Tencel is a high quality cellulosic fiber, which is controlled and processed by an environmentally sound route. But, the point about tencel and the reason why it achieves its unique touch in its finished state is that it is a fibrillating fiber. That means it can take a great deal of punishment during the finishing process, which raise the fiber to produce the characteristics handle, without destroying the cloth. The aim of cellulase treatment is to improve appearence of tencel, plus the fiber ends protruding from the fabric surface. But enzymatic hydrolysis can weakens the fiber ends and changes the properties of fabrics. This study examined about the changes of properties according to several conditions and effect of cellulase to fibril of tencel. The results are as follows. The weight loss was occurred, tensile strength was decreased, softness was increased. And cellulase treatment reduced amount of fibril.

Five kinds of commercial ramie and hemp fabrics were treated with cellulase under different concentrations. Samples were mercerized before enzyme treatment to investigate the effect of mercerization on cellulase enzyme treatment. Physical characteristics(weight loss, tear strength retention, wrinkle recovery, drape stiffness, dyeability) of cellulase enzyme treated and untreated samples were measured and compared. X-ray diffractions were examined to verify if there were any changes in their crystallinity of enzyme treated fabrics. Weight loss, wrinkle recovery and degree of crystallinity increased as the concentration of cellulase enzyme increased. In the meanwhile, tear strength retention and drape stiffness and dyeability decreased. Enzyme activity was more effective on mercerized samples. Particularly, there was distinct tendency to increase weight loss and flexibility.

In this study, acid cellulase was used to treat denim fabrics by varying pH, temperature, enzyme concentration, treatment time and non-ionic surfactant (Triton X-100) concentration. Treatment condition was controlled based on the weight loss. The characteristics of enzyme-treated fabrics were measured in terms of tearing strength, stiffness, and color difference. The optimum conditions for cellulase treatment of denim fabric were pH 5.0, $50^{\circ}C$, 3% (o.w.f.), 90minutes. The weight loss did not change significantly with the addition of a non-ionic surfactant, but it improved when more non-ionic surfactant were used. The tearing strength of enzyme-treated denim fabrics did not deteriorate. The stiffness of the treated fabrics improved with the enzymatic treatment with and without the non-ionic surfactant. The difference in color of fabrics treated with enzyme increased.

In this study we evaluated the method to develop red ginseng oil containing high content of phytochemicals by enzymes treatment. To select the optimum extraction process of red ginseng with oils, the antioxidant activities of red ginseng using various enzymes were measured. Red ginseng after 0.5% cellulase treatment for 1 hr at $50^{\circ}C$ had higher antioxidant activity than the other conditions. We found that red ginseng/soybean oil extracted for 15 days at $40^{\circ}C$ after 0.5% cellulase treatment increased DPPH radical scavenger activity and decreased the TBA and POV values. However, red ginseng/olive oil had little functional activities compare to the red ginseng/soybean 0il. We also analyzed vitamin A and E by HPLC and found that vitamin E was increased by 0.5% cellulase treatment in the oil. This is the first report that red ginseng oil extracted by enzyme treatment has various beneficial effects.

Biopolishing using cellulases was introduced in the production of cotton fabric in order to improve the quality of fabric environmental friendly and is commonly used in the textile industry. In this study, the application of a crude cellulase from Acanthophysium sp. KMF001, which was excellent for the saccharification of cellulose, on biopolishing was evaluated. The optimum treatment biopolishing condition was at $50^{\circ}C$ and pH 4.5 for 60 minutes with 10% crude cellulase of fabric weight. After the optimized biopolishing, the crude cellulase of Acanthophysium sp. KMF001 reduced the tensile strength of the tested cotton fabric less than a commercial cellulase. The appearance of the cotton fabric after the treatment of the crude cellulase of Acanthophysium sp. KMF001 was similar to the fabric after a commercial cellulase treatment. All these results support that the crude cellulase of Acanthophysium sp. KMF001 was a good biopolishing cellulase.

Recently, eco-friendly processing has been focused in the textile industry in order to reduce environmental pollutions. Applications of enzyme technology to the textile industry are an example of more environmentally compatible processes. However, there is not enough quantity of referring to denim fabric subjected to enzymatic treatment. In this study, depending on pH, temperature, cellulase concentration, and treatment time, the weight loss of denim fabrics was examined. Characteristics of enzyme-treated fabrics were measured by tearing strength, stiffness, and K/S values. The effect of a non-ionic surfactant (Triton X-100) on characteristics of the enzyme-treated fabrics was evaluated. The cellulase treatment condition on the cotton fabric were optimized to pH 6.0, $50^{\circ}C$, 1%(o.w.f.), and 60minutes. Characteristics of denim fabrics by cellulase treatment in the presence of Triton X-100 did not improve because Triton-X inhibited the activity of enzyme.

