This work reports a novel solution-based method to trigger the growth of diatoms for enhanced biomass production, which can efficiently stimulate their applications in nutraceuticals, aquaculture and wastewater remediation. The optimization for the growth of three marine diatoms species was performed using inductively coupled plasma (ICP) synthesized nanosilica which can be a cost-effective and productive method for biomass production. The exponential growth phase was achieved in 14 days with high biomass productivity compared to F/2-Si Media [Chaetoceros sp. (125 ± 3 & 750 ± 3 mgLday); Skeletonema sp., (185.3 ± 2.63 & 562.5 ± 3.96 mgLday) and Thalassiosira sp. (312.5 ± 2.51 & 433.5 ± 1.80 mgLday)] along with a sharp rise of 50-100 fold increment in pigmentation. This work opens up an avenue with novel insights to trigger the growth of diatoms on large scale leading to their better exploitation towards biotechnological applications.

Anthropic activities such as industries, agriculture and mining has generated public concern for its numerous irregular disposals of its waste, the incorrect deposition of heavy metals such as nickel (Ni) has caused the degradation and contamination of groundwater and water. Studies that point out cheap and efficient solutions have been an obstacle to the advancement of solutions for degraded area recovery programs. For this, a vegetable home experiment was developed, with an entirely randomized design with 5 treatments being a control (no metal) and 4 nickel concentrations (200 μM/L; 400 μM/L; 600 μM/L and 800 μM/L) with 6 repetitions.

Sustainable management of textile industrial wastewater is one of the severe challenges in the current regime. It has been reported that each year huge amount of textile industry discharge especially the dye released into the environment without pre-treatment that adversely affect the human health and plant productivity. In the present study, different bacterial isolates had been isolated from the industrial effluents and investigated for their bioremediation potential against the malachite green (MG) dye, a major pollutant of textile industries.

Second-generation (2G) bioethanol production, derived from lignocellulosic biomass, has emerged as a sustainable alternative to fossil fuels by addressing growing energy demands and environmental concerns. Fungal sugar transporters (STs) play a critical role in this process, enabling the uptake of monosaccharides such as glucose and xylose, which are released during the enzymatic hydrolysis of biomass. This mini-review explores recent advances in the structural and functional characterization of STs in filamentous fungi and yeasts, highlighting their roles in processes such as cellulase induction, carbon catabolite repression, and sugar signaling pathways.

With climate change, the frequency of regions experiencing water scarcity is increasing annually, posing a significant challenge to crop yield. Barley, a staple crop consumed and cultivated globally, is particularly susceptible to the detrimental effects of drought stress, leading to reduced yield production. Water scarcity adversely affects multiple aspects of barley growth, including seed germination, biomass production, shoot and root characteristics, water and osmotic status, photosynthesis, and induces oxidative stress, resulting in considerable losses in grain yield and its components.
