Campello Multidisciplinaria (Ciencias Naturales y Exactas) phosphate Glomeromycota Atlantic Forest Enterobacteriaceae soil microorganisms Communities of P-solubilizing bacteria, fungi and arbuscular mycorrhizal fungi, were evaluated in two differentecosystems. Samplings taken from two areas of Atlantic forest, in Paraty RJ, Brazil, one with asecondary forest and the other with a grass pasture were studied. Four growth media: GL (glucose and yeastextract), GES (glucose, soil extract, KNO3, CaCl2, MgSO4, NaCl, FeEDTA and micronutrients solution),GAGES (glucose, soil extract, arabinose, glycerol, CaCl2, MgSO4 and NaCl) and GELP (glucose, soil extract,yeast extract, peptone, CaCl2, MgSO4 and NaCl) were evaluated for the isolation of P-solubilizingmicroorganisms. The identification of P-solubilizing bacteria was based on 16 S rDNA sequence analysis,while the identification of P-solubilizing fungi and arbuscular mycorrhizal fungi was based on morphology.The greatest number of P-solubilizing bacteria was isolated using GL and GELP growth media. The greatestnumber of P-solubilizing fungi was isolated using GAGES and GES. The bacteria were identified as Enterobacteriaceaeand Bacillus sp., while the P-solubilizing fungi were identified as Aspergillus sp. Glomusmacrocarpum and Glomus etunicatum were the dominant mycorrhizal fungi in the secondary forest and grasspasture area, respectively. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778116 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.78 |
