The MaMV-DC cyanophage,which infects the bloom-forming cyanobacterium Microcystis aeruginosa,was isolated from Lake Dianchi,Kunming,***-one cyanobacterial strains were used to detect the host range of *** aeruginosa FACHB-524 and plaque purification were used to isolate individual cyanophages,and culturing MaMV-DC with cyanobacteria allowed us to prepare purified cyanophages for further *** microscopy demonstrated that the negatively stained viral particles are tadpole-shaped with an icosahedral head approximately 70 nm in diameter and a contractile tail approximately 160 nm in *** one-step growth experiments,the latent period and burst size of MaMV-DC were estimated to be 24–48 hours and approximately 80infectious units per cell,*** endonuclease digestion and agarose gel electrophoresis were performed using purified MaMV-DC genomic DNA,and the genome size was estimated to be approximately 160 *** dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE)analysis revealed four major structural *** results support the growing interest in using freshwater cyanophages to control bloom-forming cyanobacterium.

与分担全纯函数相关的正规族

数学年刊（A辑） 2016年第1期37卷 89-96页

作者：李三华井冈山大学数理学院江西吉安343009

设F是在区域D内的一族亚纯函数,其零点重级至少为k,k是一个正整数,a(z)(≠0)在区域D内全纯.若对于任意的f∈F,有(1)f(z)与a(z)没有公共的零点;(2)f(z)=0f(k)(z)=a(z)■0<|f^((k+1))(z)-a'(x)|<|a(z)|,则F在D内正规.
