Aceleración del proceso de compostaje de residuos post-cosecha (pulpa) del café con la aplicación de microorganismos nativos Composting process acceleration of post-harvest product (cherry) coffee with the implementation of native microorganisms

摘要: Colombia, as a leading exporter of coffee smooth, in 2008 produced an average 12 524 thousand bags coffee, each 60 kg, which 3 005 tones are cherry, these large volumes post- harvest, considered contaminants. These products can be used to produce organic fertilizer. The traditional composting process takes about 150 days because that the decreasing time 40 days, it is proposed. Isolation microorganisms from pre-enrichment basal medium cherry Saline (MBS) obtain axenic cultures, were identified and tested for compatibility between consortia select strains tested. Four 4 biopiles made with weight 175 kg one control. They inoculated by spraying concentration x 10 CFU/mL during 10, 20 7 30 monitoring physical parameters. isolated 8 strains: Pseudomonas aeruginosa, Citrobacter koseri, Bacillus sp, Escherichia coli, Stenotrophomona maltophilia, Cromobacterium spp, spp. carbon- nitrogen (C/N) ratio stack 1 (9.6 %), 2 (10 pile (9.5 %) fulfilled established values (< showing maturity sanitary quality low levels fecal coliform total absence Salmonella. results allowed compost meets parameters Colombian technical standard (5167 NTC,
