Enhancement of isoprene production in engineered Synechococcus elongatus UTEX 2973 by metabolic pathway inhibition and machine learning-based optimization strategy.

An engineered Synechococcus elongatus UTEX 2973-IspS.IDI is used to enhance isoprene production through geranyl diphosphate synthase (CrtE) inhibition and process parameters (light intensity, NaHCO and growth temperature) optimization approach. A cumulative isoprene production of 1.

Kinetic modeling for miniaturize single-chambered microbial fuel cell: effects of biochemical reaction on its performance.

In this study, Nernst growth model equations are used to explain the anodic biofilm (ABF) modeling, linear sweep voltammetry (LSV) at various growth stages of biofilm, and polarization curve modeling for its electron generation behavior in a miniaturized single-chambered microbial fuel cell (SMFC). Kinetic constants of various growth model equations were determined using non-linear regression analysis. Maximum specific growth rate (μ) at anodic surface is observed 0.

A hybrid ultrafiltration membrane process using a low-cost laterite based adsorbent for efficient arsenic removal.

Adsorption has proven to be most effective for arsenic removal. But standalone adsorption cannot cater to the need for large-scale treatment in centralized water supply systems. Combining adsorption with other low-pressure membrane processes may aid in scaling up and intensifying the overall arsenic removal.

Emerging trends in the pretreatment of microalgal biomass and recovery of value-added products: A review.

Microalgae are a promising source of raw material (i.e., proteins, carbohydrates, lipids, pigments, and micronutrients) for various value-added products and act as a carbon sink for atmospheric CO.

A mini review on microwave and contemporary based biohydrogen production technologies: a comparison.

Hydrogen gas, along with conventional fossil fuels, has been used as a green fuel with enormous potential. Due to the rapid depletion of fossil fuels, a new dimension of hydrogen production technology has arrived to reduce reliance on nonrenewable energy sources. Microwave-based hydrogen production is a more promising and cost-effective technology than other existing green hydrogen production methods such as fermentation and gasification.

Critical review on processing technologies and economic aspect of bio-coal briquette production.

The world is looking for alternative energy resources because of the depletion of fossil fuel reservoirs like crude oil, coal, and natural gases in the next few decades. In this aspect, unutilized coal waste and sustainable biomass are considered major energy contributors to convert biomass blended coal fines as high-quality solid briquettes. The present study integrates different briquette processing technologies to develop, coal-biomass-binder, coal-biomass (binderless), coal-binder, and carbonized biomass-binder composites.

Chitosan-Fe-Al-Mn metal oxyhydroxides composite as highly efficient fluoride scavenger for aqueous medium.

Nano-particles are highly efficient fluoride adsorbents, but agglomerate easily due to their high surface activity and are difficult to separate from aqueous medium after use. Mixed-metals oxyhydroxides nano-particles were prepared into a natural polymeric matrix of chitosan to overcome these problems. Hydrous mixed-metal oxyhydroxides, loaded chitosan composite (Fe-Al-Mn@chitosan) was prepared using abundantly available laterite clay and waste from steel industry via co-precipitation method.

Polygenic study of endurance-associated genetic markers ACE I/D, ACTN3 Arg(R)577Ter(X), CKMM A/G NcoI and eNOS Glu(G)298Asp(T) in male Gorkha soldiers.

Background: Gorkhas, a sub-mountainous population of the Himalayan region, are known for strength and bravery. In the present study when "Gorkha" is used without brackets, we are mentioning Gorkhas of Tibeto-Burman origin. Physical capability, strength and endurance are important components of fitness associated with genetic traits.

Genetic Diversity in Gorkhas: an Autosomal STR Study.

Genotyping of highly polymorphic autosomal short tandem repeat (STR) markers is a potent tool for elucidating genetic diversity. In the present study, fifteen autosomal STR markers were analyzed in unrelated healthy male Gorkha individuals (n = 98) serving in the Indian Army by using AmpFlSTR Identifiler Plus PCR Amplification Kit. In total, 138 alleles were observed with corresponding allele frequencies ranging from 0.

Diversified genomic contribution among south Indian populations--a study on four endogamous groups of Andhra Pradesh.

Background: The present study examines genomic variation among three tribal (Nayakpod, Thoti and Kolam) and a caste (Niyogi Brahmin) population groups of Andhra Pradesh, south India.

Aim: The present study examined the genomic diversity of the populations in relation to other population groups of India using 20 autosomal loci.

Subjects And Methods: A total of 204 blood samples from the population groups described above were collected and analysis was carried out following standard protocols.
