The aim of this study was to characterize the microbial diversity contaminating plant leaves used as food packaging. In total, two hundred and forty (240) samples composed of Thaumatococcus daniellii and Musa paradisiaca leaves were collected and analyzed. Microbial diversity was assessed using specific medium and biochemical tests. The resistance profile was determined by the Müeller-Hinton agar diffusion method. The resistance (blaSHV, blaIMP, blaTEM) and biofilm formation (pslA, pelA) genes were searched by PCR method. Plant leaves were contaminated by bacterial (68.7%) and fungal (100%) strains. Extreme bacterial (7.1 log10 cfu/cm2) and fungal (3.5 log10 cfu/cm2) loads were obtained on Thaumatococcus daniellii leaves. Bacterial prevalence was 45.1% (S. aureus), 38.8% (E. coli) and 16.1 (P. aeruginosa). In order of decreasing importance, the prevalence of fungal species was 41.1% (A. flavus), 33.1% (A. fumigattus), 13.7% (A. niger) and 12.1% Candida sp. Resistance of E. coli to penicillins ranges from 31.6% to 87.3% and to cephalosporins from 13.3% to 28%. The P. aeruginosa strains were mainly resistant to aztreonam (87.6%). Those of S. aureus showed resistance to tetracycline (67.6), vancomycin (53), erythromycin (44.6) and levofloxacin (32.7). The blaSHV (14.28% to 18.60%) and blaIMP (9.52% to 16.28%) genes were detected in the bacterial strains. P. aeruginosa strains (19.05%) harbored the pslA and pelA genes. The health safety of these biodegradable plant-based packaging contributes to their valorization.展开更多

[Method] Based on the diversity of mitochondria DNA intron sequence among different varieties of M. paradisaca,an intron of cytochrome oxidase subunit II gene in mitochondria DNA genome was amplified and sequenced. And then the cluster analysis was used to classify 16 varieties of M. paradisaca,which belonged to five genotypes （AAA,AA,AAB,ABB and BB）. [Result] The 16 varieties of M. paradisaca could be divided to three classes：the first class contained one variety,the genotype of which was BB; the second class contained seven varieties,the genotype of which was ABB; the third class contained eight varieties,the genotypes of which included AA,AAA,AAB and BB. The new varieties YiXian 1,2 and 3 showed the nearest relationship with FenZa. [Conclusion] The result of classification was consistent with the genotypes,thus verified the feasibility and effectiveness of the new method in the genetic relationship identification of M. paradisaca germplasm.展开更多
