“…Similarly, Amin et al [54] observed an increase in the Cu content in plants (Abelmoschus esculentus, Avena sativa, Guizotia abyssinica, and Glycine max) to a dose of 300 mg Cu kg −1 . There are a number of studies confirming that plant roots are the first organ in which the excess of harmful metals is sequestered [33,50,55,56]. This is especially the case for non-hyperaccumulator plants.…”

The aim of the investigation was to evaluate the response of plants, using black mustard (Brassica nigra L. Koch) as a model plant, to soil contamination with copper (0, 200, 400, 600 mg Cu kg−1 of soil), and to determine the effectiveness of the Cu immobilization with mineral neutralizing materials, such as lime, clay and zeolite. The plant yield depended on soil contamination and mineral amendments. In the series without neutralizing materials, the level of 600 mg Cu kg−1 reduced the yield and increased leaf greenness. Lime alleviated the toxicity of Cu in objects with 200 mg Cu kg−1. Zeolite slightly mitigated the harmful effects of Cu at the level of 400 and 600 mg kg−1. Zeolite lowered the SPAD index. In the chemical composition of plants, the content of Cu, K, Mg, Na and Ca in plants increased to 400 mg Cu kg−1, while the content of P decreased to 600 mg Cu kg−1. Among the materials, lime reduced the Cu accumulation in plants the most, followed by clay. Cu narrowed the majority of ratios and widened the Ca:P and K:Ca ratios in plants. The applied mineral materials, except lime, did not significantly affect the formation of these indicators.

“…Long before "biobased" became a catchphrase, CB oil-derived products were used for centuries (e.g., in ancient Egypt lamps) [21,109]. Currently, CB oil has more than 700 industrial uses, and its global demand is increasing steadily by 3-5% per year [54]. It is a well-recognized commodity with a well-established market, costing 2-3 times more than soybean oil being cultivated only in a few countries [21].…”

“…Castor bean plants exhibit a well-documented copper phytostabilization aptitude. Copper-contaminated soil seems to increase the biomass production of CB plants [35,55], without significant phytotoxic symptoms except for chlorosis in a few leaves, indicating its Cu-tolerant capacity [35,54]. Copper concentration in roots greatly exceeds the concentration in other tissue [53,175].…”

Biofuel Production with Castor Bean: A Win–Win Strategy for Marginal Land

et al. 2020

The urgency to reduce resource depletion and waste production is expected to lead to an economy based on renewable resources. Biofuels, for instance, are a great green alternative to fossil fuel, but they are currently derived from edible vegetable oils such as soybean, palm, and sunflower. Concerns have been raised about the social–economic implication and ecological impacts of biodiesel production. Cultivating new lands as biodiesel feedstock rather than food supply, with the consequent increase in food prices, leads to so-called indirect land-use change (ILUC). Establishing bioenergy crops with phytoremediation ability on contaminated soils offers multiple benefits such as improving soil properties and ecosystem services, decreasing soil erosion, and diminishing the dispersion of potentially toxic elements (PTEs) into the environment. Castor bean is an unpalatable, high-biomass plant, and it has been widely demonstrated to possess phytoremediation capability for several PTEs. Castor bean can grow on marginal lands not suitable for food crops, has multiple uses as a raw material, and is already used in biodiesel production. These characteristics make it perfect for sustainable biodiesel production. Linking biofuel production with environmental remediation can be considered a win–win strategy.

“…The results showed that the translocation and accumulation of Cu was higher in the roots of R. communis under NH 4 + application compared with that under NO 3 application. Also, NH 4 + application increased R. communis tolerance to Cu stress, evident by the presence of black granules suggested to be protein and starch grains, which are involved in the detoxification of Cu in tissues (Zhou et al 2020). These studies indicate that application of mineral fertilizers may enhance R. communis growth, metal uptake, and tolerance Pagination not final (cite DOI) / Pagination provisoire (citer le DOI) in metal-contaminated soil; however, the mode of application and type and amount of minerals applied should be taken into consideration.…”

Soil contamination with toxic metals is a major global concern due to their effects on plants and the ecosystem. In contaminated soils, some plant species have the ability to remediate heavy metals. Ricinus communis L., is an industrial crop plant gaining popularity in the remediation of heavy metal-contaminated soils owing to its strong and deep penetrating roots aiding high metal accumulation and large biomass level. R. communis can tolerate high amount of metals by adopting different strategies which include the production of antioxidant enzymes, subcellular localization, and exudation of organic acid. At the molecular level, R. communis can tolerate metal stress by activating stress-responsive genes. Proper selection of metal tolerant R. communis cultivars is effective in the remediation of metal-contaminated soils, owing to their high capacity for metal tolerance. Exogenous application of mineral fertilization and the use of microbes and chelating agents increase metal solubility and availability for plant uptake in soil. Also, good agronomic practices such as co-planting of R. communis with other leguminous crops, enhance R. communis growth and metal tolerance, thereby improving remediation of metal-contaminated soils. This review, therefore, critically discusses the recent approaches in using R. communis to remediate metal-contaminated soils.
