Kinetics of metal sulfide nanomaterials production by lithium-resistant isolates in presence of lithium and cysteine. A The auto-metallography reaction was evaluated on CdS and Li₂S nanoparticles synthesized by chemical methods [36]. The production of metal sulfide nanomaterials was monitored in B P. rhodesiae, C P. koreense, and D Pseudomonas sp. at 4, 16, and 24 h as previously reported [38,39,40,41,42,43]. The intracellular and extracellular presence of lithium sulfide nanoparticles was evaluated
