  • The two parts of chestnut peels, outer and inner layers, were collected and investigated for cultivation of various mushrooms, i.e., Pleurotus ostreatus, Lentinus edodes, Hericium ramosum and the others. The inner layer of chestnut peels was contaminated with the mycelia of the blue fungi when collected, consisted of 17~20 % holocellulose, being a good material for growths of the above fungi. The outer layer was considered to be poor materials for fungal growth, because of lower amounts of minerals. Both mushrooms of Pleurotus ostreatus and Hericium ramosum grow well, and were produced fruiting bodies on the solid media containing only inner layers of chestnut peels. The Imhyup No.6 and Imhyup No.7 varieties of Lentinus edodes grow well, but produced few fruiting bodies in the solid media containing only inner layers of chestnut peels. The growth patterns of P. ostreatus and L. edodes were evaluated by production of $CO_2$. and considered to be different according to fungi. The inner layers of chestnut peels as agricultural by-products were considered to be a good material for mushroom cultivation, and outer layers could be used as being added with the other additives. The chestnut peels, being the environmental pollutants in rural areas, was considered to be a good substrate for mushroom cultivation.

  • This study was conducted to make on-site survey on the output pattern and utilization situation of 19 by-products selected, to evaluate their nutritional characteristics, to find out a reliable index with which digestion of by-products can be predicted on the basis of chemical compositions analyzed and to diagnose the risk of using book values in the absence of the actual values analyzed for diet formulation. Production and utilization situations of by-products were quite various. Nutritionally, fruit processing by-products such as apple pomace (AP), pear pomace (PP), grape pomace (GP), and persimmon peel (PSP), and bakery by-products (BB) were classified as energy feeds. Soybean curd meal (SCM), animal by- products such as blood (BD), feather meal (FM) and poultry by-products (PB), and activated milk processing sludge (AMS) were classified as protein feeds. Soy hulls (SH), spent mushroom compost (SMC), barley malt hulls (BMH), waste paper (WP) and broiler litter (BL) were classified as roughage. Rumen contents (RC) and restaurant food waste (FW) were nutritionally analogous to complete diets for cattle and swine, respectively. Compared to soybean meal (SBM), BD and FM contained high (P<0.05) levels of amino acids and barley malt sprouts (BMS), AMS and FW contained low (P<0.05) levels of amino acids. Enzymatic (pepsin) digestibilities of proteinaceous feeds ranged between 99 and 66%. In vitro DM digestibility was high (P<0.05) in the order of FW, BB, AP, SH, PP, PSP, BMH, BMS, SCM, GP, RC, PB, BL, WP, SMC, AMS, FM and BD. In vitro DM digestibility had the highest correlation (r=0.68) with nonfibrous carbohydrate among chemical components. Differences between analyzed values of chemical components and book values were considerable. Caution is required in using book values when large amount of by-products are used in diets.

  • For artificial cultivation of Phellinus baumii, we have conducted a study on cultural characteristics and condition of fruitbody formation in sawdust cultivation. Mycelial density and incubation rate were higher in oak sawdust+rice bran (4 : 1) medium than oak sawdust 100% medium. However, primordia and fruitbody formation were higher in oak sawdust 100% medium than rice bran added medium. Bigger bottle capacity (1,100 ml) resulted in a little higher yield and more biological efficiency than 850 ml bottle.

  • Spent mushroom substrates (SMS) is a by-product remaining after a crop of mushrooms. About four surfactin-producing strains were isolated from SMS (Pleurotus eryngii). Among of them, one isolate, which designated to YJ07, potentially showed the antifungal activity against Aspergillus flavus and Aspergillus ochraceous producing mycotoxin on PDA medium. The biochemical characteristics of the strain YJ07 was similar with Bacillus subtilis and Bacillus amyloliquefaciens by Bacillus ID kit and VITEK 2 system. Comparative 16S rDNA gene sequence analysis of the strain YJ07 also showed that the strain YJ07 was most closely related to Bacillus amyloliquefaciens with sequence similarity of 99.5%. On the basis of their biochemical characteristics and phylogenetic distinctiveness, the strain YJ07 was classified within the genus Bacillus as Bacillus amyloliquefaciens YJ07. The antifungal compound from B. amyloliquefaciens YJ07 was similar to lipopeptide surfactin from Bacillus subtilis by TLC and HPLC analysis.

