Antimicrobial and Antioxidant Effects of a Forest Actinobacterium V-002 as New Producer of Spectinabilin, Undecylprodigiosin and Metacycloprodigiosin
The aim of the study is the research and identification of a Streptomyces strain as a new producer of spectinabilin, undecylprodigiosin and metacycloprodigiosin. Among 54 actinomycete isolates isolated from El-Ogbane forest soils in Algeria, only one isolate, designated V-002, was selected for its ability to produce prodigiosins. The selected strain was analysed for its ability to produce three different secondary metabolites as well as their biological activities. V-002 belongs to the Streptomyces genus and has significant antimicrobial and antioxidant activities. The taxonomic position of V-002 by 16S rRNA sequence analysis showed a similarity of 99.93% with Streptomyces lasiicapitis DSM 103124(T) and 98.96% with Streptomyces spectabilis DSM 40512(T). Fractionation of crude secondary metabolites produced by the strain using HPLC-MS revealed the presence of spectinabilin, undecylprodigiosin and metacycloprodigiosin, which demonstrated significant activity. Strain V-002 is considered a new producer of spectinabilin, undecylprodigiosin and metacycloprodigiosin with significant antimicrobial and antioxidant activity.
