Researchers of the CAS South China Botanical Garden have isolated two indigenous mineralizing bacterial strains, Bacillus pasteurii and Bacillus cereus, from typical contaminated soils in northern Guangdong. They showed that under low-concentration contamination conditions (Cd: 0.5-4.0 mg/L, Pb: 100-200 mg/L), both indigenous strains achieved an immobilization efficiency of over 98% for both Cd and Pb, demonstrating high performance. Even under higher stress conditions (e.g., Cd at 8 mg/L), the indigenous B. pasteurii maintained an immobilization efficiency of 96%.
