With 45 endophytic fungi with the ability to resist heavy metal lead and zinc isolated from the dominant plants of Typhaorientalis presl, Melia azedarach, Boehmeria nivea and Ricinus communis in the Fankou lead and zinc mine wasteland in northern Guangdong as the research target, 30 iron producing carrier strains, 3 phosphorus solubilizing strains and 18 indoleacetic acid (IAA) producing strains, all with the ability to promote plant growth, are screened by using CAS detection solution color reaction, molybdenum antimony resistance colorimetry and Salkowski method, followed by a selection of the isolates with strong ability of producing iron carrier, dissolving phosphorus or producing indole acetic acid (IAA) as representative isolates for identification of morphological and ITS sequence analysis. The identification results show that WB-21 is under the category of Aspergillus, BM3 Cochliobolus, BM5 Alternaria, XP3.21 Colletotrichum, and ZMP5-3 Talaromyces respectively.
