硅酸盐细菌的分离、鉴定及其生物学特性研究
Isolation, Identification and Biological Characterization of Silicate Bacteria
摘要
Abstract
Eight potassium-releasing strains were isolated from 288 soil samples collected from China by using the selective medium for silicate bacteria and identified into Bacillus mucilaginosus based on their morphological,physiological and biochemical properties and 16S rDNA sequences.Based on the analysis of soluble potassium by flame photometer among the 8 strains,the strains K1 and K3 could increase the potassium content in the liquid medium by 48.10% and 56.57% compared with control.In pot experiment,after 25 days K1 could increase the root length,plant height,leaf width and fresh weight of corn seedling by 42.91%,18.88%,9.11% and 116.73%,and K3 could increase the correspondents by 72.51%,22.81%,14.06% and 198.51% compared with the control.关键词
