Assessing the Potential of the Terrestrial Cyanobacterium Anabaena minutissima for Controlling Botrytis cinerea on Tomato Fruits

Cyanobacteria are oxygenic phototrophs that have an essential role in soil N2 fixation, fertility, and water retention. also natural sources of bioactive metabolites beneficial to improve plant vigor potentially active against fungal pathogens. Therefore, we studied the antifungal activity extract (WE) phycobiliproteins (PBPs) from Anabaena minutissima strain BEA 0300B pathogen Botrytis cinerea on tomato fruits vitro. The PBPs were characterized by using FT-IR FT-Raman spectroscopies. Both (5 mg/mL) (ranged 0.3 4.8 reduced disease incidence severity mycelium growth colony forming units For growth, a linear PBP dose-response was found. Tomato spectroscopies order evaluate structural modifications induced treatment. preserved cutin pectin structures challenge. In conclusion, A. can be considered potential tool for future large-scale experiments control.
