Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Polyhydroxyalkanoates(PHAs): sustainable biopolyester production

Polimery, 2002
Microbial polyhydroxyalkanoate (PHA) reserve polymers are interesting polyesters that can be sustainably produced by biotechnological means from a variety of renewable substrates. By feeding cosubstrates to selected cultures of prokaryotic microorganisms composition, structure and therefore physical properties of the PHAs can be influenced during their

Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, EarlyView.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Can Polyhydroxyalkanoates Be Produced Efficiently From Waste Plant and Animal Oils?

Frontiers in Bioengineering and Biotechnology, 2020
Polyhydroxyalkanoates (PHAs) are a potential replacement for some petrochemical-based plastics. PHAs are polyesters synthesized and stored by various bacteria and archaea in their cytoplasm as water-insoluble inclusions.

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and
