855. Palma, Stefano di. Uso del rifatto nella fabbricazione delta cellulosa per carta. 

 (The use of residues from the manufacture of licorice [from Glycyrrhiza glabra L.] in the produc- 

 tion of cellulose for paper manufacture.] Staz. Sper. Agrarie Ital. 53: 393-394. 1920. — The 

 fiber, decoloi-ized with calcium hypochlorite or other bleaching substance, becomes light col- 

 ored without losing its consistency, contains 6 per cent of ash and about 50 per cent of cellulose, 

 and constitutes, according to the author, a valuable substitute for wood and rags in the manu- 

 facture of paper. — A. Bonazzi. 



856. Pantanelli, E. Produzione di alcool dal fico d' India. [The production of alcohol 

 from Opuntia.] Staz. Sper. Agrarie Ital. 53: 451-470. 1920. — After a review of the literature 

 on the subject the author attempts to study the course of natural alcoholic fermentation in 

 the untreated pulp of the fruit of Opuntia vulgaris and 0. amyclea. He found the fermentation 

 to be unsatisfactory owing to the development of a large number of organisms injurious to the 

 fermentation, among them the Saccharomyces opuntiae of Ulpiani and Sarcoli. Boiled pulp, 

 or pulp to which had been added 0.03 per cent of potassium metabisulphite, when inoculated 

 with what appears to be a bottom yeast, yielded an excellent liquor with a slightly aromatic 

 ethereal odor and a high alcoholic content (9000 cc. of anhydrous ethylic alcohol for each 100 

 kg. of pulp). The best results were obtained with the must treated with bisulphite; and the 

 fact was ascertained that, in the fermentation of this corrected raw pulp by a selected culture, 

 a certain quantity of glucoside sugar was utilized for alcohol production — the fermentation 

 thus yielding a greater quantity of alcohol than could be predicted by a consideration of merely 

 the reducing sugars, as such, contained in the fruit. The bisulphite-treated pulp appears to 

 give a better product than the boiled pulp since in the process of boiling the changes caused 

 by the enzjTnes of the mature fruit are interfered with. Fruit attacked by Ceratitis capitata 

 give an unsatisfactory product. — A. Bonazzi.
