큰느타리버섯의 병재배 시에 생산 단가의 절감과 배지 다양화의 측면에서 대용할 수 있는 재료를 탐색하고 균사 생장률을 높일 수 있는 배지 조성을 찾기 위하여 본 실험에서는 주재료(톱밥 수종), 첨가재료, 무기염류, 활성물질을 대체 첨가하여 큰느타리버섯의 균사 생장률을 비교하였다. 기본배지의 건비지를 대신하여서 감자전분, 야자박, 단백피 탈지대두분, 면실피, 계분을 비율을 조정하여 사용할 수 있음을 확인하였고 특히, 탈지대두분 2~8% 첨가와 계분의 2% 첨가는 기본배지보다 균사생장에 효과적임을 확인하였다. 또한 기본배지의 미송톱밥에 대해 활엽수 톱밥을 대용할 수 있는 것으로 확인하였고 25.2%로 혼합할 때 가장 효과적이었다. 무기염류 실험에서는 $CaCO_3$, 2~3%, $K_2CO_3$, 0.2%, $MgSO_4{\cdot}7H_2O$ 0.1%, $MnSO_4{\cdot}5H_2O$ 0.05%의 농도로 첨가하였을 때 균사생장에 효과적이었다. 활성 물질들은 그 비용에 대한 충분한 효과를 볼 수 없었다.

The seed, or grain, of modern cultivars of Lupinus angustifolius, commonly known as Australian sweet lupins (ASL), is an established feed resource for the intensive animal industries of Australia, Japan, Korea and several other countries in Asia and Europe. Since the introduction of ASL to the world marketplace about 25 years ago, researchers in many countries have found them to be a valuable component of the diet of beef and dairy cattle, sheep, pigs, poultry, finfish and crustaceans. The seed of ASL contains ~32% crude protein (CP) (~35% DM basis) and 5% oil. The main storage carbohydrates in the seed are the ${\beta}$-galactans that comprise most of the cell-wall material of the kernel and the cellulose and hemicellulose of the thick seed coats. ASL seeds contain about 40% non-starch polysaccharides (NSP) and a negligible amount of starch. This makes them an excellent ingredient for ruminant diets, as the risk of acidosis is very low. The seed of modern cultivars of domesticated Lupinus species contain negligible amounts of lectins and trypsin inhibitors so they do not require preheating before being used as an ingredient in feeds for monogastric species. They have a high digestibility coefficient for protein, >90% for most species, but a low energy digestibility, ~60%, which is mostly due to the high content of NSP. The low content of methionine (0.22%) and of lysine (1.46%) is typical of the legumes. The lysine availability for pigs is >70%. Lupin kernels contain ~39% CP (~42% DM basis), 6% oil and 30% NSP. They have a higher digestible energy for pigs and finfish and a higher metabolisable energy for poultry than whole seed. Commercial operations rarely achieve complete separation of kernel from hull and it is more likely that the kernel fraction, called splits or meats, will contain ~36% CP. The replacement of soybean meal or peas with ASL in cereal-based diets for most intensively reared animals, birds and fish is possible provided lysine, methionine and digestible energy levels are kept constant. This makes ASL economically competitive in many, but not all, circumstances.

왕겨가 Agaricus blazei Murill (AB: 신령버섯)균사체 액체배양 추출물의 항암성을 증가시키는지에 관한 연구를 수행하였다. AB균사체를 대두박을 기본으로 한 액체배지에 다양한 조건으로 배양하여, $\beta$-glucan 함량, Brix, 균사체를 측정하여 적정 생육조건을 선정하고, 이들의 열수추출물의 S-180 cell로 유도한 mouse 복수암에 대한 항암성을 조사하였다. AB균사체는 $25^{\circ}C$에서 5일간 배양하였을 때 최적 생육을 나타내었고, 이 배양물이 다른 조건에서 배양한 배양물보다 우수한 항암성을 나타내었다. AB균사체의 생육 및 항암성은 변온배양에 따른 효과는 없었다. 따라서 이 최적배양조건($25^{\circ}C$, 5일 배양)에서 AB균사체를 1% 왕겨분말이 함유된 액체배지에 배양하고, 이의 열수 추출물의 항암성을 검증하였다. 1% 왕겨가 함유된 액체배지에서 배양한 열수추출물의 항암성은 왕겨가 함유되지 않은 배지의 열수추출물보다 항암성이 유의성 있게 증가되었다(p<0.05). 왕겨의 첨가는 AB균사체의 생육을 오히려 촉진시켰다. 이 결과는 왕겨가 AB균사체 뿐 만 아니라 다른 버섯균사체 액체배양물의 항암성 증진을 위한 원료로 활용될 수 있을 것임을 의미한다.

Present study was undertaken in order to evaluate the lead contents of various feedstuffs produced in Korea and the effect of the burning of gasoline by automobiles on the lead contents. Ninety-one samples near and 95 far road were collected from 9 regions(Do). All of the samples were washed, dry-ashed and analyzed for lead content using atomic absorption spectrophotometer. The mean values obtained were checked for significance of difference using computer. The results obtained were summerized as follows: 1. The lead content in ${\mu}g/g$ of agriculture-byproducts were measured with the following mean values and ranges(in parentheses). Rice bran: $2.07{\pm}1.67$ (0-5.00), rice hull $1.84{\pm}1.18$ (0-3.71), rice straw, $1.27{\pm}1.09$ (0-3.62), soybean pod:$4.55{\pm}3.13$ ($1.13{\pm}10.43$), and wheat bran: $1.69{\pm}0.86$ (0-3.65). 2. The lead content in ${\mu}g/g$ of pasture plants were measured with the following mean values and ranges. Kudzu:$2.71{\pm}1.74$ ($0.38{\pm}8.75$), leed: $2.03{\pm}1.61$ (0-4.54), lespedeza:$4.73{\pm}5.93$ (0-31.25), sagebrush: $4.08{\pm}3.75$ (0-12.18), Korean-grass: $2.11{\pm}1.38$ (0-5.50), maizestalk: $2.62{\pm}2.35$ (0-8.65), clover: $3.83{\pm}2.97$ (0-12.19), alfalfa: $7.14{\pm}0.97$ (4.46-9.25), and timothy: $5.86{\pm}4.79$ (0-9.25). 3. Fourteen samples (22.2%) out of 63 agriculture-byproduct samples and 42 (34.2%) out of 123 pasture plant samples showed lead content of more than $3{\mu}g/g$ which are said to be the upper limit value for cattle. 4. No significant difference between the mean lead contents of near road, and those of far road was recorgnized. 5. The regional mean values for all kinds of samples collected in Kyungbuk and Kyungnam were significantly (p<0.05, p<0.10) higher compared to those in Chungnam and Jejudo.6. From these results it may be concluded that the burning of gasoline by automobiler did not affect on the lead contentes of washed feedstuffs produced in Korea at present.
