INFLUENCIA DE BACTERIOCINAS PRODUCIDAS POR Lactobacillus plantarum LPBM10 SOBRE LA VIDA ÚTIL DE FILETES DEL HÍBRIDO DE CACHAMA Piaractus brachypomus x Colossoma macropomum EMPACADO AL VACÍO

Some lactic acid bacteria genera (BAL) as Lactobacillus, Leuconostoc, Lactococcus or their antimicrobial products as bacteriocins are used as alternatives biopreservation of minimally processed foods kept under refrigeration. Potential Biopreservatives from a bacteriocin producer native strain, Lactobacillus plantarum LPBM10, was evaluated on fillets of cachama hybrid Piaractus brachypomus x Colossoma macropomum, vacuum-packed and stored at 30±0,5°C during 30 days. The evaluation was undertaken using three treatments, bacteriocins raw extract, lactic acid and control. There were not differences among treatments on Mesophylls count. Meanwhile, psychotrophylls count reached values for fillets treated with raw extract of bacteriocins, lactic acid and control, 5.2 cycles log, 6.7 cycles log and 6.4 cycles log (P
