In present study in vitro phytopathogen suppression activity of siderophoregenic preparations of Ni and Mn resistant Alcaligenes sp. STC1 and Pseudomonas aeruginosa RZS3 SH-94B isolated from soil were found superior over the chemical pesticide. Siderophore rich culture broth and siderophore rich supernatant exerted antifungal activity against Aspergillus niger NCIM 1025, Aspergillus flavus NCIM 650, Fusarium oxysporum NCIM 1281, Alternaria alternata ARI 715, Cercospora arachichola, Metarhizium anisopliae NCIM 1311 and Pseudomonas solanacerum NCIM 5103. Siderophore rich broth and supernatant exhibited potent antifungal activity vis-à-vis oraganophosphorus chemical fungicide; kitazine. The minimum fungicidal concentration required was 25 μl for Aspergillus niger, Aspergillus flavus, Fusarium oxysporum, Cercospora arachichola, Metarhizium anisopliae, Pseudomonas solanacerum and 75 μl for A. alternata.
在本研究中,从土壤中分离出的耐镍和锰的产铁载体 Alcaligenes sp. STC1 和铜绿假单胞菌 RZS3 SH-94B 的产铁载体制剂的体外植物病原菌抑制活性优于化学农药。富含铁载体的培养液和富含铁载体的上清液对黑曲霉 NCIM 1025、黄曲霉 NCIM 650、尖孢镰刀菌 NCIM 1281、链格孢菌 ARI 715、瓜叶霜霉病菌、金龟子绿僵菌 NCIM 1311 和丁香假单胞菌 NCIM 5103 表现出抗真菌活性。富含铁载体的培养液和上清液对有机磷化学杀菌剂克百威表现出很强的抗真菌活性。黑曲霉、黄曲霉、尖孢镰刀菌、瓜叶霜霉病菌、金龟子绿僵菌和丁香假单胞菌所需的最低抑菌浓度为 25μl,而链格孢菌所需的最低抑菌浓度为 75μl。
