  • Enzymatic deinking of office-waste paper was studied using crude cellulase and papain-hydrolyzed cellulase from Trichoderma reesei Rut C-30 in small-scale and mid-scale. The results were compared with deinkings using commercial enzyme(Novozym 342) and conventional chemical methods. Maximum brightness and freeness were obtained at 3 units/g Oven Dry Paper(ODP) of CMCase activity using crude cellulase in mid-scale deinking experiments. The deinked pulp had higher physical strength and brightness, and lower freeness and yield than the pulp deinked in small scale. In small scale deinking, maximum brightness and freeness were obtained at 2 unit/g ODP. Deinking by papain-hydrolyzed cellulase showed similar results with one by Novozym 342. It was better in brightness and freeness, but showed lower physical strength and yield, than the conventional deinking by sodium hydroxide. The ratio of endo-1,4-glucanase and exo-1,4-glucanase components in papain hydrolyzed cellulase from T. reesei Rut C-30 was similar to that of commercial enzyme, Novozym 342, implicating a successful application as a deinking enzyme.

  • This study intends to clarify how Sayeok-tang(here in after reffered to SYT) affect C57BL/10 mice whose osteoarthritis was induced by papain. Osteoarthritis was induced by injecting papain in the knee joint of 3 groups(n=6) of mice. Normal group was non-treatment group and was not injected papain, whereas control mice were orally administered with $200{\mu}{\ell}$ of physiological saline. Positive comparison group was medicated with 100 mg/kg of Joins$^{(R)}$ mixed with $200{\mu}{\ell}$ of physiological saline. Experimental group was medicated with 400 mg/kg of SYT mixed with $200{\mu}{\ell}$ of physiological saline. Both Positive and experimental comparison groups were orally medicated once per day for 4 weeks. After the experiment, the functions of liver and kidney, inflammation cytokine values within serum, degree of revelation for inflammation cytokine genes, immune cells within blood, metabolism of arachidonic acid and amount of cartilage were measured and histopathological changes in the knee joint structures were observed. As results, SYT had no significant effect on the liver and kidney functions. Interleukin-$1{\beta}$(IL-$1{\beta}$), interleukin-6(IL-6), monocyte chemo attractant protein-1(MCP-1) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) were significantly decreased. Inflammation cytokines in joints were all significantly decreased. Prostaglandin $E_2(PGE_2)$, thromboxane $B_2(TXB_2)$ were significantly decreased. Destruction of cartilage on micro computed tomography(CT)-arthrography was meaningfully decreased. In terms of histopathology, infiltration of inflammation, proliferation of synovial membrane, subsidence of cartilage and bone due to penetration of excessive formation of synovial cell and destruction of cartilage were small. Based on all results mentioned above, Sayeok-tang(SYT) is believed to be meaningful for suppressing the progress of osteoarthritis and its treatments because of its anti-inflammatory effects and alleviation of pain with histopathological effective efficacy.

  • Objectives : This study was carried out to know the anti-osteroarthritic effects of Bangkibokryeong-tang(Fanjifuling-tang(BBT)) on the papain-induced osteoarthritis C57BL/10 mouse. Methods : Osteoarthritis was induced by injection of papain(6 ${\mu}l$) into knee joint of mouse. Osteoarthritic mice were divided into 4 groups(normal, control, joins(R), BBT). The injection did not fit the normal group. A week later, after the injection of papain, control group was taken normal saline 200 ${\mu}l$, positive control group was taken joins(R)(100 mg/kg), treated group was taken extract of Bangkibokryeong-tang(Fanjifuling-tang(BBT))(400 mg/kg). After then, we examined hepatotoxicity, nephrotoxicity, inflammation cytokines, expression of inflammation factor mRNA, hemotology, histology through the micro CT-arthrography, and etc. Results : 1. Hepatotoxicity and nephrotoxicity have not expressed. 2. The levels of IL-$1{\beta}$, TNF-${\alpha}$, IL-6, MCP-1, Thromboxane B2, Leukotriene B4, Prostaglandin E2 in serum were significantly decreased. 3. In hematology, the levels of neutrophils and monocytes were significantly decreased. 4. The expression of inflammation factor mRNA like TNF-${\alpha}$ and IL-6, COX-2, iNOS-II were significantly inhibited. 5. In micro CT-arthrography, cartilage volume was less decreased. 6. The degree of osteoarthritis induced damage of joint of BBT group is low in histopathologic observation(hematoxylin&eosin(H&E), Safranin-O). Conclusions : According to this study, BBT has effect of anti-osteoarthritis. Further clinical research for the cartilage protective effect is necessary.