  • This study was carried out to investigate the suitability of various agricultural by-products as basal substrates for the mycelial growth and fruiting body formation of Hericium erinaceum. For this aim, oak sawdust, cotton waste, sugarcane bagasse, Job's tears, rice hull, Chinese cabbage, and coconut waste were used as sole or mixed substrate(s). Corn waste and rice bran were used as nutrient supplements. The growth and density of mycelium, yield of fruiting body, and biological efficiency were compared among tested substrates colonized by Hericium erinaceum. The best measurement of mycelial growth and density, yield of fruiting body, and biological efficiency in a laboratory test was found in a spawn substrate composed with oak sawdust 80% and rice bran 20%. The suitability of this spawn substrate composition for Hericium fruiting body production was testified through practical tests in plastic bottles (850 ml) in a mushroom farm which had bottle cultivation facility. However, test in a mushroom farm which had plastic bag cultivation facility, best production of Hericium fruiting body (520 g per one bag) was observed in a spawn substrate composed of cotton waste 40%, saw dust 40%, corn waste 10%, and rice bran 10%.

  • Physicochemical characteristics and antioxidative activity were measured to investigate the possibility for functional characteristics of Pleurotus eryngii and its by-products. By-products of Pleurotus eryngii were classified with mushroom, fungal body and fermented mushroom by-product. Moisture was the highest in fermented mushroom by-product and crude protein was 1.72%, in mushroom. Crude fiber content was less than 10% except the fungal body by-product. Mineral content appeared to be the highest in the fermented mushrooom with a value of 3,696.1 mg/100 g, and potassium was a predominant mineral in Pleurotus eryngii as well as its by-products. Amino acid content was the highest in mushroom with a level of 989.59 mg/100 g. DPPH radical scavenging ability of the fermented mushroom was the highest, and its methanol extract and water extract exhibited $64.07{\pm}0.23%$ and $76.27{\pm}1.46%$ of scavenging activity at a concentration of 10 mg/ml. Reducing power was significantly higher in the fermented mushroom in comparison with those of the mushroom, mushroom by-product, and fungal body by-product. The reducing power of the water extract of fermented mushroom was the highest with a value of $2.22{\pm}0.03$. SOD-like activities for the individual samples except the fungal body by-product were higher than 50% at a concentration of 10 mg/ml. The hydroxyl radical scavenging abilities of the individual samples except the fungal body by-product were over 50%. Nitrite scavenging effects were better in pH 2.5 than in pH 4.0. While the nitrite scavenging effects of methanol extracts were $42.93{\pm}1.71{\sim}72.97{\pm}2.18%$, those of the water extracts were $57.66{\pm}1.80{\sim}81.07{\pm}0.81%$. Antioxidative activity of the fermented mushroom appeared to be the highest among the mushroom by-products. Taken together, these results provide an insight into utilization of the mushroom by-products as materials for functional foods and animal feed.

  • This study was conducted to survey and analyze the quantity of various organic wastes and to vitalize the utilization of agri-food by-products as raw materials for Total mixed ration (TMR), to improve feed cost savings and the quality of animal products. On-the-spot obstacles for animal farmers, along with legal and institutional alternatives are presented. The results are as follows. First, organic wastes in Korea are managed by the Allbaro system created in the Wastes Control Act, which processes 10,488 tons of cooking oil waste, 832,493 tons of animal and plant residues, 5,740 tons of animal carcasses, 1,171,892 tons of animal residues, and 2,172,415 tons of plant residues including 12,905 tons of rice hull and bran, for a total of 4,205,931 tons. Raw materials for TMR, namely rice hulls and bran as well as plant residues, accounted for 51.7% of the total national organic waste. The top 10 municipalities process 76~100% of all organic wastes and a supply management system is needed for the waste. Second, the 10 major agri-food by-products used as raw materials for TMR are bean curd by-product, rice bran, oil-cake, brewers dried grain, Distiller's Dried Grains with Solubles (DDGS), barley bran, soy sauce by-product, citrus fruit by-product, mushroom by-product and other food by-product (bread, noodles, snacks, etc.). Third, the biggest difficulties in using agri-food by-products are legal obstacles. Because agri-food by-products are regulated as industrial wastes by the Waste Control Act, animal farmers that wish to use them have legal reporting obligations including the installation of recycling facilities. To enable the use of agri-food by-products as raw materials for TMR, waste management system improvements such as 'the end of waste status' and the establishment of more than 10 public distribution centers nationwide are deemed essential.
