“Deployment of Green Technologies to Improve Environment and Economy”

Hon’ble Minister for Road Transport and Highways/Micro, Small & Medium Enterprises (MSME) Shri Nitin Gadkari called for the deployment of green technologies to improve the environment and economy. He was speaking at the 63rd Foundation Day of the CSIR-National Environmental Engineering Research Institute (CSIR-NEERI) on 8 April 2021.  Dr Shekhar C. Mande, Director General, Council of Scientific & Industrial Research (CSIR), Dr Jitendra J. Jadhav, … Continue reading “Deployment of Green Technologies to Improve Environment and Economy”

Antifreeze protein from Ammopiptanthus nanus

In this research resercher discuss about the Temperature stress restricts in plant growth and development. Antifreeze protein (AFP) can improve plants antifreeze ability. In our previous study, the AnAFP gene cloned from Ammopiptanthus nanus was confirmed to be an excellent candidate enhancing plant cold resistance. But, AnAFP protein shared similar structures with KnS type dehydrins including K, N and S domains except ice crystal binding … Continue reading Antifreeze protein from Ammopiptanthus nanus

The molecular pH-response mechanism

Plants need to protect themselves from excess light, which causes photo-oxidative damage and lowers the efficiency of photosynthesis. Photosystem II subunit S (PsbS) is a pH sensor protein that plays a crucial role in plant photoprotection by detecting thylakoid lumen acidification in excess light conditions via two lumen-faced glutamates. However, how PsbS is activated under low-pH conditions is unknown. To reveal the molecular response of … Continue reading The molecular pH-response mechanism

A decadal perspective on north water microbial eukaryotes

The North Water region, between Greenland and Ellesmere Island, with high populations of marine birds and mammals, is an Arctic icon. Due to climate related changes, seasonal patterns in water column primary production are changing but the implications for the planktonic microbial eukaryote communities that support the ecosystem are unknown. Here we report microbial community phenology in samples collected over 12 years (2005–2018) from July to … Continue reading A decadal perspective on north water microbial eukaryotes

Organic matter mineralization in modern and ancient ferruginous sediments

Deposition of ferruginous sediment was widespread during the Archaean and Proterozoic Eons, playing an important role in global biogeochemical cycling. Knowledge of organic matter mineralization in such sediment, however, remains mostly conceptual, as modern ferruginous analogs are largely unstudied. Here we show that in sediment of ferruginous Lake Towuti, Indonesia, methanogenesis dominates organic matter mineralization despite highly abundant reactive ferric iron phases like goethite that … Continue reading Organic matter mineralization in modern and ancient ferruginous sediments

Co-variation of silicate, carbonate and sulfide weathering drives CO2

Global climate is thought to be modulated by the supply of minerals to Earth’s surface. Whereas silicate weathering removes carbon dioxide (CO2) from the atmosphere, weathering of accessory carbonate and sulfide minerals is a geologically relevant source of CO2. Although these weathering pathways commonly operate side by side, we lack quantitative constraints on their co-variation across erosion rate gradients. Here we use stream-water chemistry across … Continue reading Co-variation of silicate, carbonate and sulfide weathering drives CO2

Combining P and Zn fertilization to enhance yield and grain quality in maize grown on Mediterranean soils

The main aim of this study was to elucidate the effect of individual and joint fertilization with P and Zn on maize plants grown on typical Mediterranean soils with a limited Zn availability. For this purpose, we examined the effects of P and Zn fertilization individually and in combination on growth, yield and grain protein content in maize grown in pots filled with three different … Continue reading Combining P and Zn fertilization to enhance yield and grain quality in maize grown on Mediterranean soils

Analysis of biomolecules in cochineal dyed archaeological textiles by surface-enhanced Raman spectroscopy

SERS spectroscopy is successfully employed in this work to reveal different components integrating the cochineal colorant employed for dying archaeological textile samples from the Arica Region in North Chile. This analysis was done by in-situ experiments that does not imply the material (colorant and biomolecules) extraction. The spectroscopic analysis of the archaeological textiles by SERS reveals the presence of bands attributed to carminic acid and … Continue reading Analysis of biomolecules in cochineal dyed archaeological textiles by surface-enhanced Raman spectroscopy

Nanotech-engineering of plants on advance CRISPR–Cas genetic

CRISPR–Cas genetic engineering of plants holds tremendous potential for providing food security, battling biotic and abiotic crop stresses caused by climate change, and for environmental remediation and sustainability. Since the discovery of CRISPR–Cas technology, its usefulness has been demonstrated widely, including for genome editing in plants. Despite the revolutionary nature of genome-editing tools and the notable progress that these tools have enabled in plant genetic … Continue reading Nanotech-engineering of plants on advance CRISPR–Cas genetic

Simultaneous bioremediation of cationic copper ions and anionic methyl orange azo dye by brown marine alga Fucus vesiculosus

Textile wastewater contains large quantities of azo dyes mixed with various contaminants especially heavy metal ions. The discharge of effluents containing methyl orange (MO) dye and Cu2+ ions into water is harmful because they have severe toxic effects to humans and the aquatic ecosystem. The dried algal biomass was used as a sustainable, cost-effective and eco-friendly for the treatment of the textile wastewater. Box–Behnken design … Continue reading Simultaneous bioremediation of cationic copper ions and anionic methyl orange azo dye by brown marine alga Fucus vesiculosus
