친환경축산에 앞장서는 생균제 산업 - 사료용 생균제의 개발 및 이용 현황

김태일,Kim, Tae-Il 한국단미사료협회 2004 사료산업 Vol.2 No.6

현대는 인간의 복지와 환경보호의 양면을 중요하게 여기는 시대이다. 생물을 담보로 생산성을 추구하는 모든 산업이 환경에 친화적이면서 인간복지에 기여하는 산업으로 접목되기를 강요하고 있는 시대다. 이러한 현상은 범세계적인 추세다. 이러한 대전제에 부응한 산업이 되었을 때 얻게되는 수익에서 수익의 합리성을 찾을 수 있고 지속적인 성장이 기대되는 산업으로 보장받을 수 있기 때문인 것으로 생각된다. (중략)

본 연구는 국내에 설치되어 있는 액비저장조의 운영실태를 조사하고, 액비저장조에서 발생되는 악취물질을 구명하고자 수행하였다. 1. 국내에 200톤 규모의 액비저장조를 설치한 60 농가를 대상으로 한 본 조사에서 약 $93\%$가 액비저장조를 제대로 가동을 하고 있었으며 이중 $57\%$가 액비제조시 폭기 처리하고 있었다. 2. 조사 농가 중 년간 액비의 활용 횟수는 2회가 $50\%$로 나타났고 액비의 부숙 효과를 높이고 악취를 저감시키기 위한 목적으로 $64\%$가 미생물제제를 첨가하고 있었다. 반면에 액비 이용시 인력 장비의 비용 및 악취물질 발생 저감을 위한 첨가제 비용이 $43\%$로 조사되어 액비이용 시 문제점으로 지적되었다. 3. 액비 제조 형태별 악취물질 발현양상으로 호기 제조시 액비저장조내에서는 iso-valeric acid가 0.012에서 0.07ppm, Propionic acid가 $0.17\~2.85ppm$의 범위로 검지되었으며 혐기 제조시에는 n-Butyric acid가 1.5에서 2.3ppm, n-valeric acid가 $1.3\~1.8ppm$, acetaldehyde가 0.8에서 2.1ppm로 검지되어 호기 제조방법과 혐기 제조방법 모두 휘발성 지방산의 농도는 악취방지법의 규제농도 이상이었다. 부지경계선에서의 악취물질을 보면 호기시에는 미검출로 나타났고 혐기 제조시에는 Acetaldehyde가 $0.4\~0.9ppm$ 수준으로 검지되어 악취방지법의 규제농도를 초과였다. This study was carried out to determine the acceptability of liquid manure bin among livestock farmers and agricultural farmers, and quantify its malodorous compounds. The results were as follows; 1. The size of the manure bins owned by $93\%$ of 60 farmers surveyed was 200 M/T and were all in normal operation. Around $57\%$ of the normally operated bins were processed under aerobic condition. 2. Filly percent of the respondents utilized their liquid manure bin twice a year while $64\%$ used commercial microbial products to enhance maturity of their liquid manure and abatement of malodorous emissions. On the other hand, $43\%$ mentioned problems on the labor requirement, mechanical maintenance and lending cost of liquid manure processing and utilization, and the price of the commercial microbial products. 3. Malodorants emitted from livestock liquid manure bins and their boundary bin depended upon the livestock liquid manure processing condition. Within bin under the aerobic processing condition, Iso-valeric and propionic acid were ranged 0.012 to 0.07ppm and 0.17 to 2.85ppm, respectively. Within bin under the anoxic processing condition, n-butyric, n-valeric acid, and acetaldehyde were ranged 1.5 to 2.3ppm, 1.3 to 1.8ppm, and 0.8 to 2.1ppm, respectively. Malodorants emitted from the boundary of livestock liquid manure bins under the anoxic processing condition were detected the range of 0.4 to 0.9 ppm, more than the concentration of law regulation, as an acetaldehyde, but under the aerobic processing condition, they did not any detection.

김태일,유용희,정의수,양창범,김민균,Kim, T. I.,Yoo, Y. H.,Chung, E. S.,Barroga, Antonio J.,Yang, C. B.,Kim, M. K. 한국축산환경학회 2005 축산시설환경학회지 Vol.11 No.2