  • Papain과 pepsin에 의한 부분 가수분해가 번데기 농축단백질의 기능적 특성에 미치는 영향을 검토하였다. TCA 가용성 질소량을 측정하여 얻은 가수분해 정도는 papain으로 10분과 60분간 처리한 결과 각각 10.23%와 19.17% 였으며 pepsin으로 10분과 60분간 처리한 경우는 각각 15.41%와 21.41%로 나타났다. 효소처리한 번데기 농축단백질의 질소 용해도는 실험한 pH 전범위에서 증가하였으며 특히 papain과 pepsin 모두 60분 처리한것이 10분간 처리한것 보다 높게 나타났다. 0.03M $CaCl_2$를 첨가한 결과 전반적으로 질소 용해도가 증가하는 경향을 나타내었다. 번데기 농축단백질의 겉보기 밀도는 papain으로 처리시 차이가 나타나지 않았으며 pepsin의 겨우는 다소 증가하는 경향이었다. 수분 흡수력의 경우 pepsin으로 10분간처리한것 이외에는 큰차이를 나타내지 않았으나 지방흡수력은 papain과 pepsin으로 부분 가수분해한 결과 전반적으로 증가하였다.

  • 소간추출물은 각종 간질환에 해독효과를 가진 것으로 알려져있다. 항독성 소간추출물의 대량생산 공정을 개발하고자 효소의 선발 및 가수분해의 최적조건을 탐색하였고, 확립된 분해조건으로 항독성 소간추출물의 시제품을 제조하여 일반성분, 미생물, 그리고 비타민 $B_{12}$함량을 분석하였다. Bromelain, papain, ficin, pancreatin, 그리고 protease NP등의 효소 중 추출물의 건물량과아미노태 질소의 수율이 양호하고 경제성이 뛰어난 papain을 최적효소로 선발하였다. Papain(1%)을 소간 분쇄물에 첨가하여 65$^{\circ}C$에서 24시간 동안 가수분해하는 조건을 확립하였다. 분무건조한 항독성 소간추출물의 시제품은 원료 간 대비 11%의 수율을 보였고 건물량은 95%, 총질소 함량은 11.8%이었다. 또한 병원성 미생물은 검출되지 않았고 비타민 $B_{12}$ 함량은 4.1 ${\mu}$g/g이었다. 본 연구에서 확립한 가수분해조건은 높은 수율의 항독성 소간추출물 생산에 적용할 수 있을 것으로 생각한다.

  • 상업적 단백질 분해 효소에 0.02% $CaCl_2$를 첨가하여 응유 활성화를 시킨 탈지유에 대한 분해 작용의 결과를 요약하면 다음과 같다. 다양한 효소별 가수분해 시간에 따른 가수분해도는 미생물 유래 효소와 trypsin은 pepsin과 papain W-40보다 높은 분해도를 나타냈다. 12% TCA 용액에 가용성인 NPN의 양은 trypsin이 가장 높은 분해도를 나타내었고 rennet과 pepsin이 가장 낮은 분해도를 보였다. 전기영동에 있어서 trypsin과 protease S는 $\alpha$- lactalbumin을 분해하였고 papain w-40은 $\beta$- lactoglobulin을 미약하게 분해하였으며 neutrase 1.5는 90분 이후부터 $\alpha$-lactalbumin과 $\beta$-lactoglobulin을 분해하였다. Rennet과 비교한 전기영동상에서는 rennet에 의해 분해 되지 않은 ${\alpha}_s$- casein과 $\beta$-casein을 trypsin과 protease S가 다량 분해하였고 $\kappa$-casein은 rennet에 비해 papain W-40이 상당 수준의 분해상을 나타내었다. 이상의 결과 가수분해도 및 NPN 양은 trypsin, neutrase 1.5 및 protease S가 다른 효소에 비해 높게 나타났으며, 전기영동상에서는 pepsin과 neutrase 1.5가 rennet과 유사한 경향을 나타내었다.

