Arsenic (As) contamination poses an escalating challenge worldwide. Detoxification through reduction, oxidation, efflux, and thiol complexation is likely to play a key role in its management. Rhizospheric microbes and their combination with different traits of As biotransformation and plant growth promotion are known to play a vital role.

Article Synopsis
  • This study investigates the effects of selenium (Se) and silica (Si) on rice plants under arsenic (As) stress, focusing on As accumulation in grains and potential cancer risks.
  • A total of 58 metabolites were identified; arsenic exposure significantly reduced certain sugars while some antioxidant-related sugars increased, but the addition of Se and Si improved sugar levels compared to As exposure alone.
  • The outcomes suggest that using Se with Si not only enhances the nutritional profile of rice but also drastically reduces arsenic accumulation, potentially lowering cancer risk for consumers.

Biomagnification of arsenic in food chain through wheat consumption poses a serious threat to human health. Therefore, it is necessary to elucidate mechanism of arsenic tolerance and detoxification in wheat. The study aimed to unravel the strategies adopted by arbuscular mycorrhizal fungi to alleviate arsenic toxicity in wheat.

Article Synopsis
  • Chromium (Cr), especially in its hexavalent form (Cr(VI)), is highly toxic and common in tannery waste, requiring effective remediation methods due to its environmental hazards.
  • This study explored the use of the fungus Trichoderma yunnanense combined with sugarcane bagasse biochar (SBC) to reduce Cr(VI) levels, achieving a remarkable 99.65% reduction in just 48 hours at a lower concentration.
  • The findings indicate that this combination not only detoxifies Cr(VI) but also enhances fungal growth and enzyme activity, presenting a promising and sustainable bioremediation strategy for contaminated environments.

A novel Pseudochrobactrum saccharolyticum strain NBRI-CRB 13, isolated from tannery sludge, was studied to grow up to 500 mgL of Cr(VI) and showed Cr(VI) detoxification by reducing > 90% of Cr(VI) at different concentrations 25, 50 and 100 mgL. Kinetic studies showed that first-order models were fitted (R = 0.998) to the time-dependent Cr(VI) reduction with degradation rate constant (k) (1.

Globally, rice is becoming more vulnerable to arsenic (As) pollution, posing a serious threat to public food safety. Previously Debaryomyces hansenii was found to reduce grain As content of rice. To better understand the underlying mechanism, we performed a genome analysis to identify the key genes in D.

Free cyanide is a hazardous pollutant released from steel industries. Environmentally-safe remediation of cyanide-contaminated wastewater is required. In this work, Pseudomonas stutzeri (ASNBRI_B12), Trichoderma longibrachiatum (ASNBRI_F9), Trichoderma saturnisporum (ASNBRI_F10) and Trichoderma citrinoviride (ASNBRI_F14) were isolated from blast-furnace wastewater and activated-sludge by enrichment culture.

The success of a species in future climate change scenarios depends on its morphological, physiological, and demographic adaptive responses to changing climate. The existence of threatened species against climate adversaries is constrained due to their small population size, narrow genetic base, and narrow niche breadth. We examined if ecological niche model (ENM)-based distribution predictions of species align with their morpho-physiological and demographic responses to future climate change scenarios.

Article Synopsis
  • Silicon (Si) enhances plant health by improving physiological and metabolic processes, particularly in relation to stress from heavy metals like arsenic (As).
  • The study focused on Bacillus amyloliquefaciens (NBRISN13) and its ability to reduce arsenite (AsIII) translocation in rice, resulting in a 52-72% decrease in grain As content when combined with feldspar.
  • The research highlights the importance of Si and beneficial microbes in decreasing As uptake, relieving oxidative stress, and improving plant growth and yield, paving the way for future studies on microbial interactions and Si transport in plants.

Immobilized biomass of novel indigenous fungal strains FNBR_3, FNBR_6, FNBR_13, and FNBR_19 were evaluated for arsenic (As) removal from aqueous solution. Alginate beads containing 0.1 g biomass were used in a batch experiment (200 mg l As; pH 6).
