“…On the other hand, a direct use of BC is not indicated, suggesting dilution with other growing media. For organic C and total N, CSD and BC were within the framework previously reported by other studies [7,40]. CSD and BC showed levels of heavy-metal content below the limit established for the commercialization of amendment in the European Community, according to the European Regulation CE 2003/2003.…”

Although compost and biochar received high attention as growing media, little information is available on the potential of vineyard by-products for the production and use of composted solid digestate (CSD) and biochar (BC). In the present study, two experiments are reported on CSD and BC mixed with commercial peat (CP) for grapevine planting material production. Four doses (0, 10%, 20%, 40% vol.) of CSD and BC were assessed in the first and second experiment, respectively. CSD mixed at a dose of 10% recorded the highest values of shoot dry weight (SDW) and a fraction of total dry biomass allocated to shoot (FTS), both cropping bench-graft and bare-rooted vine. On the other hand, CSD mixed at a dose of 40% displayed the highest values of SDW and FTS, cropping two-year-old vine. BC used at a dose of 10% improved SDW, root dry weight, total dry weight, FTS, shoot diameter, and height on bare-rooted vine. The present study shows that CSD and BC, coming from the valorization of vineyard by-products, can be used in the production of innovative growing media suitable for nursery grapevine production. Further studies are needed to assess the combined applications of CSD and BC in the same growing media.

“…Actualmente para uso de estos residuos se elabora ensilaje para la alimentación animal, torta de pulpa de café, jugo tratado con microorganismos para el consumo animal (Noriega et al, 2009), adicionalmente han sido utilizados para cultivo de hongos (Murthy y Manonmani, 2008), producción de enzimas (Buntić et al, 2016;Ngo y Phan, 2016;Torres-Mancera et al, 2011), biocombustibles (Gouvea et al, 2009;Woldesenbet, Woldeyes, y Chandravanshi, 2016) y compostaje (Hachicha et al, 2012). Teniendo en cuenta que la pulpa de café es altamente perecedera debido a su alto contenido de humedad, se generan pérdidas por deterioro químico y microbiano (Ruiz-López et al, 2011).…”

El objetivo de este trabajo fue evaluar las condiciones de secado de cáscara de café y su efecto sobre propiedades fisicoquímicas. Se realizaron cinéticas de secado hasta 420 minutos, a 40, 50 y 60 ºC; los datos experimentales se ajustaron con 4 modelos cinéticos de capa delgada. Adicionalmente, se evaluó el contenido de cafeína y ácido clorogénico y los parámetros de color en la cáscara húmeda y seca. Se obtuvo una reducción del contenido de agua hasta el 13,5%. El modelo de Page fue el más adecuado para representar el secado a las tres temperaturas evaluadas. Respecto a los biocomponentes, la concentración se incrementó en el proceso y los cambios de color fueron superiores al 4%, generando tonalidades rojizas y cambios en el ángulo de tono, luminosidad y croma. Lo anterior demuestra que el secado es una alternativa para estabilizar este subproducto, como etapa previa para su uso industrial.

“…Thus, the degradation of lignin is closely related to the humification process. The improvement efficiency of inoculation with ligninolytic microbes on humification degree of lignocellulosic waste compost was almost universally accepted . White rot fungi are typical of lignin degrading microbes and can secrete extracellular enzymes, such as laccases and peroxidases to act on polyphenol and catalyze the hydrolysis of polymers and condensation reaction of humic substances.…”

“…The improvement efficiency of inoculation with ligninolytic microbes on humification degree of lignocellulosic waste compost was almost universally accepted. 37 White rot fungi are typical of lignin degrading microbes and can secrete extracellular enzymes, such as laccases and peroxidases to act on polyphenol and catalyze the hydrolysis of polymers and condensation reaction of humic substances. Since the mechanisms by which lignin is degraded varied for different microbes, it is necessary to explore how lignin decomposition CMs work in future studies.…”

BACKGROUND It is necessary to inoculate microbes in the composting of special materials. Biogas residue (BR) is rich in refractory lignocellulose. To improve humification processes of BR composting, composite microorganisms (CMs), with multiple functions, were added to the mixture of BR and animal manure. RESULTS The results indicated that four humification indices (DP, PHA, HR, HI) were all markedly higher in the inoculated compost (0.46, 27.5, 43.34, 11.92) than in the uninoculated compost (0.39, 22.53, 28.56, 6.49) (P < 0.05). The inoculation increased the degree of polycondensation and aromatization, and molecular size, as well as the humification degree of BR compost as determined by fluorescence spectroscopy and fluorescence regional integration analysis of humic acids, fulvic acids and hydrophilic fraction, three chemically isolated fractions. Additionally, the inoculation increased the quantity and diversity of indigenous microorganisms and accelerated their proliferation by adjusting environmental conditions to optimize their growth. CONCLUSION The CMs inoculant is suitable for BR composting and inoculating based on the composition of the composting substrate could enhance composting efficiency and improve compost quality. © 2014 Society of Chemical Industry