  • 일반적으로 음이온 계면활성제는 효소의 disulfide bond를 분해시켜 효소의 활성이 없어진다. 따라서 특정한 캡슐에 효소를 포집하여 안정도를 증대시킨다. 본 연구에서는 polyethylene glycol (PEG), polypropylene glycol (PPG), 그리고 PEG-PPG-PEG block copolymer 등의 폴리올을 이용하여 papain 효소의 안정도를 증대시켰다. Energy dispersive spectroscopy (EDS)와 confocal laser scanning microscope (CLSM) 분석을 통하여 폴리올은 고분자층과 효소의 중간에 위치하며, 이들은 완충액으로 작용하여 효소의 안정도를 증대시키는 것으로 확인하였다. 또한, 이온 복합체를 이용하여 다층 캡슐을 제조하여 wash-off 형태의 세정제에 응용하였다. 세정제 내에서 계면활성제와 물은 효소캡슐의 표면에 분산되었으며, 캡슐의 중앙부분으로 서서히 침투되었다. 반면에 본 연구에서 사용된 sodium lauroyl sarcosinate와 polyguaternium-6는 물이 효소부분으로 침투하지 않는 것을 in vivo 시험을 통하여 확인하였다.

  • To identify and examine the distribution of proteolytic inhibitory activity in crude extracts from fish eggs, and to determine the applicability of these protease inhibitors as anti-degradation agents in surimi-based products and fish meat, we compared the inhibitory activities of various extracts from fish eggs to those of commercial proteases, such as trypsin and papain. We used the optimal conditions for the screening of trypsin activity: 30 ug/uL of 0.1% trypsin and 0.6 mM Na-benzoyl-L-arginine-p-nitroanilide (BAPNA) with a pH of 8.0 at $40^{\circ}C$ for 60 min. The activities of papain and four commercial proteases were investigated after mixing with 100 ug/uL enzymes and 0.3% casein with a pH of 8.0 at $40^{\circ}C$ for 60 min. We performed a screening assay to detect the inhibitory activity (%) of crude extracts from eight species of fish eggs against the target proteases trypsin and papain. The assay revealed a wide distribution of trypsin and papain inhibitors in fish eggs. The specific inhibitory activities (11.6.28.6 U/mg) of crude extracts from fish eggs against trypsin and BAPNA substrate were higher than that (0.64 U/mg) of egg whites, used as a commercial inhibitor. The inhibitory activities of crude extracts from fish eggs against trypsin, and of egg whites against casein substrate (1.94.4.51 U/mg), were higher than those of papain (0.24.1.57 U/mg) and commercial protease (0.04.0.32 U/mg). The extracts from fish eggs were rich in protease inhibitors that exhibited strong inhibitory activity against trypsin, a serine protease, and papain, a cysteine protease.

  • We investigated the production of chitin oligosaccharides using food grade papain. A solution of commercial food grade papain (FGP) was dialyzed for 12 h before measuring its chitinolytic activity. The effects of enzyme concentration, reaction temperature, and pH on the endochitinase and $\beta$-N-acetylglucosaminidase activities and the thermostability of these enzymes were investigated. In adddition, the reaction products were analyzed with gel filtration on a Bio-Gel P2. The endochitinase activity was twentyfold higher than that of $\beta$-N-acetylglucosaminidase. The optimal endochitinase activity was at pH 3.0, while the maximal $\beta$-N-acetylglucosaminidase activity was at pH 6.0. The reaction product consisted mainly of the dimer of N -acetylglucosamine, with a small amount of its trimer. Under the experimental conditions, $120{\mu}g$ of chitin oligomers were obtained with 1 mg of FGP protein after an incubation of 2 h.
