The present study aims to isolate Lactobacillus species from locally fermented vegetables and to characterize selected isolates for their probiotic potential. Seventeen Lactobacillus strains (9 Lactobacillus plantarum 1, 3 Lactobacillus pentosus, 2 Lactobacillus brevis 1, 2 Lactobacillus brevis 3 and 1 Lactobacillus salivarius) were isolated and tested for their probiotic potential. This included survival in gastrointestinal simulated juice, antagonistic activity against Salmonella typhimurium, Escherichia coli, Bacillus cereus and a methicillin-resistant Staphylococcus aureus (MRSA) isolate, bile tolerance and antibiotic resistance to 8 antibiotics. Most isolates, especially Lactobacillus plantarum 1, were tolerant to the acidity and intestinal conditions after exposure for three and four hours, respectively, with reduction less than one log cycle of the starting CFU/ml. The same trend was observed in respect to bile tolerance with slight variations. All isolates inhibited the growth of the tested pathogens and were the most effective against MRSA isolate. As for antibiotic resistance, it was pronounced against kanamycin, ampicillin, erythromycin and tetracycline. Some isolates (M3, M5, M6, M12, B14) showed a resistance to 6 or more antibiotics of those tested. These results prove that the traditionally fermented vegetables are a good source for probiotic Lactobacillus. However, further in vivo studies are needed to substantiate the potential of these isolates.
This paper, whose title alludes to Joseph Massad’s article ‘Re-Orienting Desire: The Gay International and the Arab World’ (2002) aims at critically discussing his ideas. To do so, I mobilize Julia Kristeva and Luce Irigaray’s theorizations of sexual difference. Their understandings of becoming-subject will be put in conversation with a close reading of shame in Bareed Mista3ji: True Stories, as guided by Dina Georgis’ analysis, in order to engage with the hybrid and affective articulations of Arab (homo)sexualities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
