Summary: The study investigated the potential of B. cereus in ameliorating Cd-induced toxicity in mirror carp. Results showed that dietary supplementation with Zn-enriched B. cereus can reduce changes in intestinal microbiota composition in Cd exposure and decrease pathogenic bacteria. This suggests that Zn-enriched B. cereus has the potential to combat Cd toxicity in mirror carp by inhibiting alterations in bioaccumulation and antioxidant enzyme levels.

Summary: The study found that cadmium induced oxidative stress in Ulva compressa, which was mitigated by activating antioxidant enzymes and synthesizing glutathione and ascorbate. Calcium-dependent protein kinases, calmodulin-dependent protein kinases, calcineurin B-like protein kinases, and MAPKs are involved in cadmium accumulation and GSH and phytochelatin synthesis.

Summary: The study compared the effects of ascorbic acid (ASC) and glutathione (GSH) in alleviating copper (Cu) toxicity in rice, finding that ASC was more effective in restricting Cu2+ accumulation. ASC also better balanced Ca2+ and Mg2+, protected photosynthetic pigments, and activated antioxidant defense mechanisms compared to GSH.

Summary: The chromate resistant bacterium Bacillus cereus b-525k isolated from tannery effluents exhibited high tolerance to various toxic metal ions and showed efficient biosorption of chromium. The bacterium also showed significant production of antioxidant enzymes under chromate stress, alleviating oxidative damage. Pilot-scale experiments demonstrated that Bacillus cereus b-525k effectively removed chromium from tannery effluents, suggesting its potential application in chromate-contaminated sites.

Summary: This study provides new evidence of the successful use of metal oxide nanoparticles in the remediation of heavy metals. Zinc oxide nanoparticles (ZnO NP) and copper oxide nanoparticles (CuO NP) were found to alleviate cadmium (Cd) toxicity in Phaseolus vulgaris L. seedlings and plants. The physiological and metabolic parameters were monitored to elucidate the mechanism and process of Cd-induced phytotoxic effects on bean. The NP dose-dependent response of P. vulgaris seedlings and the differential response of growing plants in terms of length and biomass were observed. Both ZnO NP and CuO NP were able to reduce the hypergeneration of hydrogen peroxide (H2O2) and enhance ROS scavenging enzymatic capacity, while inhibiting the activity of ROS producing enzymes. The modulation of redox enzymes involved in cellular homeostasis and maintaining reduced status in cells was also observed. ZnO NP triggered more significant metabolic regulations allowing to mitigate the oxidative damage caused by Cd.

Summary: Cadmium (Cd) pollution is a threatening challenge to the environment and human health, with serious impacts on natural organisms. Green algae, such as Chlamydomonas reinhardtii (C. reinhardtii), have the potential to be a safer and more cost-effective approach for treating heavy metal ions in wastewater due to their sorption properties. However, C. reinhardtii is affected by heavy metal ions when sorbed. Melatonin can protect plants from damage under stress conditions. In this study, the effects of melatonin on C. reinhardtii under Cd stress were investigated, including cell morphology, chlorophyll content, enzymatic activity, gene expression, and the AsA-GSH cycle. The presence of melatonin effectively protected the activity of photosynthetic system II, enhanced antioxidant activity, upregulated gene expression in the AsA-GSH cycle, and reduced the level of ROS, alleviating the damage caused by Cd toxicity.

Summary: In real-field soil conditions, the co-occurrence of microplastics (MPs) and cadmium (Cd) is common and may pose potential risks to soil ecosystems. This study evaluated the effects of biodegradable MPs (PLA) and Cd on a soil animal Folsomia candida. The results showed that both single and combined PLA and Cd had negative influences on the survival, reproduction, and growth of F. candida, with the effects intensifying at higher PLA concentrations. However, combined PLA and Cd alleviated the toxicity of Cd at lower PLA concentrations. The study also suggested that MP treatment may be a promising biomarker for soil collembolan in assessing soil MP exposure.

Summary: In this study, it was found through a pot experiment that the endophyte Bacillus cereus G2 alleviated osmotic and oxidative stress in salt-stressed Glycyrrhiza uralensis by increasing the contents of proline, soluble sugar, and glycine betaine, as well as the activities of antioxidant enzymes and the ascorbate-glutathione cycle.

Summary: This study investigated the bioaccumulation, remediation, tolerance, and effects of manganese ions and copper ions on antioxidant enzymes of thermophilic Bacillus cereus SO-16. The results showed that Mn(II) was less toxic than Cu(II) to B. cereus SO-16, and the bacterium exhibited less tolerance to Mn(II) and Cu(II) ions in liquid medium compared to solid medium. The study also found that B. cereus SO-16 can be utilized in industrial wastewaters for the recovery and remediation of toxic metals.

Summary: Bacillus cereus is a common causative agent of food poisoning outbreaks and can produce biofilms, causing problems in the food industry. Enzymes have been used as an alternative approach to destroy biofilms and have been effective in the removal of B. cereus biofilms. However, more research is needed on the specific application of enzymatic biofilm removal in different strains of B. cereus.
