There are two aspects on the interaction of plants and heavy metals: 1. Common responses of plants to metal poisoning are the inhibition of growth, chlorosis and necrosis at the leaves, decreased photosynthesis, and even death. A green-house experiment was conducted to investigate the efficiency of three heavy metal-tolerant plant growth promoting bacterial strains (HMT-PGPB) (Alcaligenes faecalis MG257493.1, Bacillus cereus MG257494.1 and Alcaligenes faecalis MG966440.1 to alleviate the heavy metal’s toxic effects on sorghum plant (Sorghum bicolor, L.) in addition to their ability to enhance plant growth.

CRC Press, Boca Raton, pp 75–94. The second bioreactor is capable of taking in Martian regolith and extracting enhanced iron ores from it via biological processes. Heavy metals at toxic levels interact with cellular molecules, leading towards the unnecessary generation of reactive oxygen species (ROS), restricting productivity and growth of the plants. Microscopic analysis of M leaves showed a lack of dysfunctions in mesophyll cells exposed to TMs. Metal-hyperaccumulators are good candidates for phytomining due to their extraordinary capacity for Ni accumulation.

The doses of 0, 5, 10, 20, and 40 ppm were used. Application of GB on plants under HMs stress successfully improves growth, photosynthesis, antioxidant enzymes activities, nutrients uptake, and minimizes excessive heavy metal uptake and oxidative stress.
