| The experiment was conducted to evaluate losses and nutritive value of elephant grass silage containing increasing levels of cottonseed meal. The experimental design was completely randomized, with five treatments: 0, 7, 14, 21 and 28% inclusion of cottonseed meal, and four replications. The material was chopped and packed in PVC silos and stored for 80 days. The pH and dry matter (DM), crude protein, lignin and ether extract of the silages increased linearly with the addition of cottonseed meal, while the levels of acid detergent insoluble nitrogen, neutral detergent fiber, acid detergent fiber, cellulose and hemicellulose decreased linearly. The addition of 28% cottonseed meal reduced the in situ disappearance of DM (48h) to values lower than those of... |

| This trial evaluated the addition of Lactobacillus plantarum, L. brevis and Enterococcus faecium combo additive against a control treatment. The silages were made in laboratory silos that were stored for 30, 60, 90 or 120 days before opening. We evaluated the chemical composition of the forage before and after ensiling and the fermentative losses of silages. The additive decreased (p < 0.01) effluent production (11.4 kg ton-1) compared to control silage (14.0 kg ton-1), but it increased (p < 0.01) the Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) from 45.6% and 24.5% to 47.0 and 25.1% for control and additive silages, respectively. The storage periods affected (p < 0.01) effluent production, Dry Matter Losses (DML), NDF,... |

| A intensa produção de peixes e uso dos recursos hídricos pode comprometer a qualidade e disponibilidade da água, além de afetar a capacidade de suporte do ambiente, causando eutrofização e conseqüentemente a poluição do mesmo. Realizou-se um estudo das variáveis físico-químicas da água e dos teores de fósforo total (P-total) no sedimento, rações e peixes cultivados em tanques-rede em uma área aqüícola localizada no reservatório da Itaipu, no município de Santa Helena – PR, objetivando monitorar a qualidade da água e determinar o índice de eutrofização total da área de cultivo, além de analisar a bioacumulação de P-total nos peixes e sedimento. As variáveis físico-químicas da água mantiveram valores normais indicados pelo CONAMA. A concentração média de... |

| The aims of this study were to quantify the effects of fibrolytic enzyme additives applied to each of four consecutive cuts of unwilted grass at ensiling on ensilage characteristics and specific CH4 yields (SMY) per unit mass and per unit land area. In light of the importance of the primary growth yield, the effects of the timing of Cut 1 were also investigated. Furthermore, the mass-SMY and area-SMY effect of any effluent produced during ensilage was determined.At each of four cuts that comprised annual growth, samples from four replicate plots of Lolium perenne and of Phleum pratense were untreated (control) or were treated with either of two fibrolytic enzymes (ENZ 1 and ENZ 2) prior to ensiling for 120 days. The mass-SMY of silages and effluents were... |

| ABSTRACT The lipases have ability to catalyze diverse reactions and are important in different biotechnological applications. The aim of this work was to isolate and characterize microorganisms that produce lipases, from different food industry effluents localized in Pelotas, RS/Brazil. Bacteria were identified using Gram stain and biochemical tests (Vitek 2(r)). Fungi were identified according to macro and micromorphology characteristics. The extracellular lipase production was evaluated using the Rhodamine B test and the enzymatic activity by titration. Twenty-one bacteria were isolated and identified as Klebsiella pneumoniae ssp. pneumoniae, Serratia marcescens, Enterobacter aerogenes, Raoultella ornithinolytica and Raoultella planticola. Were... |

| The effectiveness of the anaerobic treatment of effluent from a swine and bovine slaughterhouse was assessed in two sets of two-phase anaerobic digesters, operated with or without temperature control. Set A, consisting of an acidogenic reactor with recirculation and an upflow biological filter as the methanogenic phase, was operated at room temperature, while set B, consisting of an acidogenic reactor without recirculation and an upflow biological filter as the methanogenic phase, was maintained at 32°C. The methanogenic reactors showed COD (Chemical Demand of Oxygen) removal above 60% for HRT (Hydraulic Retention Time) values of 20, 15, 10, 8, 6, 4, and 2 days. When the HRT value in those reactors was changed to 1 day, the COD percentage removal decreased... |

