Identification of acetic acid bacteria isolated from Tunisian palm sap

Date palm sap (Phoenix dactylifera L.), called Lagmi, is a sugary substrate that readily ferments through the activity of native microflora that consists mainly of yeasts, lactic acid bacteria and acetic acid bacteria (AAB). The aim of this work was to perform a preliminary step in the isolation and identification of AAB species from different samples of palm sap collected in Southern Tunisia, in order to use them as a...

Evaluation of banana genotype resistant to Xanthomonas wilts disease (Xanthomonas campestris pv. musacearum) in south east of Ethiopia

Xanthomonas wilt caused by Xanthomonas campestris pv.musacearum (Xcm) is one of the most important constraints to banana production. The use of resistant banana varieties would be a long-term and cost-effective solution to control any pathogen. Therefore, identifying this pathogen resistant banana genotype is one of the basic requirements for effective management. The current study was therefore initiated to evaluate...

Comparative study for growth and sporulation of some mycotoxigenic fungi in relation to water activity effects

This study examined the effect of water activity (0.85-0.995 aw) on growth rate and asexual spore production for four mycotoxigenic strains (Aspergillus flavus, Aspergillus ochraceus, Aspergillus carbonarius and Penicillium verrucosum) on Malt Extract Agar (MEA). The water activity levels of MEA media were modified ionically (NaCl) and non-ionically (glycerol). Results showed that the optimum aw for growth was at...

Screening of Lactobacillus spp. from raw goat milk showing probiotic activities against pathogenic bacteria

This research work was executed to isolate potential Lactobacillus spp. from local raw goat milk samples for their antimicrobial activities against different human intestinal pathogens. Isolation of such bacteria was carried out by Man Rogosa Sharpe (MRS) agar media. Identification of the isolated strain was conducted according to the morphological and biochemical tests. Furthermore, growth optimization and their...

Association of N2-fixing cyanobacteria with wheat (Triticum vulgare L.) roots

Two locally prevailing hetyerocystous cyanobacterial isolates, collected from alluvial clay soil and identified as Nostoc muscorum and Anabaena variabilis, were tested (either singly or mixed) for their potency to colonize the roots of wheat seedlings. N. muscorum formed close association with root hairs, whereas A. variabilis showed loose binding. The mixture of both cyanobacterial strains formed weak association with...
