In order to produce cellulosic single cell protein from the cellulosic wastes, 252 strains of cellulose assimilating bacteria were isolated front 225 sources of microorganisms such as decomposed wood, compost soils, soils, cotton fabrics and useless paper. The isolates were investigated for their ability to utilize cellulose as carbon source. One of them was screened by its stong cellulose assimilating abililty, and was identified as Cellulomonas flavigena.

Cellulose-degrading bacteria were isolated and identified from cocopeat which has a good quality as a bulking agent in composting. Various bacteria from different sourecs of cocopeat were detected on CMC agar media, and these were found to be Burkholderi2a sp., Bacillu subtilis, Sphingomonas sp., Rhodotorula sp. & Pseudomonas sp. etc. Among these, four bacteria were further selected and analyzed for their biochemical characteristics and CMCase activities. CMCase activities of four bacteria, P. aeruginosa, P. stutzeri, B. subtilis, and P. luteola were found to be 83%, 40%, 8%, 6%, respectively, compared with that of the standard strain Cellulomonas sp.

Samsebul, the altar portrait behind the statue of Buddha in the main building of Bonghwang temple in Andong, has been designated as Tangible Cultural Property No. 406. These alter portraits have significance as the standard of the research of Samsebul in Joseon period. In this study, fibre of the ground textile is identified using microscopic examination, solubility test, ATR-FT-IR, SEM, XRD. Two samples from Yaksabul(A, B), one sample from Seokgabul(C), and one sample from Amitabul(D), which were collected during the conservation process, were prepared for this study. In previous record, above samples were documented as hemp. Due to severe deterioration and accumulated dust layers on these samples, it was hard to recognize them with naked eyes, but through this study, we could identify that all samples except one from Yaksabul(A) are silk.

Microorganisms which can degrade organic compounds such as proteins, lipids, and cellulose in food wastewater, were isolated from food wastewater, livestock wastewater, earthworm, and etc. Among these, eleven strains which showed higher degrading activities against three organic compounds, were finally isolated, characterized, and identified. Nine strains were found to be Bacillus species, and other two were to be Enterobacter sp. and Pantoea agglomerans. The strains FWB-5 (Bacillus pumilus), FWB-6 (B. lichenisformis) and OD-4 (Pantoea agglomerans), isolated from food wastewater and livestock wastewater, respectively, showed higher three enzyme activities to organic compounds, especially to cellulose, compared to other strains. The optimal growth conditions for the great enzyme activities were at $37^{\circ}C$ with pH 7.0 for FWB-5 and OD-4 strains, whereas, these were at $25^{\circ}C$ with pH 7.0 for FWB-6 strain.

The aim of this study was to obtain information about two early-20th Century clothes, for which the "National Memorial Museum of Forced Mobilization under Japanese Occupation" has sought to receive preservation treatment. Optical microscopes and a scanning electron microscope were used to investigate the weaving of the clothes, and Fourier transform infrared spectroscopy(FT-IR) was used to investigate the fibers. Cloth A is believed to be a Japanese half sleeved inner wear(Hanjuban) used by women. Cloth B is believed to be working clothing that was checked by an Osaka plant. This was verified by a book written by the Japanese army. Both of the clothes were made mostly from cotton, although the inner wear also used viscose rayon on the neck collar. The button on the working wear was made of urea formaldehyde resin, an early precursor to plastic.

Cellulase producing microorganisms, GPC-1, GPC-2, GNR-1 GNR-2, and GNR-3, were screened from the Rumen fluid of Korean Native Cattle. Isolated GPC-1 and GPC-2 were identified as Ruminococcus sp. according to results of the Gram stain and anaerobic characteristics. Based on morphological and physicochemical identification, the isolate GPC-1 and GPC-2 were identified as strains of Ruminococcus albus and Ruminococcus flavefaciens, respectively. Isolated GNR-1 GNR-2 and GNR-3 were identified as Bacteroides sp., Butyrivibrio sp. and Clostridium sp. according to results of the Gram stain, $H_2S$ producition and spore formation, respectively. Based on morphological and physicochemical identification, the isolate GNR-1 GNR-2 and GNR-3 were identified as strains of Bacteroides succinogenes, Butyrivibrio fibrisolvens and Clostridium cellobioparum, respectively.

For the purpose of producing cellulosic single-cell protein from the agricultural wastes, 172 strains of cellulose-assimilating bacteria were isolated from 102 samples of rotten woods, compost soils, soils and so on by the enrichment culture technique. The isolates were examined for their ability to utilize cellulose as carbon source, and then six strains were screened by their strong cellulose assimilating ability and identified as follows: 1. Among six strains of bacteria screened, five strains were identified as species belonged to the genus Cellulomonas and the remainder to the genus of Sporocytophaga. 2. The isolated Sporocytophaga species was identified as S. ellipsosporn because it has a ellipsoidal microcyst. 3. The isolated Cellulomonas species were identical to a strain of C. fimi, C. aurcgena, C. gelida, respectively and two strains to C. flavigena. 4. The isolated C. aurogena was proved to be a new variety becauuse it has different characteristics of assimilating pentoses such as arabinose and xylose from the strain discribed in Bergey's Manual.

Twenty-one strains isolated, cellulose decomposing fungi, were identified on the basis of morphological, physiological and biochemical properties as Acremonium sp., Aspergillus sp., Chaetomium sp., Chrysonilla sp., Doratomyces sp., Fusarium sp., Gliomastix sp., Penicillium sp., Trichoderma sp., Varicosporium sp. and Verticillium sp.. The optimum tempeture for growth was in the range of $20-30^{\circ}C$. Most of the isolated stains utilized all tested carbon sources, and scarcely utilized urea as a nitrogen source. Only the strain No.2 had high activity of cellulase.
