  • 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.

  • Two experiments were carried out to evaluate the effects of brewery waste (BW) replacement of concentrate (C) in growing duck diets. In Exp. 1, which was carried out on-station, 300 ducklings were allocated in a $2{\times}5$ factorial experiment: Two breeds (local Muscovy and crosses of French and local Muscovy)${\times}5$ levels of C and with BW offered ad libitum. Concentrate only ad libitum as the control diet (C100), and levels of 75% (C75), 50% (C50), 25% (C25) and 0% (C0) of the amount of the control diet consumed, and with BW ad libitum. In Exp. 2, 200 ducklings were allocated in a $2{\times}2$ factorial experiment on five smallholdings: two breeds (local and crossbred Muscovy ducks)${\times}2$ diets (the C100 and C50 diets from Exp.1). In Exp.1 total dry matter (DM), BW, crude fiber (CF) and crude protein (CP) intakes were highest on the C0 diet and ME and lysine intakes lowest (p<0.001). Daily live weight gains were higher for the crossbred ducks than for the local Muscovies (p<0.05) and were highest for treatments C100 and C50, and lowest for treatment C0 (p<0.05). Weights of breast muscle, liver and abdominal fat were significantly higher for the crossbred ducks. Breast and thigh muscle and abdominal fat weights were significantly higher for the C100, C75 and C50 diets, while gizzard weights were highest for the C25 and C0 treatments. Net profits were higher for the crosses, and for treatments C50 and C25. In Exp. 2 total DM, CF and CP intakes were significantly higher for the C50 diet, and ME intakes lower (p<0.001). Daily gains of the crosses were significantly higher than those of the local Muscovy ducks, and were similar for the C100 and C50 diets. The highest net profits were from the crosses and ducks fed the C50 diet. It was concluded that BW can replace 50% of the concentrate in growing Muscovy duck diets without reducing daily live weight gains and with improved economic benefits.

  • The optimum condition for production of yeast extract by autolysis and enzymatic method were studied with waste brewers\` yeast. The major components of brewer\`s yeast in proximate compositions were carbohydrate(46.0%) and protein(41.7%). There was a little appreciable difference in the promaximate composition of waste brewers\` and bakery yeast. The major minerals were identified as K, P, Mg and Ca, and their contents were about 1,659.7%, 1,197.4mg%, 210.4mg% and 105.6mg%, respectively. The major vitamins were identified as vitamin C and vitamin B group, and their contents were about 7.9IU/100g and 4.2IU/100g, respectively. The optimum yeast concentration in the reaction suspension was 10% (w/v) waste brewer\`s yeast slurry. The protein content in brewer\`s yeast extract was increased with addition of NaCl as plasmolyzers. However, the plasmolyzer effect of ethanol a little showed as the concentration increasd from 3% ∼7%. The 5\`-nucleotides(5\`-GMP and 5\`-IMP) content in brewer\`s yeast extract was increased with addition of glucanase. The total content of 5\`-nucleotides (5\`-GMP and 5\`-IMP) increased by 160% than those by the autolysis of waste brewer\`s and bakery yeast.

  • A series of bench scale activated sludge units were operated to find the causes of filamentous bulking(Schizothrix calcicola) at the Southerly Wastewater Treatment Plant. The results shows that the algal bulking problem is caused by the combination of fermented brewery waste and a low/high DO pattern in the aeration basin. The volatile fatty acids in the influent are not themselves the only cause of bulking but indicators of an unidentified substance that either suppresses zoogloeal growth or stimulates algal growth during low DO conditions, because the volatile fatty acids do not stimulate algal growth unless they are added to a sewage that already contains, some fermented brewery waste.

  • The effects of the processing mixture of pig manure and various organic wastes on the growth, cast production of earthworm, and conversion of organic matter to earthworm tissues by vermicomposting. The substances used in this experiments were sawdust, rice hull, coffee waste, brewery waste, litters, turfgrass cutting residues, rice bran, vegetable wastes and rice straw and were mixed with pig manure at a ratios of 50:50 (v/v), and pig manure 100% (control), respectively. The highest values of growth parameters, cast production and conversion efficiency of organic matter to earthworm tissues were obtained at the mixtures of pig manure with coffee waste, it may due to the favourable diet conditions to process with pig manure by vermicomposting. But, all of the earthworm died in the pig manure 100% (control) and pig manure with vegetable wastes treatments by vermicomposting was impossible in this experiment. The vermicast contained a higher values of total nitrogen, available phosphorus, exchangeable cations and cation exchange capacity than their parent materials with increased availability of nutrients and improved physicochemical properties.

