To obtain lead-resistant microorganisms as potential strains for bioremediation, in this study, a strain of fungus with high resistance to lead was isolated and domesticated from lead-contaminated soil, which cultured molecularly biologically identified the genus Sarocladium Pb-9 (GenBank No. MK372219). The optimal incubation time 96 h, temperature 25 °C, pH 7. had good adsorption effect on Pb2+ at concentration 2000 mg/L; scanning electron microscopy (SEM) observed that spores appeared be wrinkled deformed under stress, XRD analysis showed mycelium adsorbed Pb2+; Fourier transform infrared spectroscopy (FTIR) might produce substances such esters polysaccharides treatment different concentrations. above results has capacity lead. Therefore, it application value bioremediation environmental heavy metal pollution, study provides fundamental basis pollution environment.

Excessive utilization of chemical fertilizers degrades the quality medicinal plants and soil. Bio-organic (BOFs) including microbial inoculants microalgae have garnered considerable attention as potential substitutes for fertilizer to enhance yield. In this study, a field experiment was conducted investigate effects BOF partially substituting on growth plant Polygala tenuifolia. The parameters, bioactive component contents, soil properties composition rhizosphere microorganisms were measured. results indicated that 40% with showed most pronounced growth-promoting effect, leading 29.30% increase in underground biomass 19.72% 3,6'-disinapoylsucrose (DISS) content. Substituting 20% improved quality, significantly increasing organic matter content by 15.68% (p<0.05). Microalgae addition affected bacterial community P. tenuifolia, reducing relative abundance Cladosporium 33.33% 57.93%, while Chloroflexi 31.06% 38.27%, under reduction, respectively. positively correlated both DISS (p<0.05), indicating may stimulate species associated carbon cycling, thereby enhancing fertility, nutrient absorption, ultimately increased accumulation production components addition, there no significant difference contents between reduced dosage combined solid inoculant (SMI) polyglutamic (PMI), compared 100% fertilizer. Correlation analysis revealed PMI could phosphorus availability through Streptomyces recruitment. conclusion, our findings demonstrated bio-organic can substitute improve microorganisms, This provides theoretical basis productivity reduction.
