Biogenic metallic nanoparticles (BMNPs) are nanostructure materials synthesized through biological processes that have gained significant attention due to their small size and high surface area-to-volume ratio. BMNPs several advantages over chemically ones eco-friendly synthesis regimen, sustainability, biocompatibility, diverse multifarious biomedical applications. Moreover, the superior cytoc...

This report presents a methodological framework for assessing the extent to which the production, processing, and use of biogenic material at stationary sources results in a net atmospheric contribution of biogenic carbon dioxide (CO2) emissions. Biogenic CO2 emissions are defined as CO2 emissions related to the natural carbon cycle, 1 as well as those resulting from the production, The framewo...

Bacterial cell growth necessitates synthesis of peptidoglycan. Assembly of this major constituent of the bacterial cell wall is a multistep process starting in the cytoplasm and ending in the exterior cell surface. The intracellular part of the pathway results in the production of the membrane-anchored cell wall precursor, Lipid II. After synthesis this lipid intermediate is translocated across...

N-Alanyldopamine (NBAD) is the primary catechol tanning agent precursor in typical brown or yellow insect cuticle. The insect integument enzyme responsible for the synthesis of NBAD was reported to be expressed solely in the epidermis, and only at the time of cuticle sclerotization. However, in this study we demonstrate directly that the enzyme also is expressed in a constitutive manner in the ...

Biogenic sources contribute a large portion of emissions of volatile organic compounds (VOCs), a precursor to tropospheric ozone (O3). These emissions are difficult to control and are affected by land-use and climate. A sensitivity analysis was performed using an emissions scenario with a 100% increase in biogenic emissions and another scenario with an additional 100% increase in motor vehicle ...

One plant seed extract (Psidium guajava) was screened for their bioreduction behavior for synthesis of silver nanoparticles. Psidium guajava (PG) was found to exhibit the good reducing and protecting action in terms of synthesis rate and monodispersity of the prepared silver nanoparticles. UV–visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmis...

The spread of contagious diseases and the increase in the drug resistance amongst pathogens has enforced the researchers to synthesize biologically active nanoparticles. Development of eco-friendly practice for the synthesis of nanoparticles is growing bit by bit in the field of nano-biotechnology. The present investigation outlines the development of a method to biosynthesize copper nanopartic...

In many areas, natural sources contribute a substantial fraction of volatile organic compound (VOC) emissions, which are precursors to tropospheric ozone (O3). To investigate the significance of biogenic VOC emissions on ozone formation, meteorological and air quality modelling were used to generate hourly ozone estimates for a case-study high ozone episode in the Mid-Atlantic region of the Uni...

The purpose of this study was to elucidate the characteristics and mechanisms of adsorption and desorption for heavy metals by micro and nano-sized biogenic CaCO3 induced by Bacillus subtilis, and the pH effect on adsorption was investigated. The results showed that the adsorption characteristics of Cd2+ and Pb2+ are well described by the Langmuir adsorption isothermal equation, and the maximum...
