During this study, we characterized the seasonality's impact and environmental conditions on the yeast diversity from raw camel's milk collected in Algeria. The yeast counts were estimated to 3.55 × 102 CFU mL−1, with a maximum of 6.3 × 102 CFU mL−1. The yeasts were categorized phenotypically by API 20C AUX, MALDI-TOF and genetically by sequencing 26S rDNA and ITS1-5.8S-ITS2. The rDNA sequencing approaches revealed 12 species including unusual ones such as Trichosporon asahii, Pichia fermentans, Millerozyma farinosa, Pichia galeiformis, Candida tartarivorans and Pichia manshurica. The most dominant species were T. asahii (23%), P. fermentans (19%) and Rhodotorula mucilaginosa (14%). The high occurrence and large diversity were registered in samples collected during the autumn season, in the semi-arid and arid highlands regions with 0.66 × 103 CFU mL−1 and 0.51 × 103 CFU mL−1, respectively. Interestingly, T. asahii, R. mucilaginosa, P. fermentans, C. parapsilosis and C. zeylanoides were detected during both spring and autumn. [ABSTRACT FROM AUTHOR] |
