“…As is known, acetic fermentation was the first biological proc ess on which the validity of the dehydrogenation theory was tested (19). Wieland (21), however, the formation of alco hol (process III) should be !�iven an important position in aerobiosis to agree with Neuberg's ideas (22). The production of nascent inter mediate substances in cell metabolism should bring about an accelera tion of the reaction so that from the results of the reaction nothing can be concluded about its course.…”

“…The term hydrotropy was first introduced by Neuberg in 1916 (1,2), who studied the solubility increase of organic compounds in water by the addition of certain compounds, i.e., hydrotropes. Hydrotropic solubilization of organic compounds was then described in a number of articles (3)(4)(5).…”

The hydrotropic effect of different alkyl polyglucosides (APG) has been studied and compared with a model hydrotrope, toluol-4-sulfonic acid. The effect has been assessed by two different methods: (i) as the cloud point elevation of a solution containing different nonionic surfactants upon addition of the hydrotrope and (ii) the destabilization of liquid crystalline phases in a ternary system. The effect of the hydrophobic alkyl group length was found to be opposite in the two methods. APG with intermediate alkyl chain lengths (octyl and decyl) was shown to be very effective in elevating the cloud point, while APG with a short (butyl) group was the most efficient in destabilizing liquid crystalline phases in the system of water, sodium dodecyl sulfate and pentanol. Effects on phase behavior and cloud point elevation with addition of an APG are highly dependent on its structure. However, the correlation between structural effects as observed in the two methods requires further study. JSD 1, 485-489 (1998).
