Studies on mineral phosphate solubilization by cyanobacteria Westiellopsis and Anabaena

Roles of Phosphate Solubilizing Microorganisms from Managing Soil Phosphorus Deficiency to Mediating Biogeochemical P Cycle

“…In addition to these common heterotrophic PSM, autotrophic microorganisms with P i solubilizing abilities were also reported [ 65 ]. Yandigeri [ 81 ] evaluated the rock phosphate and tricalcium phosphate solubilizing abilities of two diazotrophic cyanobacteria, Westiellopsis prolifica , and Anabaena variabilis . Periodic monitoring showed that both cyanobacterial strains could significantly increase P t and available-P contents in medium in P-starved or insoluble-P cultures.…”

“…were previously reported to solubilize PR by producing Ca-chelators or siderophores [ 78 ]. In addition to organic acid secretion and H + dissolving mechanisms, P may be liberated from P i minerals by the synthesis of chelators (e.g., Ca, Al, and Fe-chelators) in PSB, PSA, and blue green algae ( Figure 2 ) [ 78 , 81 , 87 , 88 ]. Since PR and other primary P i minerals are mainly insoluble hydroxyapatite, or Ca, Al, and Fe/phosphate, the siderophores and chelators could form chelates with Ca, Al, and Fe, resulting in the release of P originally bound by these metals [ 81 ].…”

Role of Microorganisms in Plant Nutrition and Health

“…Kleiner and Harper (1977) reported that soils with cyanobacterial cover showed more extractable phosphates than in nearby soils without cover. The production of phthalic acid as a possible mode of P-solubilisation by cyanobacteria was proposed by Yandigeri et al (2011). Application of cyanobacteria to rice crop was investigated extensively even though their application to other crops has also been shown interest in recent years.…”

Cianobactérias: uma revisão sobre potencial nutricional e alguns aspectos biotecnológicos

“…A utilidade prática destes organismos como fonte de fixação biológica do nitrogênio em arrozais tem sido reconhecida. Existem porém poucos relatos sobre a sua capacidade de solubilizar fósforo mineral e outros minerais, importante atributo destas bactérias diazotróficas (YANDIGERI, MEENA, et al, 2011;YANDIGERI, YADAV, et al, 2011).…”

“…No entanto, o ferro é um dos mais importantes nutrientes químicos necessários para o crescimento de Chlorella sp. Nos últimos anos, a importância do ferro no crescimento da microalga foi estudada por muitos investigadores (BERMEJO et al, 2008;YANDIGERI, MEENA, et al, 2011;YANDIGERI, YADAV, et al, 2011).…”
