Advances in Microbiology 2019年第6期9卷 525-540页

作者： ameni Telmoudi Imen Mahmoudi Mnasser Hassouna Unité de Recherche “Bioconservation et Valorisation des Produits Agro-alimentaires (UR 13AGR 02)” école Supérieure des Industries Alimentaires de Tunis (ESIAT) Tunis Tunisia

The present work focused on the effects of the Modified Atmosphere Packaging (MAP) 1 (5% O2 and 10% CO2) or 2 (2% O2 and 5% CO2) and the previous addition of Lactoperoxidase System (LPS) and Oregano essential oil or chlorine washing on the quality of fresh-cut lettuce during refrigerated storage at +4?C. Our results showed the significant effect of this combined treatment on quality improvement during storage. Thus, mesophilic bacteria was reduced in treated samples compared to those untreated with number which not exceeded the critical of 5 × 107 UFC?g-1 (p 2 and CO2 levels created by both atmosphere were not significantly different between the two treatments (p > 0.05). Brightness of lettuce samples was significantly reduced during storage. Thereafter, the PCA data showed the effect of combined treatment on the preservation of hygienic, physico-chemical and sensory quality up to the 7th day of refrigerated storage of these treated samples. The results obtained draw attention to modified atmosphere packaging lettuce and the addition of bio-preservatives which could be an alternative of choice to replace chlorine to preserve the sanitary quality of green products.

Drug Susceptibility Testing of Mycobacteria Isolated from Humans and Cattle from Selected Sites of Ethiopia

引用

Journal of Tuberculosis Research 2014年第3期2卷 125-131页

作者： Mekonnen Tadesse Gobena ameni Kassu Desta Aklilu Lemma Institute of Pathobiology Addis Ababa University Addis Ababa Ethiopia Department of Medical Laboratory Sciences Addis Ababa University Addis Ababa Ethiopia Mailman School of Public Health-ICAP in Ethiopia Columbia University Addis Ababa Ethiopia

Background: The effectiveness of a standard anti-tuberculosis (TB) treatment regimen correlates with in vitro drug susceptibility pattern of the infecting tubercle bacilli. The results of the drug susceptibility tests help select a proper treatment regimen or modify treatment regimen for a better management of patients and surveillance and timely control of the spread of the drug resistant TB in the community. Treatment of drug resistant TB is costly, and the outcomes, including survivorship, can be poor. As the result, the drug susceptibility test has become more important than ever. Objective: To determine the drug-susceptibility pattern of M. tuberculosis and M. bovis isolated from selected sites of Ethiopia. Methods: The conventional indirect Löwenstein-Jensen (L-J) proportion method was used to detect the drug susceptibility pattern of 29 isolates of M. tuberculosis and 21 isolates of M. bovis to four anti-TB drugs (streptomycin, rifampicin, isoniazid and ethambutol). Results: Resistance was observed only in M. tuberculosis isolates while all isolates of M. bovis were fully susceptible to the four drugs. Thus, the overall resistance of M. tubeculosis isolates to any of the four drugs was 51.7%. As such, any type of drug resistance was most frequent to streptomycin (41.3%) followed by isoniazid (20.6%) while it was minimal to rifampicin (6.8%) and ethambutol (3.4%). Multidrug resistant TB (MDR-TB) was not detected in the study. Conclusion: This preliminary study showed high level of resistance in M. tuberculosis isolates warranting appropriate use of anti-TB drugs in those sites from where the isolates were obtained.

Volatile Compounds Analysis of Tunisian Propolis and Its Antifungal Activity

In this study, four samples of Tunisian propolis were analyzed for their volatile compounds. Static Headspace technique coupled with gas chromatography-mass spectrometry (GC/MS) was used for the volatile profile characterization. Statistical investigation of the samples was made applying hierarchical clustering method, K-Means cluster and principal component analysis. Results showed that 47, 36, 30 and 24 different compounds were identified, respectively, in the samples from Zouarine, Zelligua, Bizerte and Beni Khalled. Propolis volatiles were dominated by monoterpene hydrocarbons. α-pinene was the major compound representing 81.14%, 82.67% and 90.74%, respectively, of the total propolis volatiles collected from Zelligua, Beni Khalled and Zouarine and only 45.22% of the sample from Bizerte which had a very different composition. The in vitro antifungal activity of the volatiles from all samples against Candida albicans was also assayed and reported.
