Some fungal isolates affect soil by solubilizing nutrients and promoting plant growth; however, little is known about the effects of applications of these isolates on soil biology and fertility. Thus, the aim of the present study was to identify the effect of five well-known fungal endophytes, namely, Beauveria bassiana, Trichoderma asperellum, Metarhizium anisopliae, Purpureocillium lilacinum and Pochonia chlamydosporia on plant growth and the biological and chemical properties of the rhizosphere soil under Phaseolus vulgaris L. Spore suspensions from each of the five fungal isolates and three consortia (T. asperellum/P. lilacinum; B. bassiana/M. anisopliae; and a consortium of all five species) were applied to seeds, soil and shoots of common bean plants in a greenhouse assay. All fungal treatments resulted in greater root colonization by arbuscular mycorrhizal fungi (53.6% of root length in control and 66.6%–77.0% in the remaining treatments), concentration of rhizosphere soil magnesium (10%–33% higher than the control) and base saturation of cation exchange capacity (48.5% in control and 50.7%–55.1% in all other treatments). Applications of B. bassiana/M. anisopliae and of the consortium of five fungal isolates increased fluorescein diacetate hydrolysis (FDA) by 63% and 72% respectively, relative to the control. β-Glucosidase activity was lower in the applications of T. asperellum (20% lower), P. chlamydosporia (15% lower) and B. bassiana/M. anisopliae (18% lower) than in the control. Acid phosphatase was lower in the M. anisopliae (29%), P. chlamydosporia (22%) and T. asperellum/P. lilacinum (21%) and B. bassiana/M. anisopliae consortia (27%) treatments. Some fungal isolate applications stimulated shoot accumulations of N, P, B, Cu, Fe, Mn and Zn (mass). Applications of B. bassiana, T. asperellum, M. anisopliae, P. chlamydosporia and the consortium of five fungal isolates resulted in higher root dry mass relative to the control, while treatments of P. lilacinum, the B. bassiana/M. anisopliae consortium and the five fungal isolates resulted in higher dry shoot weight. Arylsulfatase activity and phosphate solubilizing fungi were not affected by the treatments. The values of the rhizosphere soil chemical and biological, accumulated nutrient mass and plant growth variables were highest in the (A) five fungi consortium, followed, in descending order, by (B) the B. bassiana/M. anisopliae consortium; (C) T. asperellum, B. bassiana and M. anisopliae; and (D) the T. asperellum/P. lilacinum consortium, P. lilacinum and P. chlamydosporia. These findings may benefit sustainable agricultural management systems that use fungal isolate treatments to eliminate or reduce the environmental impacts of mineral fertilizers and pesticides.

一些真菌分离物通过增溶养分和促进植物生长来影响土壤。然而，关于这些分离物的应用对土壤生物学和肥力的影响知之甚少。因此，本研究的目的是确定五个公知内生真菌，即，效果白僵菌，棘孢木霉，金龟子绿僵菌，Purpureocillium lilacinum和Pochonia chlamydosporia对植物的生长和根际土壤的生物和化学性质根据菜豆悬浮液从五个真菌分离物和三个财团（T. asperellum / P。lilacinum ;B.bassiana / M。各向异性; 以及由所有五个物种组成的联盟）通过温室测定法应用于普通豆类植物的种子，土壤和枝条。所有真菌处理均导致丛枝菌根真菌（在对照组中根长为53.6％，在其余处理中为根长的66.6％–77.0％），根际土壤镁的浓度（比对照高10％–33％）和根系上增加了根部定植。阳离子交换容量的饱和度（对照中为48.5％，其他所有处理中为50.7％-55.1％）。相对于对照，应用B. bassiana / M. anisopliae和五个真菌分离物的联合体可使荧光素二乙酸酯水解（FDA）分别增加63％和72％。β-葡萄糖苷酶活性在曲霉菌的应用中较低（降低20％），衣原体假单胞菌（降低15％）和B. bassiana / M. anisopliae（降低18％）。酸性磷酸酶是在较低的绿僵菌（29％），P. chlamydosporia（22％）和T.棘孢/ P。紫丁香（21％）和球芽孢杆菌/异种分枝杆菌联合体（27％）的治疗方法。某些真菌分离物的施用刺激了N，P，B，Cu，Fe，Mn和Zn（质量）的枝条积累。应用白僵菌，T.棘孢，绿僵菌，P. chlamydosporia和五个真菌分离财团导致根干质量相对于对照高，而治疗P. lilacinum，该球孢白僵菌/绿僵菌财团和五个真菌分离导致更高的干苗重。处理不影响芳基硫酸酯酶活性和溶解磷酸盐的真菌。根际土壤化学和生物学值，累积养分质量和植物生长变量的值在（A）五个真菌联盟中最高，其次是（B）球孢杆菌/ M。anisopliae财团；（C）T. asperellum，B. bassiana和M. anisopliae；（D）曲霉。紫丁香花财团，紫丁香花和衣原体。这些发现可能有益于可持续的农业管理系统，该系统使用真菌分离处理来消除或减少矿物肥料和杀虫剂对环境的影响。
