P~cteclytic activity in Hanse~u!a ~ and cube= ye~s=s was evaluaued using bovine serum albumin (BSA) and casein as ~ducer3 of p=oteasee. Since these p=oteLns were incocpc=~ted ~n a simple mod-ium ccnuaining glucose and ~east Niu=ogen Base (~o la~..i~a acids and (:~H,):S~,) (YNB), six of cur yeas:s degraded both protslns, hun only H. anc~a~a and isoLaue 20a- 4 exc=eued up to 0.7 unit prouease/ml, cul~ure su~e=na:an~ within 2 days of gr=wuh. Also, casein appeared uo be superior uo BSA as inducer of p=o=ease by obese yeasus. C. caseLnolvu~ca deg=aded casei~ bu~ no~ BSA, and failed :~ excreue protease in :his simple medium. Since the hl;hly protaolyti= yeas:, C. caseino~vclca failed to produce pc=tease in uhe simple medium used earils=, we decided ~o tssu enzyme pc=duo:ion in a complex medium c===aini~; ¢.-yptc~e.

The o:he~ yeasua when ~esued on this ~sdiu~, while showing p=ouein decomposition, did no~ produce exccel!uls: pretense. i: appears uhau R. one,ale does n=u pz¢duce exoceilula= p=cuease in a medium conualning uryptone, while C. c~s~o~,~c~c~ needs :he lau~er for enzyme seems:ion. To confirm these conclusions we decided ~o ~esu for exoce!lulaz enzyme p~oducuion in ~ diffs=ent media described in Table 6. F=om :his ~a~is i~ will be seen ~hat C. caseino~v:~c~ produces de~ecuabls ~oun=s of p==usase in medium 1 which c=nuains t=ypuonm and as additional carbon sour=s, soluble snatch and g~ycerc!, Lnsused of glucose.

T=yp=one and casein ¢oncnn~rauions were increased ~o 0.75% and 2.0% respectively, and sucrose was used insuead of glucose, C. caseino~vnica produced large amounUs of proueasa in ~he media which conuain 0.75% :=yp=one and casein. Sucrose, unlike glucmse, did no= suppress enzyme secretion by =his yeas=. ProUease producuion by ~his yeas= was negligible in ~he simple medium and only a re!auively small amounu of enzyme was de=eccad on day 7. In ~he nex~ experimen= ~/p=one concentration was increased ~c 2.0% (medium no. 2) and sucoose and glucose were compared for their effecu on enzyme secretion by C. caseinolvtica. From the results of ~his experimenu, presenusd in Table 7, it will be seen ~haU C. caseino!v~ica elaborates large amounus of pro~ease in ~he two complex media containing glycerol soluble e~arch or sucrose as addiuional carbon sources. Zncreasing ~he nrypnone concenura~ion from 0.75% no 2.0% nearly doubles ~he secretion of procease (day 4 - medium 2 versus medium i). When glucose is used as addi¢ionai carbon source, pcotease pr=duculon by C. case£nolvtica is shu¢ down completely and prouein in ~he medium remains unused even after I0 days (medium 3). Sucrose, on ~he ocher hand, permi:s procsasa secreuion ccmparable ~o glycerol-scorch (medium 4).
