  • 효과적인 응유효소 생산을 위해 응유효소 생산 균주로 선정된 Mucor mucedo C-7을 밀기울 고체배지에 배양하여 최적 배양 조건을 검토하였다. 그 결과 밀기울에 대한 첨수량은 밀기울량에 100% 첨수하였을때 효소 생산이 가장 양호하였으며 배양 은도와 시간은 각각 3$0^{\circ}C$, 72시간이 가장 적당함을 알 수 있었다. 또 밀기울 배지에 증류수 대신 Macllvaine 완충용액 (pH4.5)을 첨가 하였을 경우 효소 생산은 현저히 증가하였으며 응유효소의 활성도 중류수를 첨수한 경우 보다 안정함을 알 수 있었다.

  • 대용응유효소를 생산하는 균주를 선별하기 위해 토양, 건초, 퇴비 등 114시료를 분리원으로 하여 응유효소를 생산하는 16균주를 분리하였으며 이들 각 균주들이 생산하는 유응고력과 단백질 분해력의 비는 균주번호 C-7 것이 1,929로 가장 좋았다. C-7 균주의 균사는 회백색으로 격막이 없었고 포자낭병은 균사로부터 단독으로 곧게 뻗어 갈라지지 않은 monomucor형으로 그 끝은 구형의 포자낭을 형성하였으며 적합한 생육온도와 생육 pH의 범위는 20-$30^{\circ}C$, pH 3.0-8.0이었다. 형태적, 생리적 여러 특성에 따라 C-7 균주는 Mucor mucedo로 동정되었다.

  • Habitative microorganisms were isolated from the floated air and surface of record materials of library with ancient archives. The major ecological fungi from them were isolated and identified as Aspergillus niger, Aspergillus oryzae, Neurospora sitophile, Mucor mucedo, Mucor rouxii, Penicilliun notatum, Rhizopus delema, Rhizopus nigricans, Thamnidium elegans, and Tricoderma viridae. When the cellulase activity of fungi isolated from ancient archives and documents was analyzed, Mucor rouxii and Penicilliun notatum showed the highest avicelase and filter paper activity, to 18.089 and 2.819 units, respectively, showing destructive ability of old archives and documents. Whereas, Mucor mucedo revealed the highest CMCase activity of exoglucanase to 7.044 units.

  • In recent years, immobilization agents were introduced into organic contaminated soil remediation and more and more materials were screened and used as the immobilizing carrier. However, effect of the decomposition of the immobilizing carrier on the bioremediation was rarely concerned. Therefore, the decomposition experiment of immobilizing carrier -corncob was carried out in the lab with the efficient degradation fungi - Mucor mucedo (MU) existing, and polycyclic aromatic hydrocarbons (PAHs) residues E4/E6 of the dissolved organic matter and microbial diversity during the decomposition process were studied. The results showed that: a) during the decomposition, the degradation of pyrene (Pyr) was mainly in the first 28 d in which the content of extractable Pyr decreased rapidly and the highest decrease was in the treatment with only MU added. b) Anslysis of E4/E6 changes showed that rich microorganisms could promote aromatization and condensation of humus. c) From the diversity index analysis it can also be seen that there is no significant difference in effects of PAHs on the uniformity of microorganisms. These results will not only be useful to have a better understanding of the bioavailability of contaminants adsorbed to biodegradable carriers in PAHs contaminated soil remediation, but also be helpful to perfect the principle of immobilized microbial technique.

  • The microbiodeterioration of paper material like books, archival material, manuscripts both illustrated and written, decorative wall papers, etc. is a serious problem throughout the world in museums, libraries, archives, etc. where these materials are placed. The major ecological fungi from record materials of library with ancient achieves were isolated and identified as Aspergillus niger, Aspergillus oryzae, Neurospora sitophile. Mucor mucedo, Mucor rouxii, Penicillium notatum, Rhizopus delema, Rhizopus nigracans, Thanmnidium elegans, Tricodema viridae, Bacillus cereus. Bacillus megaterium, Enterrobacter aerogenes, and Staphylococcus auerus. This study was carried out to investigate the antigungal activities of essential oils. The Essential oils from herb were obtained by vapor distillation method, and the antimicrobial activities were examined with ten fungi & four bacteria. It was found to have activity against microorganisms isolated from a achieves stack rooms.

  • Nowadays, the damages caused by molds in cotton textile goods becomes influential. In our country, however, the relations between cotton goods and molds are not investigated and studied in detail. Two hundred and fifty seven kind of mold's samples were collected in ninety places through the whole country. The molds samples are mainly gathered according to each regions and seasons from molded cotton textiles. Out of this samples, we isolated six hundred and seventy two strains of molds and the results of isolation are following. 1. The distributed molds were Aspergillus sp., Rhizopus sp., Penicillium sp., etc. among them Aspergillus sp. were most widely distributed, and next were Rhizopus sp., Penicillium sp. etc. 2. The distribution of Aspergillus sp. abounded peculiarly in the dry season, while Rhizopus sp. in the rainy season. 3. The C.M.C, descomposing enzymes forming activity on molds were greatly concerned with intensity damage of cotton textile goods. 4. The formation of C.M.C. decomposing enzyme was only influenced by physiology of each strains. 5. Regarding to the growth. a. The molds which were saprophyting on the cotton textile goods were indicated vigorous growing. b. Among isolated six hundred and seventy two strains, there were above a hundred strains which produced pigment and nearly half of them fifty nine strains were Aspergillus sp. 6. Twenty one strains in isolated six hundred and seventy two strains were indentified which can heavily damage upon cotton textile. As a results of indentification of the selected strains, the following species was abtained, Aspergillus sydowi, wentii, niger, luchuensis, flavus, fumigatus, nidulans, Penicillium frequentants, roqueforti, chrysogenum, albicans, Rhizopus oligosporus, delemar, Mucor rouxii, mucedo, Neurospora sitophila, Monilia variabilis, fructigena, Cladsporium hurbarum and Aspergillus spp. Mucor spp.
