During the Japanese colonial period, Japanese brewing companies established 2 breweries in Korea, and brought in malting barley seeds, began trial cultivation in near Daejeon area and Jeju Island, and cultivated hops in Hyesan, Hamgyeong-do. In 1933, Chosun Brewery Co. Ltd. and Showa-Kirin Brewery Co. were established in Yeongdeungpo by Japan and these 2 breweries became the birthplace of today's Hite Brewery and Oriental Brewery. Oriental Brewery tried to cultivate hops and malting barley in Korea, and once self-sufficient but now hops depend on imports, and production of domestic malting barley is about 5% of demand. Beer was only about 5% of domestic alcohol consumption in the early 1970s, but now occupies more than 50% and became the most popular alcoholic drink in Korea. Recently various beers are imported from the world, and many craft breweries serving variety of beers to consumers, thus Korean enjoy heyday of the beer culture.

The aim of this study was to evaluate the biomass and lipid production of Chlorella vulgaris and its nutrient removal capability for treatment of brewery wastewater effluent. The results indicate that the maximum biochemical oxygen demand (BOD) (91.43%) and chemical oxygen demand (COD) (83.11%) were removed by C. vulgaris with aeration in the absence of light. A maximum of 0.917 g/L of dry biomass was obtained with aeration in the dark conditions, which also demonstrated the highest amount of unsaturated fatty acids at 83.22%. However, the removal of total nitrogen (TN) and total phosphorus (TP) with these aeration and light conditions was 9.7% and 11.86% greater than that of other conditions. The removal of BOD and COD and the production of biomass and lipids with aeration in the dark and the TN and TP removal with aeration and light were more effective than other conditions in the brewery wastewater effluent in the presence of C. vulgaris.

This experiment was carried out to investigate the nutritive value of brewery's activated sludge on the performance and nutrients utilization of egg type chicken of babcock fed the different levels of sludge. The chemical composition, content of amino acids and mineral in brewery's activated sludge were also analyzed. 3,6,9 and 12% of brewery's activated sludge were supplemented with basal ration as a substituted ingredient to soybean oil meal in experimental ration. The results obtained were as follow: 1. Chemical composition analysis 1) Brewery's activated sludge had 42.50% of crude protein on the air dried basis, and had 15,69% of crude ash, and had 2,060 kcal of metabolizable energy per kg of sludge. 2) Total amino acid content of brewery's activated sludge was 42.50% and 99% crude protein of brewery's activated sludge was a true amino acid, and brewery's activated sludge contained especially more methionine and threonine that those of soybean oil meal. 3) In case of mineral content of brewery's activated sludge, phosphorus, magnesium, copper and iron were plentifully included. However, calcium content in brewery's activated sludge was very low. 2. Feeding trial 1) Body gain of chicken fed the different levels of sludge was decreased in proportion to increasing level of sludge was decreased in proportion to increasing level of sludge. However, no statistical differences were found out between treatments. 2) Diet intake of chicken fed the different levels of sludge was significantly (p<0.05) increased as the supplementation level of sludge in ration increased. 3) Feed conversion of chicken fed the different levels of sludge was high in proportion to increasing level of sludge in ration. However, there were no significant differences between treatments. 3. Digestion trial 1) Utilization of dry matter of chicken fed the different levels of sludge was decreased as the level of sludge in ration increased. However, no statistical differences were found out between treatments. 2) Utilization of crude protein of chicken fed the different levels of sludge was significantly (p<0.01) increased as the level of sludge was higher. Utilization of crude protein of control treatment and of sludge 3% treatment was higher than that of other treatments. 3) Utilization of crude ash of chicken fed the different levels of sludge was significantly (p<0.05) decreased in proportion to increasing level of sludge in ration. 4) Utilization of NFE of chicken fed the different levels of sludge was slightly decreased in proportion to increasing level of sludge in ration. However, no statistical differences were found out between treatments. Therefore according to this experiment, it may be concluded that brewery's activated sludge can be supplemented with chicken ration by $6{\sim}9%$.

Nightsoil and brewery sludges usually contain a high concentration of organic matters. A composting study using reactors was carried out for the recycle of brewery wastewater sludge and nightsoil treatment sludge, which have been landfilled. A good composting process was obtained with a sludge mixing ratio of 1:1 and injual pH had no effect on temperature increase related to microbial activity. The injtial C/N ratio at approximarely 15 decreased to 13 without the increase in pH.. It was found that agitation of one time a week provided the most effective composting process.

The sludge, a waste of brewery industries, was examined for potentials as a natural organic fertilizer (or soil conditioner) for lawn. Trial products were measured for changes of physical, chemical properties in laboratory and seed germination and seedling growth in green house were also tested. The results are as the following:1The sludge from distilled liquor brewery contained high quantity of organic matter which had proper physical and chemical properties for lawn fertilizer (natural organic fertilizer, soil conditioner, top-dressing mix) . It showed good characteristics in handling and capabilities to be developed as commercial products for golf courses. 2.Sludge from beer company needs proper treatment to improve physical properties for futher degradiation. It is because aggregation of the sludge particles prevented microbial activities and changing to soluble form. 3.Green carbon can be used as carbon source for organic fertilizer production using brewery sludge, but it should not contain wood extract which inhibit seed germination and seedling growth.

본 실험은 백세주 주정박이 벼의 생육과 토양 비옥도 개선에 미치는 영향을 조사하였다. 백세주 주정박은 압착된 주박을 재 발효시켜 단식증류기로 증류하여 알코올을 회수 후 발생된다. 실험 처리구는 무시용, 요소, 주정박 처리구로 하였고, 벼 질소비료 표준시비량 11kg N/10a를 기준으로 하여 전량 기비로 사용하였다. 백세주 주정박의 유효성분과 유해성분을 분석하였고, 토양에 주정박을 시용 전 후의 이화학적 분석을 하였다. 벼 실험 품종은 오대벼(Oryza sativa L.)이고, 벼의 생육과 수량 및 미질을 분석하였다. 백세주 주정박의 pH는 3.60, 유기물함량 90.12%, 염농도 0.72ds/cm, 수분함량 88%, 질소 0.21%, 인산 0.24%, 칼리 0.09%로 나타났다. 유해성분(중금속)분석결과 비소 0.03ppm, 크롬 0.09ppm, 구리0.91ppm, 납 0.05ppm, 니켈 0.05ppm, 아연 1.30ppm, 망간 3.28ppm, 철 34.86ppm로 나타났다. 토양이화학적 분석결과 주정박 시용처리구의 유기물함량과 질소 및 인산은 각각 23.0g/kg. 0.11%, 89mg/kg로 무시용과 요소처리구에 비해 유의한 차이를 보였다. 벼 이식 후 140일째 생육분석결과 초장 82.60cm, 옆폭 1.40cm, 옆장 37.70cm, 지상부건물중 59.21g로 다른 2개 처리구에 비해 유의한 차이를 보였다. 벼의 수량은 주정박 시용 처리구가 449.0kg/10a로 무시용 89.66kg/10a와 요소 401.66kg/10a에 비해 유의적인 차이를 보였다. 백세주 주정박 시용을 통해 토양 개량 효과를 기대할 수 있고, 공시 토양의 토양 개량 효과가 벼의 생육에 긍정적인 영향을 끼치는 것으로 나타남에 따라 백세주 주정박의 토양개량제로서의 활용 가능성을 확인하였다.