본 연구는 돈 분뇨 액비에 미생물 첨가가 배추의 발아지수에 미치는 효과를 구명하기 위해서 수행하였다. 돈 분뇨 액비는 107일 동안 폭기와 무폭기 상태로 액상비료를 제조하여 공시하였고 미생물 첨가는 $0.05\%,\;0.1\%,\;0.2\%,\;0.3\%$ 수준으로 하였다. $0.05\%$ 미생물 접종 처리구에서 식물 독성이 낮고 발아지수가 높게 나타났다. 첨가수준별 돈분 액비 이용시험에서 초기 돈 슬러리의 액비성상은 T-N 2,873 ppm, T-P 753 ppm, $NH_4-N$ 1,441.6 ppm, $NO_3-N$ 16.48ppm으로 50일이 되면서 폭기조건에서 T-N 3,672 ppm, T-P 164 ppm, $NH_4-N$ 183.87 ppm, $NO_3-N$ 21.97 ppm로 변화하였으며, 무폭기 조건에서 T-N 1,261 ppm, T-P 68 ppm, $NH_4-N$ 161 ppm, $NO_3-N$ 16.87 ppm로 나타났다. 미생물을 처리하지 않고 107일동안 폭기조건과 무폭기 조건으로 액비화한 시료의 발아지수는 각각 83과 40.4이였다. 돈 분뇨 액비를 무산소 제조시 $40\%$ 이상, 호기제조시 $50\%$ 이상의 발아지수가 개선되었다. 이와 같은 결과는 액비제조 처리가 무산소 제조보다는 호기제조 처리가 작물에 양호한 것으로 판단되어지며 이는 호기처리시 총질소의 함량을 높게 유지할 수 있도록 하는 결과인 것으로 사료된다. This study was carried out to investigate the effect of Synechocystis sp. KACC 91007 when added to a pig slurry or pig liquid fertilizer (PLF) on germination index (GI) of Chinese cabbage. The preliminary experiment involved the screening of inoculant levels which were; 0.05, 0.1, 0.2, and $0.3\%$, respectively. The $0.05\%$ level of inoculant was selected based on low phytotoxicity and high GI.. The PLF underwent a 107 day aerobic and anoxic processing conditions. The T-N, T-P, $NH_4$, and $NO_3-N$ concentrations of the untreated pig slurry were; 2,873, 753, 1,441.6, and 16.48 ppm, respectively. Using aerobic processing treatment, the fertilizer value of the PLF was 3,672, 164, 183.87, and 21.97 ppm, respectively. In contrast, the fertilizer value of the PLF processed under anoxic condition was reduced to 1,261, 68, 161, and 16.87 ppm. The GI value of the untreated PLF under aerobic and anoxic processing condition was 83 and $40.4^{*}\%$, respectively. With the addition of the $0.05\%$ microbial inoculant, the GI improved by more than 40 and $50\%$ respectively, when the PLF was processed under anoxic and aerobic conditions. The above findings proved that the aerobic processing of PLF for 107 days was better than anoxic and yielded higher T-N which is a macro-nutrient fertilizer material. Consequently, the addition of $0.05\%$ microbial inoculant resulted to a higher GI of the Chinese cabbage specifically under aerobic processing condition.

The assessment of alveolar bone changes on dental radiographs to indicate progression of periodontal diseases or healing response to therapy is routine procedure. However, the diagnostic accuracy in detecting small alveolar bone changes is very limited. Recently, guided bone regeneration therapy is popular, but the quantification of new bone is somewhat difficult with conventional evaluation method. To quantificate the amount of new bone, various evaluating methods have been introduced including histomorphometry, radiomorphometry, biochemical analysis, X-ray probe microanalysis, scanning electron microscope backscatter method. In this study, guided bone regeneration using resorbable membrane with & without PDGF-BB is quatificated through histomorphmetry to evaluate the efficacy of histomorphometric analysis. 4 beagle dogs and 8 Sprague-Dawley rats were selected as experimental animals. In beagle dog experiment, $4{\times}4mm$ Class II defects were created in maxillary both second premolars, and biodegradable membrane containing PDGF-BB(experimental group) were covered over one defect, and same membrane without PDGF-BB(control group) were covered over the other defect. At 2 weeks, 5 weeks after surgery, each beagle dogs were sacrificed, and the tissues were treated by undecalcified fixation. In Sprague-Dawley rat experiment, 5mm round defect were created in temporal bone, the same membranes were covered on the defects. At 1 week, 2 weeks after surgery, each rats were sacrificed, and undecalcified fixation were taken. After grinding tissue specimen, we analyse them histomorphometrically using image analysis system. In beagle dog 2 weeks specimens, new bone formation area were $0.03123mm^2$ in experimental group,and $0.03012mm^2$ in control group. At 5 weeks specimens, $0.15324mm^2$ in experimental group, and $0.09123mm^2$ in control group. In Sprague-Dawley rat specimens, new bone fomation area were $0.20448mm^2$ in 1 week experimental group, $0.03604mm^2$ in 1 week control group. At 2 weeks specimens, $0.46349mm^2$ in experimental group, $0.17741mm^2$ in control group. The results indicated that histomorphometric analysis of new bone formation using image analysis system is very effective quantification method to evaluate the efficacy of treatment modalities.

It has been reported that Magnoliae cortex extract has antibacterial and antimicrobial activity against pathogenic microbes and Zea Mays L. extract is effective for improving gingival tissue health. The purpose of this study was to examine the anti-inflammatory and antimicrobial effects of Zea Mays L. and Magnoliac cortex extract mixtures through experimental peridontitis induced beagle dog model. Nine beagle dogs with experimentally induced periodontitis were selected. Baseline clinical indices which includes plaque index, gingival index, probing pocket depth, clinical attachment level, gingival fluid flow rate were recorded and microbial assays were done. Magnoliac cortex and Zea Mays L., mixed at 2:l ratio in 105mg capsular dosage, were taken by 3 capsule (Group I) or 6 capsule dosages (Group II) three times a day. After 4,8,12 weeks, clinical indices were recorded. All data of clinical indices were compared through one-way ANOVA with 95% confidence level. Clinical indices of group I and II showed significantly better results than those of control group. There were no significant differences between group I and II. In conclusion, it was confirmed that mixture of Magnoliae cortex and Zea May L. (mix ratio 2:1) possessed clinical improving effects to periodontitis.
