“…On the other hand, from day zero, there was an increase in temperature reaching 39.6 ºC at 15 days of composting, demonstrating the growth and development of mesophilic microorganisms in the biomass. Bacteria, fungi, and mesophilic actinomycetes, which are dominant in the first three days of composting, feed on readily available organic matter components such as sugars, amino acids, proteins and nucleic acids, rapidly causing temperature rise due to the release of heat by part of the microbial metabolism (VERGNOUX et al, 2009). However, the persistence of these microorganisms in the period suggests that the colonization of the biomass by the thermophilic microbiota may have been impaired by the moisture content (62.8%) of the substrate mixture.…”

SUMMARYThis trial evaluated the composting for valuation of marine fish waste. The study was carried out in a composting cell (1.10m length, 1.50m width, 1.20m height, and 2.50m headroom), which received a mixture of marine fish waste (skin and fin) and reused wood shavings at a 7:3 proportion. The efficiency of the composting process was evaluated through analysis of biomass temperature, moisture, pH, ash, compost mineralization index, carbon/nitrogen ratio, total organic matter, total organic carbon and total nitrogen. Data were tested by analysis of variance and polynomial regression, and the means compared by Tukey's test at 5%. The results showed that composting is an efficient alternative for the valuation of fish residues. The compost complies with the Brazilian Standards (Normative Instruction 25/2009 of the Brazilian Ministry of Agriculture, Livestock and Food Supply). The C/N ratio lower than 15/1 combined with the high moisture content of the substrates inhibit the increase in the biomass temperature. The wood shavings reused for three consecutive times provide nitrogen. The addition of water to the composting process should be suppressed when using the proportion of 7kg fish waste and 3kg reused wood shavings.Keywords: compost, environment, fish, water resources RESUMOObjetivou-se avaliar a compostagem na valoração de resíduos de pescado marinho da Colônia de Pescadores Z-3. O experimento foi realizado em uma composteira em célula nas dimensões 1,10 m de comprimento, 1,50 m de largura e 1,20 m de altura, com pé direito de 2,50 m, que recebeu a mistura de resíduos de pescado marinho (pele e barbatana) e maravalha de pinus reutilizada na proporção 7:3. A eficiência do processo de compostagem foi avaliada através das análises de temperatura da biomassa, umidade, pH, cinzas, índice de mineralização do composto, relação carbono/nitrogênio e os teores totais de matéria orgânica, carbono orgânico e nitrogênio. Os dados foram submetidos á análise de variância e regressão e as médias comparadas pelo teste de Tukey a 5%. Os resultados demonstraram que a compostagem é uma alternativa eficiente para a valoração dos resíduos de pescado da Colônia de Pescadores Z-3. O composto produzido atende a Instrução Normativa no. 25/2009 do Ministério da Agricultura, Pecuária e Abastecimento, para ser comercializado como fertilizante orgânico. A relação C/N menor que 15/1 associada á alta umidade da mistura dos substratos inibem o aumento da temperatura da biomassa. A maravalha reutilizada por três vezes consecutivas serve como fonte de nitrogênio. A adição de água ao processo de compostagem deve ser suprimida quando for utilizada a proporção 7 kg de resíduos de pescado para 3 kg de maravalha reutilizada.Palavras-chave: composto, meio ambiente, peixe, recursos hídricos Rev.

“…Galvez-Sola et al [45] used PLS1 to predict different compost quality parameters such as pH, electric conductivity, total organic matter, total organic carbon, total N, C/N ratio as well as nutrients contents (N, P, K) and potentially pollutant element concentrations (Fe, Cu, Mn and Zn) from near infrared spectra. Vergnoux et al [21] applied a PLS1 to predict physico-chemical and biochemical parameters from NIR spectra. Physico-chemical parameters comprised age, organic carbon, organic nitrogen, C/N, total N, fulvic acids (FA), humic acids (HA) and HA/FA.…”

“…Tracking and interpreting the processing stages between start and endpoint is however difficult and fraught with uncertainty [26][27][28][29] even though general requirements and priorities regarding composting principles have emerged [30][31][32]. Of particular interest are practical methods that would allow analyzing the state of fragmentation of polysaccharides undergoing biodegradation.…”

We describe a simple method for tracking the course of microbial degradation of polysaccharide-rich feedstocks. The method involves determining total polysaccharides present in the feedstock, measured in glucose equivalents, relative to the fractional component of polysaccharides exhibiting 2,3-dinitrosalycylic acid aldehyde activity. The ratio of total polysaccharide to aldehyde activity, defined as the end-point fragmentation (EPF) index, is then calculated and tracked as it shifts as microbial degradation of polysaccharide-rich feedstock progresses. While degradation occurs, the EPF index falls. It bottoms out at an asymptotic limit marking the point in time where further degradation of the polysaccharide-rich feedstock has ceased. The EPF index can be used to follow the progressive breakdown of composting polysaccharide-rich waste. It may also have applicability as a means of tracking the turnover of polysaccharides in other complex environments including soil, sediments, wetlands, and peat bogs.
