“…When CAT activity decreased, the accumulation of hydrogen increased and catalase was inhibited. It is reported that the decrease of CAT activity and the increase of Cd concentration in some plants are responsible for the decrease of protein content after metal toxicity and oxidative stress 35 . In this study, the CAT activity of J1 and J77 increased with the increase of Cd concentration.…”

In this study, 0, 0.5, 1, 1.5, 2, 4, 6 and 8 mg·kg−1 of cadmium were added to the cultivation materials. In order to study the effects of different concentrations of Cd stress on J1 and J77, the contents of antioxidant enzymes, proline and malondialdehyde, Cd content, agronomic traits and yield of fruiting bodies of Agaricus brasiliensis were determined, and the nutritional components such as polysaccharide, triterpene, protein, total sugar and total amino acid were determined. The results showed that the physiological indexes of strain J1 and J77 changed regularly under different concentrations of Cd stress. J1 was a high absorption and low tolerance variety, while J77 was a low absorption and high tolerance variety. Low concentration of Cd promoted the growth of strain J1, and higher concentration of Cd promoted the growth of strain J77. The contents of protein and total amino acids in the two strains changed greatly, followed by polysaccharides, which indicated that Cd stress had the greatest impact on the three nutrients, and other nutrients were not sensitive to Cd stress.

“…The various mechanisms that lead to the reduction of chlorophyll in plants grown in contaminated soils are mentioned such as: 1) inhibition of the synthesis pathway and increased activity of chlorophyllase (Shakoor et al, 2014); 2) substitution of the central magnesium ion of chlorophyll by heavy metals, leading to the loss of chlorophyll (Sharma & Dubey, 2005); 3) free radicals produced from lipid peroxidation that attack pigments like chlorophyll and destroy them (Andrade et al, 2009); 4) prevention of the activity of the 5-aminolevonic acid dehydratase (ALAD) enzyme, reducing chlorophyll biosynthesis (Prasad and de Oliveira Freitas, 2003).The application of mycorrhizal fungi and biochar was able to mitigate the adverse impact of cobalt on chlorophyll a and b levels in corn plants. This is likely due to the improvement of nutrient absorption, speci cally magnesium and nitrogen, which are important components in chlorophyll biosynthesis (Rohani et al, 2019). As seen in Table 3, cobalt treatments signi cantly increased the electrolyte leakage (EC) in comparison to the control.…”

The effects of cobalt contamination on maize plant growth and the potential benefits of arbuscular mycorrhizal fungi (AMF) and biochar (B) as low-cost amendments for improving plant growth in metal-polluted soils were investigated in a pot experiment. The experiment evaluated the impact of Rhizophagous intraradices and biochar on maize plants grown under different cobalt concentrations (0, 60, and 120 ppm). A wide range of physiological parameters, including plant height, number of leaves, root and shoot fresh and dry weight, relative water content, electrolyte leakage, chlorophyll and carotenoid content, oxidative stress, cobalt distribution, and nutrient content, were analyzed. The results revealed that cobalt contamination had a negative impact on plant growth, reducing chlorophyll and carotenoid content, increasing oxidative stress, and elevating cobalt accumulation in the shoot while also decreasing nutrient content. However, Rhizophagous intraradices inoculation and biochar application were shown to be effective in reducing cobalt uptake in aerial parts, improving nutrient content, and reducing oxidative stress. This study highlights the potential of AMF and biochar as cost-effective amendments for improving maize growth and mitigating cobalt toxicity in contaminated soils.