  • Where the industrial waste is increasing in number of kind and in quantities by the industrialization and population increases, the pollution problem is not only national but grobal question of the day. This paper is trying to invite attentions by the people who are working in both sector-natural sciences and industries in reviewing limited reports and materials. 1. By the chemical evaluation of over 20 industrial waste produced in Korea, potential wastes for commercial fertilizer would be wastes from alcohol fermantation, beer brewery, leather processing, synthetic fiber, and coffee grounds. 2. The composition of city waste is differ from other countries and sludge cake from human feces processing is promising one in the organic matter and phosphate content particularly. However, the content of heavy matals, specific order, and availability of phosphate are the bottle-neck for the development. 3. There is one commercial fertilizer from industrial waste in the market. It is very reasonable in the content of nitrogen and organic matter, and its formulation and responeses on crops. 4. Discussions were also given on the general problems in processing and marketing of fertilizers from industrial waste, however, scientists and industrial owners have to pay more attention on the development of fertilizers from tire industrial wastes because of vital environmental protection view-point.

  • Strain Kw07$^T$, a Gram-negative, non-spore-forming, rod-shaped bacterium, was isolated from granules in an Up-flow Anaerobic Sludge Blanket (UASB) bioreactor used in the treatment of brewery waste­water. 16S rRNA gene sequence analysis revealed that strain Kw07T belongs to the a-4 subclass of the Proteobacteria, and the highest degree of sequence similarity was determined to be to Sphingopyxis macrogoltabida IFO 15033T (97.8%). Chemotaxonomic data revealed that strain Kw07T possesses a quinone system with the predominant compound Q-I0, the predominant fatty acid C,s:, OJ7c, and sphingolipids, aU of which corroborated our assignment ofthe strain to the Sphingopyxis genus. The results of DNA-DNA hybridization and physiological and biochemical tests clearly demonstrated that strain Kw07T represents a distinct species. Based on these data, Kw07T (= KCTC 12209T = NBRC 100800T) should be classified as the type strain for a novel Sphingopyxis species, for which the name Sphingopyxis granuli sp. novo has been proposed.

  • The lees of Korean traditional wine called as Jubak or Sul-jigemi in Korea is byproduct from alcohol fermentation industry, which is remnant of fermentation broth after filtration, centrifugation, distillation, or sedimentation during aging. Since, Korean traditional wines are produced from edible plant sources such as rice, foxtail millet, fruits and medicinal herbs with nuruk (a traditional fermentation starter and starch degrader), the Jubak from rice wine (takju), medicinal herb wine (yakju) and fruits wine are considered as safe byproduct and have various useful bioactivity. Considering the recent rapid increased production of Jubak from takju industry, and the reinforcement of dispose of Jubak as waste material in worldwide, the development of efficient reuse process for Jubak is necessary in traditional wine industry. In this review, the status of current industry, research and patent trends in relation with Jubak production, treatment, utilization and renewal was analyzed and different bioactive compounds including phenolic acids from Jubak were provided. Jubak is not any more waste material, and is the source of bioactive functional materials for food, cosmetics and medicinal industry. To develop the efficient and economic renewal technology including recovery process for bioactive substances from Jubak, systematic collaboration and research among the industry, academy and government is necessary.

  • The aims of this study were to compare the biomethanation of CO2 through specific methanogenic activity (SMA) test which was inoculated with four different types of mixed microbial culture obtained from full-scale anaerobic digestion (AD) plants. The experimental results showed that CH4 conversion was the highest in the samples inoculated by seed sludge taken from ADs of food waste and brewery; under this condition, the produced biomethane contains 89.3-91.9% of CH4. Meanwhile, the lowest level was obtained in the sample from sewage sludge. The measured ratio of CH4 production rate to CO2 consumption rate in all reactors was higher than the theoretical value (1) in the middle of the period and soon dropped to 0.7-0.8. It might be due to changed metabolic pathways in the reactor by the degradation of residual organic matter and the increased activity of homoacetogenic bacteria.

  • In this study, granular sludge used in an anaerobic process treating brewery waste was inoculated in a laboratory scale of reactor to induce anaerobic ammonium oxidation(ANAMMOX). The reactor was operated with synthetic wastewater, which prepared at 1:1 ratio of $NH_4^+-N$ over $NO_2^--N$. Changes in nitrogen concentration, COD, alkalinity and gas production were analyzed. There are 3 phases of spanning in experimental period according to influent nitrogen concentration. In the Phase 1, each of the concentration of $NH_4^+-N$ and $NO_2^--N$ were increased from 1.91 $gN/m^3{\cdot}d$ to 14.29 $gN/m^3{\cdot}d$. Ammonium nitrogen loading(same as nitrite nitrogen) was 23.81 $gN/m^3{\cdot}d$ in the Phase 2 and 19.05 $gN/m^3{\cdot}d$ in the Phase 3, respectively $NO_2^--N$ has been removed up to 99% during whole period while the removal efficiency of $NH_4^+-N$ was significantly varied. In Phase 2, $NH_4^+-N$ was removed up to 75%. Microorganisms varied temporally through three phases were characterized by 16s rDNA analysis methods. ANAMMOX bacteria were dominantly found in phase 2 when the removal rate of $NO_2^--N$and $NH_4^+-N$ was the highest up to 99% and 75%, respectively. Due to erroneous exposed to air, the removal efficiency of $NH_4^+-N$ was unexpectedly lowered, but ANAMMOX bacteria still existed.
