Applied Environmental Biotechnology(AEB) is a multi-disciplinary natural science open-access journal. The purpose of this journal is to understand the latest advances, innovations, and technologies of applied environmental biotechnology, and by doing so, to promote active communication and collaborations among environmental biotechnology scientists around the world.

AEB's Focus and Scope have been updated, subject areas may include, but are not limited to:

    ·Biodegradation Microbiology,

    ·Biotechnological products and process engineering

    ·Bioenergy and biofuels

    ·Ecotoxicology and risk assessment

    ·Environmental engineering and bioremediation

    ·Ecosystem Restoration

    ·Assessment of Risks and Interactions of Pollutants in the Environment

    ·Global change-induced environmental impacts

    ·Impact of Pollutants on Human and Animal Health

    ·Clean water and wastewater treatment research

    ·Air quality research

We invite contributions of original and high-quality interdisciplinary environmental biotechnology research papers of broad impact. All articles submitted to AEB will undergo a rigorous double-blind peer review. Authors who publish in AEB will be able to make their work immediately, permanently, and freely accessible, and retain copyright to their published work. AEB will pay wide attention to the trends in related fields and insist on publishing original research work of the highest quality.

Abstract

Currently green nanotechnology presents a smart solution to produce novel nanostructured materials that are highly safe and environmentally friendly. In this work, zinc oxide nanoparticles (ZnO NPs) were prepared by employing aqueous mint (M. piperita) seeds extract at 60 oC, as a green synthesis method. Mint seeds extract was chosen among the 6 plant seeds that were the subject of this study as it represents the highest polyphenol and flavonoid seeds extract as well as antioxidant activity. High Performance Liquid Chromatography (HPLC) showed that syringic acid (16%), rutin (22%), and apigenin-7-O-glucoside (29%) were the main component of 70% ethanol mint seeds extract.  The obtained ZnO NPs were examined using an ultraviolet-visible spectrophotometer (UV-VIS), X-ray diffraction (XRD) and transmission electron microscope (TEM). The UV spectrum revealed maximum absorption value at 376 nm, related to bio-syntheized ZnO NPs. The XRD study demonstrated the creation of ZnO NPs. The green synthesized ZnO NPs were spherical in shape with average particles size 80±36 nm. Antibacterial activity of aqueous mint seeds extract and synthesized ZnO NPs were investigated on E. coli and S. aureus and antioxidant activity as well.

Abstract

The “Sistema Arrecifal Veracruzano” (SAV) is a vital marine ecosystem; its resources are continually perturbed due to contamination by anthropogenic activities, with multiple contaminants such as plastics. In aquatic ecosystems, plastics are almost immediately coated by inorganic and organic matter, which is then colonized by microbes to form a biofilm on plastic surfaces. This work aimed to isolate and identify plastic-degrading microorganisms isolated mainly from plastic residues of the SAV biosphere reserve. Eight bacteria and three fungi were isolated from a biofilm in plastic residues from islands of SAV. All the bacteria and one fungus showed evidence of degrading PET, over 10% for two bacteria and 17% for the fungus. All fungi belong to the genus Aspergillus, and bacteria belong to the genera Aneurinibacillus, Bordetella, Bacillus, and Lysinibacillus. Aneurinibacillus migulanus and Aspergillus flavus showed the highest values for PET degradation. Carboxylic ester hydrolase (CEH) activity was detected in all crude extracts from fungi and bacteria growing with PET triturates as a carbon source; the maximum CEH in bacteria was 255 U mg-1 and 780 U mg-1 for fungi.
