Zusammenfassung: | Waste is generated in the form of black liquor during pulp processing. Furthermore, lignin, the main ingredient of black liquor, contains a phenylpropanoid compound with prebiotic and antimicrobial activity. Also, it is a component of lignocellulose that has prebiotic and antimicrobial activity effects due to its indigestible nature and it comprises phenylpropanoid components. Therefore, this study examines and identifies the lignin purification and test results of its prebiotic activity. The technique used to identify lignin fraction is called Thin Layer Chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS) plates. Prebiotic activity tests were performed using the calculation of total bacteria on the growth of Lactobacillus casei. The results showed that the purification process using CHCl3, 3 % MeOH:CHCl3, 20 % MeOH:CHCl3, and MeOH yielded 10.68 %, 6.34 %, 11.38 % 44.85 %, respectively. The 3 % MeOH:CHCl3 fraction contained benzaldehyde, 4- hydroxy-3,5- dimethoxy, 1-methylbutyl hexadecanoate, oleic acid, and di-2-ethylhexyl phthalate. The 3 % MeOH:CHCl3 fractionate with a concentration of 15 % also showed a prebiotic activity for L. casei at 6.1 x 102 colonies/mL.
Tijekom prerade pulpe nastaje otpad u obliku crnog luga. Lignin kao glavni sastojak crnog luga sadržava spoj fenilpropanoid prebiotičkoga i antimikrobnog djelovanja. Također, on je i dio lignoceluloze koja zbog svoje neprobavljivosti ima prebiotičko i antimikrobno djelovanje, a sastoji se od fenilpropanoidnih komponenata. Stoga se u ovom istraživanju ispituju i razmatraju pročišćivanje lignina i rezultati prebiotičke aktivnosti. Za identifikaciju frakcija lignina primijenjene su tankoslojna kromatografija (TLC) i plinska kromatografija s masenom spektrometrijom (GC-MS). Ispitivanje prebiotičke aktivnosti provedeno je korištenjem izračuna ukupnog broja bakterija na rast Lactobacillus casei. Rezultati su pokazali da je proces pročišćivanja uz pomoć CHCl3, 3 % MeOH:CHCl3, 20 % MeOH:CHCl3, i MeOH dao prinos od 10,68 %, 6,34 %, 11,38 % i 44,85 %. Frakcija 3 % MeOH:CHCl3 sadržavala je benzaldehid, 4- hidroksi-3,5-dimetoksi, 1-metilbutil heksadekanoat, oleinsku kiselinu i di-2-etilheksil ftalat. Frakcija 3 % MeOH:CHCl3 koncentracije 15 % također je pokazala prebiotičku aktivnost za L. casei pri 6,1 × 102 kolonija/mL. |
