“…Free living fungi are also able to increase nutrient availability. A strain of Trichoderma harzianum (Altomare et al, 1999), and other fungi such as Trichosporon beigelii , Phichia norvegensis , Cryptococcus albidus var aerius , as well as Penicillium bilaii (Kucey, 1987; Cunningham and Kuiack, 1992; Gizaw et al, 2017) have shown inorganic phosphate and other mineral solubilization capabilities. In our results, we observed that many of the 50 most abundant rhizospheric fungal OTUs were related to Phoma , Fusarium , Penicillium , Eupenicillium , and Trichoderma species (Supplementary Table S3).…”

Manipulating the plant-root microbiota has the potential to reduce plant stress and promote their growth and production in harsh conditions. Community composition and activity of plant-roots microbiota can be either beneficial or deleterious to plant health. Shifting this equilibrium could then strongly affect plant productivity in anthropized areas. In this study, we tested whether repeated bioaugmentation with Proteobacteria influenced plant productivity and the microbial communities associated with the rhizosphere of four plant species growing in sediments contaminated with petroleum hydrocarbons (PHCs). A mesocosm experiment was performed in randomized block design with two factors: (1) presence or absence of four plants species collected from a sedimentation basin of a former petrochemical plant, and (2) bioaugmentation or not with a bacterial consortium composed of ten isolates of Proteobacteria. Plants were grown in a greenhouse over 4 months. MiSeq amplicon sequencing, targeting the bacterial 16S rRNA gene and the fungal ITS, was used to assess microbial community structures of sediments from planted or unplanted microcosms. Our results showed that while bioaugmentation caused a significant shift in microbial communities, presence of plant and their species identity had a stronger influence on the structure of the microbiome in PHCs contaminated sediments. The outcome of this study provides knowledge on the diversity and behavior of rhizosphere microbes associated with indigenous plants following repeated bioaugmentation, underlining the importance of plant selection in order to facilitate their efficient management, in order to accelerate processes of land reclamation.

“…Among the fungi, Aspergillus sp., Penicillium sp. and Schwanniomyces occidentalis are considered to be the predominant members that convert insoluble inorganic phosphate in soil into soluble plant-usable forms (Gizaw et al 2017;Alori et al 2017). Earlier, culture-dependent approaches revealed that Bacillus subtilis and Aspergillus niger were most dominant in P-de cient acidic soils under tea cultivation (Bhattacharyya and Sarmah 2018).…”

We employed an Illumina-based high throughput metagenomics sequencing approach to unveil the overall rhizospheric as well as endophytic microbial community associated with an organically grown Camellia population located at the Experimental Tea Garden, Assam Agricultural University, Assam (India). Quality control (i.e. adapter trimming and duplicate removal) followed by de novo assembly revealed the tea endophytic metagenome to contain 24,231 contigs (total 7,771,089 base pairs with an average length of 321 bps) while tea rhizospheric soil metagenome contained 261,965 sequences (total 230537174 base pairs, average length 846). The most prominent rhizobacteria belonged to the genus viz., Bacillus (10.34%), Candidatus Koribacter (8.0%), Candidatus Solibacter (6.35%), Burkholderia (5.18%), Acidobacterium (4.08%), Pseudomonas (3.9%), Streptomyces (3.52%), Bradyrhizobium (2.76%) and Enterobacter (2.56%); while the endosphere was dominated by bacterial genus viz., Serratia (42.3%), Methylobacterium (7.6%), Yersinia (5.4%), Burkholderia (2.2%) etc. The presence of few agronomically important bacterial genuses such as Bradyrhizobium (1.18%), Rhizobium (0.8%), Sinorhizobium (0.34%), Azorhizobium and Flavobacterium (0.17% each) were also detected in the endosphere. KEGG pathway mapping highlighted the presence of microbial metabolite pathway genes related to tyrosine metabolism, tryptophan metabolism, glyoxylate and dicarboxylate metabolism and amino sugar metabolism which play important roles in endophytic activities including survival, growth promotion and host adaptation.

Phosphorous (P) is a nonrenewable and one of the most important macronutrients for all living organisms. The formation of complexes with cations such as Al, Fe, and Ca reduces the solubility of P leading to limiting the absorption of P by plants. Therefore, we need to apply excessive amounts of P through conventional fertilizers. However, plants can use only a small portion of P of these added fertilizers whenever those become unavailable. Therefore, utilizing excess amounts of phosphate as fertilizers can lead to various environmental issues like eutrophication. Phosphate-solubilizing microorganisms (PSM) have the ability to solubilize soil phosphate through the production of organic acids, inorganic acids, enzymes, protons, siderophores, and exopolysaccharides resulting in the absorption of P by plants. The application of PSM has the potential to be used as an efficient, eco-friendly, and sustainable approach that can replace traditional fertilizers. This review aimed to give an overview of the diversity of PSM, methods of P solubilization, current trends, and technological advances that can assist in using PSM to achieve Sustainable Development Goals (SDGs).