| ABSTRACT We evaluate the application of treated sanitary wastewater (TSW) to provide potassium for crops and reduce demand for fresh water and mineral nutrients. The field experiment was arranged in randomized block design with four replications and five treatments: 50, 100, 150 and 200% of potassium requirements and a control with conventional fertilizer. The TSW was applied to maize (November 2012 to February 2013), cotton (June to November 2013) and bean (April to June 2014). After bean, soil chemical properties were evaluated until 0.8 m depth. Fertigation with TSW to potassium fertilization provided about 50% of water, nitrogen and phosphorus to the bean. The soil nutrient availability and soil organic matter did not increase, whereas sodium had... |

| The genotoxicity of untreated and treated sewage from two municipal wastewater treatment plants (WTP BN and WTP SJN) in the municipality of Porto Alegre, in the southern Brazilian state of Rio Grande do Sul, was evaluated over a one-year period using the Tradescantia pallida var. purpurea (Trad-MCN) bioassay. Inflorescences of T. pallida var. purpurea were exposed to sewage samples in February (summer), April (autumn), July (winter) and October (spring) 2009, and the micronuclei (MCN) frequencies were estimated in each period. The high genotoxicity of untreated sewage from WTP BN in February and April was not observed in treated sewage, indicating the efficiency of treatment at this WTP. However, untreated and treated sewage samples from WTP SJN had high... |

| Marine land-based fish farms located in coastal wetlands (salt-pond zones, lagoon banks, etc.), whether extensive or intensive, send farm effluents directly to the sea or after short periods of stocking in retention reservoirs. The aims of our investigation have been to compare the efficiency of current and potential water treatment procedures in open-air. Wastewater retention ponds in commercial farms (Atlantic coasts of France) are efficient in removing up to 1 metric ton of particulate material (dry weight) per hectare and per day (faeces and unconsumed feed), but are inefficient in reducing dissolved wastes, both organic (urea, amino acids, protein) and inorganic (total ammonia nitrogen, phosphates). Forthcoming outdoor technology to treat these forms... |

| An experiment was conducted in six earthen ponds with 20 shrimps m(-2) Litopenaeus stylirostris (Stimpson) during the warm season in New Caledonia to study the dynamics of wastes in relation with water exchange rate (WER). The nitrogen budget was established, taking into account the different forms of nitrogen in the water, sediment, feed and shrimp. Data from a wide range of treatments applied in unreplicated ponds were treated using regression analysis to establish the relationship between WER and partial nitrogen budget, sediment characteristics and shrimp performance. To compare effluent quality between treatments during the season, data were analysed using the non-parametric sign test. The water outflow was characterized by a decrease in the... |

| Sea fish farms with production of more than 20 tons per year in France must obtain two operating licences: (i) one for Sea Farming (AECM), with the aim of ensuring that the granted site and use of the maritime public domain for exploitation will respect all restrictions of general interest; (ii) one for regulating Facilities Classified for the Protection of the Environment (ICPE). Although the first one requires a relatively simple licence request file, the second one demands a very complete file, which includes, beyond the notice of exploitation information, a complete impact study, as well as a hazards study and a health and safety notice. In this context, petitioners in Corsica (adjustment of status or new exploitation) are faced with the same... |

| The paper describes the derivation and effectiveness of a benthic macrofauna environmental quality standard (EQS). The EQS is derived from a continuing, long-term (24 years) monitoring programme, designed to determine the effect of mining effluent discharged into coastal waters off the NE coast of England. The area under study is at the Cleveland Potash mine at Boulby. Benthic monitoring began there in 1970 and live years of baseline data were gathered before discharge commenced in 1974. During the course of the monitoring programme (1970-1993) annual surveys have been completed at the discharge point and at more distant reference sites. The complete data set includes results from over 1000 benthic grab samples. The effect of the discharge is clearly... |

| Dairy farming in the Waikato Region has contributed greatly to the reduction of water quality. Part of this is attributable to the issue of inappropriate disposal of dairy effluent. Regional authority data shows both costs and benefits of complying with effluent management regulations. Private costs result from system and management improvements, while private benefits are largely due to reduced fertiliser requirements. Decreases in the volume of 'non-compliant effluent', resulting from improved compliance, are used as an indicator to illustrate reduced environmental effects. The benefits of becoming compliant outweigh the costs for half the farms analysed. More incentives are required to promote compliance from the other farms although their environmental... |
