“…Atomic absorption spectroscopy (AAS) was used to test the single heavy metal removal capacity of the screened resistant strains [27]. According to the previously reported methods, the heavy metal removal performance of resistant strains has been slightly changed [22]. The initially screened resistant strains were placed in MRS medium containing 60 mg/L of Cd 2+ , Pb 2+ , and Cr 6+ at an inoculum amount of 5% (v/v).…”

Due to industrial development, heavy metal pollution has become a severe global health hazard. The bioadsorption method represented by the adsorption of lactic acid bacteria (LAB) has been widely employed. The purpose of this study is to screen LAB strains that can remove cadmium, lead, and chromium. Through the heavy metal resistance tests, four strains with significant growth inhibition rate were identified. After 16S rDNA sequencing, these resistant strains were identified by Lactobacillus helveticus KD-3 (Cd2+ removal rate 37.54 ± 0.85%), Limosilactobacillus fermentum B27 (Pb2+ removal rate 69.41 ± 0.19%), Lacticaseibacillus rhamnosus 7469 (Cr6+ removal rate 71.13 ± 0.97%), and Lb. helveticus K5. Three encoding genes were identified in our screen strains, namely resistance gene czcD, chromium resistance gene chrA, and lead resistance gene pbrT. L.helveticus KD-3 exhibited the best comprehensive performance. Given the diverse types of heavy metal pollution at present, the current research mainly focuses on the removal of a single heavy metal by one strain. The four strains enrich the absorption resources of LAB for heavy metals, paving a new way for the biosorption of various heavy metals in food by LABs.

“…Therefore, trace heavy metal in TCM is dangerous to human health. In recent years, there have been many research studies focusing on the removal of heavy metals in simulated Chinese herbal medicines (CHMs), while less attention has been paid to the in situ removal of trace heavy metals from CHMs. − Therefore, it is of great importance to develop a highly active method for in situ removal of heavy metals from herbal water decoction.…”

A mesoporous carbon (PC-2) obtained by using sucrose as a carbon source and urea as a nitrogen source has been used to remove trace mercury (Hg) from honeysuckle water decoction with high efficiency. The morphology, chemical composition, and pore structure of PC-2 have been characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and Brunauer−Emmett−Teller (BET). The results show that the specific surface area of PC-2 with the −NH 2 functional is 1077.44 m 2 •g −1 , and the mesoporous pore size is mainly around 2.8 nm. The investigation of the relationship between the adsorption performance and the structure of PC-2 indicates that the pore size and the chemical composition of carbons are significantly correlated with adsorption performance of mercury in water and honeysuckle water decoction. PC-2 has high efficiency approximated 100% for mercury from aqueous solutions. The pseudo-second-order kinetic model and the Freundlich model could better fit the adsorption process of Hg(II) onto PC-2. The process was dominated by chemical adsorption. Meanwhile, the adsorption behavior and the influence on the medicinal components (chlorogenic acid) of mercury removal in honeysuckle water decoction were determined by high performance liquid chromatography (HPLC). Results suggest that PC-2 has high efficiency approximated 66% for mercury from honeysuckle water decoction under optimal adsorption conditions, without affecting its active ingredients (chlorogenic acid). Therefore, PC-2 can potentially be used for adsorption of mercury in honeysuckle water decoction.