The effects of soymilk residues solubilization by cellulase, protease, koji and yeast were investigated on dry matter and protein yields, amino acid and organic acid contents. Co-treatment of soymilk residues by cellulase and protease gave high dry matter yield and protein yield. Koji treatment followed by yeast fermentation was effective for increasing organic acid content and producing soy sauce-like taste and odor. Organic acid content of fermented hydrolysates was improved by cellulase treatment. Protease treatment rather than koji treatment gave high amino acid content, and cellulase treatment seemed to have little effect on increasing free amino acid content. In sensory evaluation, koji-treated hydrolysate showed higher overall acceptance than other hydrolysates, however it showed lower overall acceptance than commercial fermented soy sauce.

In this study, we tried to establish the best method for fresh blueberry beverage production using enzyme treatment as well as low temperature extraction. During extraction of physiologically functional materials, we used low temperature to prevent nutritional loss by heat. In addition, we investigated optimal blueberry extraction conditions using various enzyme treatments (cellulase, pectinase, cellulase:pectinase (1:1) mixture) to increase extraction efficiency and reduce turbidity. A variety and ratio of enzymes, extraction temperature, extraction time, and shaking speed were considered for the best extraction efficiency rate. We observed high extraction efficiency rates of 85.72-86.55% and 87.06-87.93%, respectively, upon cellulase or pectinase treatment. In addition, a mixture of cellulase:pectinase (1:1) showed an extraction efficiency rate of 86.84-88.14%. The best extraction efficiency rate was observed when crude blueberry was treated at $45^{\circ}C$ (87.91%), for 3 h (87.88%), in a 90 rpm shaker (89.19%). Sugar content and acidity of blueberry extract were not affected by the various treatments. However, total phenolic compounds were detected upon pectinase treatment (18.62 mg/g). Only fructose and glucose as free sugars were found in all samples regardless of treatments and extraction conditions.

This study has examined weight loss rates of Iyoceu, lyocell/cotton, cotton that were treated with cellulase under different concentration, time, temperature and pH. and compared physical properties changes of tensile strength, drape, moisture absorbency, shrinkage and dyeability. The notable results are summarized as follows: Lyocell was in need of pretreatment by NaOH in the side of weight loss, tensile strength and dyeability. Weight loss rates of cellulose fabrics by cellulase treatment were in the order of cotton > lyocell/cotton > lyocell at the same conditions. In case of lyocell and lyocell/cotton, weight loss rates showed up lower than cotton, while strength retention decreased, drape and strength flexibility were highly improved after cellulase treatment.

This experiment was conducted to study the effects of lactic acid bacteria (LAB) inoculation either alone or in combination with cell wall degrading enzymes on the fermentation characteristics and chemical compositions of Rhodesgrass silage. Over to 1 kg of fresh Rhodesgrass sample a treatment of inoculant LAB with or without addition of an enzyme of Acremoniumcellulase (A) or Meicelase (M) or a mixture of both enzymes (AM) was applied. The treatments were control untreated, LAB-treated (application rate $1.0{\times}10^5cfu/g$ fresh sample), LAB+A 0.005%, LAB+A 0.01%, LAB+A 0.02%, LAB+M 0.005%, LAB+M 0.01%, LAB+M 0.02 %, LAB+AM 0.005%, LAB+AM 0.01%, and LAB+AM 0.02%. The sample was ensiled into 2-L vinyl bottle silo, with 9 silages of each treatment were made. Three silages of each treatment were incubated at 20, 30 and $40^{\circ}C$ for 2-months of storage period. All silages were well preserved with their fermentation quality has low pH values (3.91-4.26) and high lactic acid concentrations (4.11-9.89 %DM). No differences were found in fermentation quality and chemical composition of the control untreated silage as compared to the LAB-treated silage. Combined treatment of LAB+cellulases improved the fermentation quality of silages measured in terms of lower (p < 0.01) pH values and higher (p < 0.05) lactic concentrations than those of LAB-treated silages. Increasing amount of cellulase addition resulted in decrease (p < 0.05) of pH value and increase (p < 0.05) of lactic acid concentration. LAB + cellulase treatments (all cellulase types) reduced (p < 0.01) NDF, ADF and in vitro dry matter digestibility of silages compared with the control untreated silages. The fermentation quality and the rate of cell wall reduction were higher (p < 0.01) in the silages treated with LAB + cellulase A than in the silages treated with either LAB+cellulase M or LAB + cellulase AM. Incubation temperature of $40^{\circ}C$ was likely to be more appropriate environment for stimulating the fermentation of Rhodesgrass silages than those of 20 and $30^{\circ}C$.
