HiiHin^ on tlie oni' Ijund 011 the iiuifregn.iliility of saecharose, 

 aixl on the susceptihility to dissociation of tlie hexoses on the 

 otlitT, (J.wox (IV.) has atU-nipted t<» (dal.urat.' a prcx-ess for 

 extim-tin',' supu- from niohissi-s. The cliief feature of tlie pro- 

 cess is the decomposition, by Miu-or cin-iric/foiihs, of the invert 

 siipir, which, as is well kn(.wn, prevents the crystillisiition of 

 the acconipanyin'.' saccharose in molasses; the resultin;; alcohol 

 is then distilled off, and the s^iccharose is finally sepamtcHl from 

 the residue by crystiillisiition. 



In the n)anufacture of snnfT, a certjiin part seems to be 

 played by the intramolecular respinition of Mwui-k, especially in 

 connection with the after-fernjentjition in the so-called " jiig- 

 tails" to which reference has alrea<ly been made in § 105. 

 Here, as also in toljiicco pressed into casks, Miciol (I.) verv 

 often found Miwor tnurr,/,), in addition to the Sj>uro<finia i/raw/ig 

 at that time known as Man,,- jlarUlu.<. J. iiEiiitEXs (III.) after- 

 wards found a second species {Miiror rai->'iii'isu.<) both in tlie pig- 

 tiil.s and on tobacco leaves, both jrreen and dry ; and he also 

 observed that this latter organism acts therein lis a prcxlucer of 

 alcohol, drawing upon the sugar contiiined in the " sjiuces " 

 (Jj 1051. On the other hand, he rarely succeeded in finding 

 Mucor species on tobaccos that weie not treated with "' s;iuce." 



With regard to the part played by Mucors in turning bread 

 moulily and in the rotting of fruit, this and correlative questions 

 will be dealt with in the final section. 



O. Johax-Olsen (II.) in dest-rilting the prepanition and com- 

 position of (Jammelost (a Norwegian chee.se), states that certain 

 species of '' -.l///<-.<r msei, and Chlaini/ddiimcor canci, luith 



new .specie pjiit in the ripening of this piiKluct. The 



experiments of Weiu.m.v.v.v (X.) confirmed that, owing to their 

 strongly develoj)ed capacity for degniding ea.sein, fungi of this 

 kind are able to take part in the ripening of chee.se, and also 

 to allect the fiavoui- of the article l>y forming pungent fission
