The invention relates to the field of microbial technology. Chinese holly endophyte is separated through an endophyte microbe isolation technology from a Chinese holly plant living body collected from Hangzhou, Zhejiang province, is identified through microorganism taxonomy as Streptomyces sioyaensis, and is named as Streptomyces sioyaensis 107. The bacterial strain has already been conserved in China General Microbiological Culture Collection Center on the conservation date of December 12th, 2012 and the conservation register number of CGMCC No.6984. The most significant feature of the preparation method is that the bacterial strain liquid is fermented to produce an active metabolite which has an inhibition action on plant fungal disease pathogenic bacteria like Rhizoctonia solani and Thanatephorus cucumeris and is an important agricultural microbial resource.

The invention discloses a synthesis method of hydrogenated nopyl-containing symmetric genini quaternary ammonium iron and antibacterial application. The synthesis method comprises the following steps:performing heating reflux on hydrogenated nopyl-containing tertiary amine and alpha-omega-dibromohaloalkane as raw materials in an organic solvent, and performing cooling, crystallization, filtering,washing and vacuum drying after reactions, so as to obtain seven types of hydrogenated nopyl-containing symmetric genini quaternary ammonium iron. When the mass concentration of a medicine liquid is500mg/L, the seven types of hydrogenated nopyl-containing symmetric genini quaternary ammonium iron have good inhibition functions on ten plant pathogenic fungi, particularly the inhibition rates uponfusarium proliferatum, alternaria kikuchiana, ceratosphaeria phyllostachydis, sphaeropsis sapinea and fusicoccum aesculi are greatly higher than that of chlorothalonil upon the plant pathogenic fungi, and the inhibition rates of the hydrogenated nopyl-containing symmetric genini quaternary ammonium iron upon thanatephorus cucumeris is equivalent to that of chlorothalonil.
