Gender representation on environmental sciences editorial boards.

Gender representation in science has been extensively investigated by scientists from different disciplines and locations. Men continue to publish, collaborate, and obtain more citations than women. We investigated the relationship between Editor-in-Chief (EiC) and Editorial Boards' (EB) gender representation and the impact factor (IF) of environmental science journals (ESJ).

Trends on Microalgae-Fungi Consortia Research: An Alternative for Biofuel Production?

The utilization of microalgae and fungi on an industrial scale is a challenge for researchers. Based on the question "how fungi have contributed to microalgae research?," we verified the scientific trends on microalgae-fungi consortia focused on biofuels production by searching for articles on the Web of Science and Scopus databases through the terms "microalgae" or phytoplankton and "fung." We found 1,452 articles published between 1950 and 2020; since 2006, the publication numbers have increased rapidly.

Immobilization of α-Amylase onto Luffa operculata Fibers.

A commercial amylase (amy) was immobilized by adsorption onto Luffa operculata fibers (LOFs). The derivative LOF-amy presented capacity to hydrolyze starch continuously and repeatedly for over three weeks, preserving more than 80% of the initial activity. This system hydrolyzed more than 97% of starch during 5 min, at room temperature.

Immobilized horseradish peroxidase on discs of polyvinyl alcohol-glutaraldehyde coated with polyaniline.

Discs of network polyvinyl alcohol-glutaraldehyde (PVAG) were synthesized and coated with polyaniline (PANI) using glutaraldehyde as a chemical arm (PVAG-PANIG-HRP disc). The best conditions for the immobilization were established as about 1.0 mg mL(-1) of protein, for 60 min and pH 5.
