Refractory species has been incised with Bacillus subtilis (Pânek and Reinprecht, 2008), Bacillus licheniformis (Yildiz et al., 2012), and Bacillus polymyxa (Knuth and McCoy, 1962). The use of further genera has been reported by Rossell et al. (1973) and Schmidt and Dietrichs (1976), including Pseudomonas, Flavobacterium and Serratia, while Kurowski and Dunleavy (1976) identified Cytophaga johnsonii and Macken and Pickaver (1979) suggested Enterobacter cloacae as potential species for improving permeability. While log-pond storage (“ponding”) has long been a means of storage, it has also been found to promote degradation by bacteria such as Pseudomonas sp. and Staphylococcus sp. (Kobayashi et al., 1998).

Phenotypic resistance assays revealed that of the enterobacteria, seven isolates were resistant to one or more beta-lactams (3 Enterobacter cloacae, 1 Citrobacter freundii, 1 Cronobacter sakazakii, 1 Enterobacter aerogenes and 1 E. coli); 18 to quinolones (7 E. cloacae, 3 E. coli, 6 C. freundii, 1 C. sakazakii and 1 E. aerogenes); 13 to tetracycline (1 Klebsiella oxytoca, 2 E. aerogenes, 4 Serratia marcescens, 3 E. coli, 1 C. freundii, 1 Proteus mirabilis and 1 Serratia odorifera); six to chloramphenicol (2 E. coli, 1 E. cloacae, 2 C. freundii and 1 S. marcescens); and two to trimethoprim-sulfamethoxazole (E. coli). Among these, 31% (eleven strains) presented resistance to two or more classes of antimicrobials. Notably, the isolates that showed intermediate resistance were interpreted as resistant and included in the PCR reactions to investigate resistance genes (Table 6).
