Bridging Green Chemistry and Circular Economy: A Pathway to Sustainable Polyester Plastics Through Feedstock, Synthesis, and Waste Upcycling

open access: yesAdvanced Science, EarlyView.
This review summarizes green and low‐carbon strategies throughout the entire life cycle of polyester plastics, including sustainable monomer synthesis, optimization polymerization, efficient recycling, and advanced upcycling technologies. The synergistic implementation of these strategies is expected to significantly promote the development of a ...

Rhodobacter veldkampii, a new species of phototrophic purple nonsulfur bacteria [PDF]

open access: yes, 1985
We describe a new species of purple nonsulfur bacteria, which has the ability to grow under photoautotrophic growth conditions with sulfide as an electron donor and shows the characteristic properties of Rhodobacter species (i.e., ovoid to rod-shaped ...

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

open access: yesAdvanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

Defects in bile pigment metabolism causing jaundice [PDF]

open access: yes, 1961
The excretion of bilirubin and therefore the relief of jaundice is dependent upon at least three factors. First, the bilirubin must be conjugated and thus converted into a water soluble compound: this means its conversion to an ester glucuronide although
