Project description:The aim of this work was to unveil the molecular mechanisms by which Streptomyces respond to a ROS intracellular imbalance and the effect of such response on the biosynthesis of secondary metabolites. The study was focused on the industrial actinomycete S. natalensis ATCC 27448 producer of the polyene pimaricin - an antifungal agent widely used in the food industry and promising for antiviral activity and stimulation of immune response. Two-color microarray with common reference. The transcriptomes of S. natalensis ATCC 27448 (wild-type), S. natalensis CAM.02 (DsodF) and S. natalensis CAM.04 (DahpCD) were compared. Two time points were included: late exponential (T1) and early stationay (T2) phase. Biological triplicates were performed for each strain/time point. Genomic DNA of S. natalensis ATCC 27448 was used as common reference.

Project description:To characterize the differentially expressed genes between adding fungal elicitor and without fungal elicitor on Streptomyces natalensis HW-2
Project description:The objective was to analyze the differential expression between the wild strain and the Streptomyces clavuligerus ΔclaR::aac mutant Six experimental conditions were assayed, two strains (Streptomyces clavuligerus ATCC 27064, S. clavuligerus ΔclaR::aac) in three culture times (22.5h, 46.5h and 60 h). Two biological replicates for each condition.
