SUBSTÂNCIAS ANTIMICROBIANAS PRODUZIDAS POR Bacillus spp. ISOLADOS DE FRUTAS

Abstract

ANTIMICROBIAL SUBSTANCES PRODUCED BY Bacillus spp. ISOLATED FROM FRUITSThe present work aimed to investigate the production of a new antimicrobial substances by Bacillus sp. isolated from fruit, and verify its potential as a pathogen inhibitor associated to deterioration and food disease transmission, such as fungus and Gram-positive and Gram-negative bacteria. Ten strains were submitted to Gram stain and showed to be bacilli. These strains were tested for production of antimicrobial substances, using as indicators different Gram-positive bacteria. Three strains, named Ame3, Mam1 and Pes1 presented the largest spectrum of action against Gram-positive bacteria, suggesting that the substances produced by these strains may have some potential application as food biopreservative. KEY-WORDS: Bacillus sp.; FOOD BIOPRESERVATIVE; ANTIMICROBIAL SUBSTANCES.

Anti-Staphylococcal and Antifungal Substances Produced By Endospore-Forming Bacilli

“…These results are presented in Table 2. Oliveira et al, 2011). Table. 2: Inhibition of Staphylococcus sp.…”

“…The bacilli producer strains Pes1, Ame3 and Mam2 were obtained from peach, plum and papaya samples, respectively, purchased at markets and fairs distributed in different locations around the city of Rio de Janeiro, Brazil (Oliveira et al, 2011). Staphylococcal strains isolated from food used as indicators were obtained in previous works performed by our group (Junqueira et al, 2009;Oliveira et al, 2009).…”

“…These strains were tested for production of antimicrobial substances, using as indicators different Gram-positive bacteria. Three strains, named Ame3, Mam2 and Pes1 presented the largest spectrum of action against Gram-positive bacteria, inhibiting inclusive, different Bacillus and Staphylococcus reference strains (ATCC), suggesting that the substances produced by these bacilli may have some potential application as food biopreservative (Oliveira et al, 2011).…”
