Abstract
U radu je istraživana koflokulacija neflokulentnih stanica kvasca S. cerevisiae s flokulentnim stanicama pivskog kvasca S. uvarum. Koflokulacija je brzi proces (5 minuta), odvija se u širokom rasponu pH vrijednosti (3,0-8,0) i zahtijeva malu količinu kalcija (0,1 mM). Učinak miješanja je utjecao na agregaciju kvasca, no miješanje između 60 okr/min i 80 okr/min imalo je vrlo mali učinak na proces koflokulacije, dok je miješanjem uzoraka pri 100 okr/min postignut 91%-tni učinak koflokulacije, a pri 140 okr/min 94%-tna koflokulacija. Flokulentne stanice S. uvarum imaju sposobnost taloženja neflokulentnih stanica S. cerevisiae, što pokazuje prikladnost koflokulacije za separaciju različitih tipova neflokulentnih stanica.
Abstract (english)
Co-flocculation of non-flocculent yeast S. cerevisiae cells by addition of flocculent brewer’s yeast cells S. uvarum was investigated. Co-flocculation is a fast process (within 5 minutes), occurs in a broad pH range (3.0-8.0) and requires a small amount of calcium (0.1 mM). Agitation affects yeast aggregation; however, an agitation between 60 rpm and 80 rpm has only a little influence on the co-flocculation process, but agitation between 100 rpm and 140 rpm, co-flocculation reached 91 and 94%, respectively. Flocculent cells of S. uvarum had the ability to sediment non-flocculent cells of S. cerevisiae, which shows the suitability of the co-flocculation process for separation of different kinds of non-flocculent cells.
