The invention relates to a strain of
Chryseobacterium sp. ZJUHULYY1 and application of the
Chryseobacterium sp. ZJUHULYY1 in promotion of corn growth and
iron absorption, and provides a strain of
Chryseobacterium sp. ZJUHULYY1, which is preserved in China Center for Type Culture Collection on April 27, 2025, and has a preservation number of CCTCC NO: M 2025904. The strain of
Chryseobacterium sp. ZJUHULYY1 is obtained by separating and purifying from
rhizosphere soil of corn, and the strain of
Chryseobacterium sp. ZJUHULYY1 is obtained by separating and purifying from
rhizosphere soil of corn. The biological characteristics of the strain are as follows: after being cultured in an LB plate culture medium at 30 DEG C for 24 hours, the
bacterial colony is round or oval, golden yellow, smooth and glossy in surface, neat in edge and negative in
gram staining; when the strain is inoculated to
rhizosphere of corn growing in
calcareous soil, compared with a control group, the
plant height,
chlorophyll content,
biomass and active
iron content of the corn are all remarkably improved, the growth condition of the corn in the
calcareous soil is effectively improved, and the absorption and utilization efficiency of the corn on iron elements is improved.
