Twenty-three strains of lactic acid bacteria were tested by deferred antagonism methods for bacteriocin-like activity against types A and B spores from 11 proteolytic and nonproteolytic Clostridium botulinum strains. Pediococcus pentosaceus ATCC 43200, Pediococcus pentosaceus ATCC 43201, Lactococcus lactis subsp. lactis ATCC 11454, Lactobacillus acidophilus N2, Lactobacillus plantarum Lb75, Lactobacillus plantarum Lb592, and Lactobacillus plantarum BN exhibited bacteriocin-like inhibition of all C. botulinum strains tested. By excluding inhibition due to hydrogen peroxide, acid, and lytic phage and confirming their proteinaceous nature, the inhibitors were confirmed as bacteriocins. The minimum inhibitory cell concentrations (MICC) required to produce 1 mm radius inhibition zones were determined by direct antagonism testing. Only strains 43200, 43201, 11454, and N2 were inhibitory when cultured simultaneously with the botulinal spores. The MICCs of strains antagonistic to C. botulinum spores by simultaneous testing ranged between 1.6 × 105and 4.7 × 107CFU/ml. Based on the MICCs, P. pentosaceus 43200 was most inhibitory to C. botulinum.

Sugarcane silage can be used in animal production systems; however, it is important to apply additives to improve its chemical composition and fermentative quality. We evaluated the effect of chemical (urea and calcium oxide (CaO)) and microbial (Lactobacillus buchneri (LB), Lactobacillus plantarum, Pediococcus pentosaceus, and Propionibacterium acidipropionici) additives on chemical composition, fermentation profile, microorganism population, and production of ethanol and other volatile organic compounds in sugarcane silage. Treatments studied were silage without inoculant (SS), SS with LB, SS with Lactobacillus plantarum and Pediococcus pentosaceus, SS with Lactobacillus plantarum and Propionibacterium acidipropionici, SS with 5 g CaO/kg fresh material (FM) (5CaO), SS with 10 g CaO/kg FM (10CaO), SS with 5 g urea/kg FM (5urea), and SS with 10 g urea/kg FM (10urea). The highest crude protein content (P = 0.001) and the lowest N-linked to fibre content (P = 0.001) occurred when applying urea. None of the treatments reduced the presence of yeast (P = 0.054), but a trend was detected of treatments based on CaO as promising in this Control. The silages treated with CaO had lower ethyl ester and ethanol (average for CaO-based treatments of 0.012 g/kg dry matter and 0.695 g/kg dry matter, respectively), and silages treated with 10urea had less acetone (P = 0.001) and methanol (P = 0.001). The sugarcane silages treated with chemical additive CaO reduced ethanol production and ester formation. There was a high correlation (r = 0.984) between ethyl acetate + ethyl lactate and ethanol contents.

La resistencia de microorganismos patógenos a los antibióticos y la posibilidad de residuos de antibióticos en los productos de origen animal provocan una atención creciente, siendo necesario el uso de alternativas potenciales como bacterias benéficas con carácter probiótico para reemplazar los antibióticos en la dieta de los animales. La metodología fue el aislamiento de bacterias ácido lácticas del tracto gastro intestinal de un lechón lactante, seguidamente se realizó la purificación bacteriana en medio de cultivo MRS, extracción de ADN, y en base de las secuencias del 16S ADNr fue amplificado por PCR con iniciadores universales. En el análisis bioinformático por el algoritmo de BLAST del National Center for Biotechnology Information se identificaron molecularmente, Lactobacillus farcimenis, Weissella sp, en el estómago; Lactobacillus brevis, Pediococcus pentosaceus, en el intestino delgado y en el intestino grueso, Pedio-coccus pentosaceus y Lactobacillus plantarum. En conclusión, existe una diversidad de Lactobacillus en el tracto gastrointestal del porcino, siendo un gran potencial como alternativa a los antibióticos en la alimentación y la inmunomodulación del sistema inmune del animal.

Barley Silage

Microbial inoculants are applied to forage at the time of ensiling to accelerate the decline of pH during the initial stage of silage fermentation, to preserve plant carbohydrates through homofermentation, and to preserve plant protein by decreasing proteolysis and deamination. Thus, inoculated silages are expected to improve animal performance. Whole crop barley has a low buffering capacity and abundant fermentable carbohydrates and is considered relatively easy to ensile. Results of previous experiments indicated that lactic acid bacteria-based inoculants have the potential to improve the ensilage of whole crop barley (Kung and Ranjit, 2001). The objective of the present study was to determine the chemical composition and in situ dry matter degradability of whole crop barley silage treated with one of two different types of inoculants (Lactobacillus plantarum or mixed with Pediococcus pentosaceus plus propionbacter freudenreichii as provide 1×105 CFU of lactic acid producing bacteria plus 1×104 CFU propionbacterium per g of DM).

El objetivo fue evaluar fechas de corte y del uso de aditivos sobre la calidad del ensilado de la planta entera de girasol. La variedad forrajera (Rumbosol-91) se cosechó en las semanas 1, 3 y 5 post-floración (F1, F2 y F3, respectivamente) y tratada con los siguientes aditivos: 1) 1.5 × 105 ufc de inoculante g-1 de forraje, a base de bacterias lácticas homofermentativas Enterococcus faecium, Pediococcus pentosaceus y Lactobacillus plantarum (INOC), 2) 3 ml kg-1 de forraje de una solución al 85% de ácido fórmico (FORM) y 3) sin aditivo (Testigo); siguiendo un diseño factorial 3x3 con cinco repeticiones. La producción de efluente y las pérdidas totales de materia seca (MS) se redujeron, desde 282 y 134 g kg-1 en F+1 hasta 96 y 87 g kg-1 en F+5 como resultado del alto contenido de humedad del forraje próxima a la floración. El análisis NIRS de las muestras de ensilaje mostró que los contenidos de proteína, fibra y digestibilidad descendían significativamente con la madurez de la planta; la rápida acumulación de aceite en la MS hizo que la concentración energética fuese superior en el estado fenológico más avanzado. La calidad fermentativa de los ensilajes fue satisfactoria, independientemente del momento de corte y del uso de aditivo. Se concluye que es preferible el corte de la planta a las cinco semanas post-floración, donde se espera una fermentación aceptable sin necesidad de conservantes.

Foram objetivos do presente estudo avaliar os efeitos da inoculação microbiana da silagem de alfafa sobre a digestibilidade total em carneiros. Doze carneiros machos e castrados foram distribuídos em um delineamento inteiramente casualizado e os tratamentos corresponderam a silagem pré-secada de alfafa (média de 35,7% de MS e 19,6% de PB) controle ou inoculada com o produto Silobac (Lactobacillus plantarum e Pediococcus pentosaceus). O experimento teve duração total de 21 dias, sendo os cinco últimos destinados à coleta de fezes e urina. A inoculação aumentou a digestibilidade total da MS (inoculado = 62,5% vs. controle = 59,5%), dos ENN (70,9% vs. 65,7%), da FDN (53,8% vs. 48,8%), da FDA (52,5% vs. 44,7%), do amido (84,0% vs. 80,2%), o NDT (59,5% vs. 56,7%) e o consumo de MS (2,82 vs. 2,48% do PV), mas não alterou a digestibilidade total da PB (73,9% vs. 73,2%), EE (50,7% vs. 54,3%), FB (47,1% vs. 43,9%) ou a retenção nitrogenada (3,27 vs. 2,86 g de N/animal/dia).
