed into three subsystems -carrier, biofilm and fluids in the vicinity of the biofilm. This allows to summarize the knowledge on each of the subsystems and to reveal the relationships and interactions between them. In this first part of the study, the knowledge on biofilm carriers will be critically discussed.
