Hierarchical porous biochar from kelp: Insight into self-template effect and highly efficient removal of methylene blue from water
Bioresour Technol. 2023 Jan 24;372:128676. doi: 10.1016/j.biortech.2023.128676. Online ahead of print.ABSTRACTBiochar is known to efficiently remove dyes especially for biochar with hierarchical pores and partial N-species. Here, a facile pyrolysis is used to yield N-doped biochar from kelp without additives, showing surface areas of 771 m2/g as temperature up to 1000 °C and hierarchical small-sized mesopores (2-4 nm) and wide meso-macropores (8-60 nm). A possible self-template mechanism from inorganics is proposed to form hierarchical pore architecture in biochar and used for methylene blue (MB) removal. Biochar pyrolyze...

Analysis of Inclusivity of Published Science Communication Curricula for Scientists and STEM Students
CBE Life Sci Educ. 2023 Mar;22(1):ar8. doi: 10.1187/cbe.22-03-0040.ABSTRACTThere has been an increased push for science, technology, engineering, and mathematics (STEM) students and scientists to be trained in science communication. Science communication researchers have outlined various models of how scientists interact with nonscientists-including deficit, dialogue, and inclusive approaches. We wanted to analyze whether published science communication curricula for STEM students and scientists exhibit features of inclusive science communication. We analyzed n = 81 published science communication trainings. We found an in...

The Saccharina latissima microbiome: Effects of region, season, and physiology
DiscussionWe have shown that the difference in bacterial composition is driven by factors of decreasing importance: (i) the algal tissues (apex/meristem), (ii) the geographical area, (iii) the seasons (at the Roscoff site), and (iv) the algal host’s condition (healthy vs. symptoms). Overall, Alphaproteobacteria, Gammaproteobacteria, and Bacteroidia dominated the general bacterial communities. Almost all individuals hosted bacteria of the genus Granulosicoccus, accounting for 12% of the total sequences, and eight additional core genera were identified. Our results also highlight a microbial signature characteristic for al...

Antiviral and antibacterial properties of phloroglucinols: a review on naturally occurring and (semi)synthetic derivatives with potential therapeutic interest
Crit Rev Biotechnol. 2023 Jan 2:1-18. doi: 10.1080/07388551.2022.2160695. Online ahead of print.ABSTRACTPhloroglucinol and derived compounds comprise a huge class of secondary metabolites widely distributed in plants and brown algae. A vast array of biological activities, including antioxidant, anti-inflammatory, antimicrobial, and anticancer has been associated to this class of compounds. In this review, the available data on the antiviral and antibacterial capacity of phloroglucinols have been analyzed. Some of these compounds and derivatives show important antimicrobial properties in vitro. Phloroglucinols have been sho...

Removal of heavy metals from aqueous solutions by high performance capacitive deionization process using biochar derived from Sargassum Hemiphyllum
In this study, biochar derived from brown algae Sargassum hemiphyllum prepared by pyrolysis at 300 - 700°C and then used as the CDI electrode to remove Cu(II) from aqueous solutions. According to the findings, the optimal pyrolysis temperature was 700°C, and the electrosorption capacity of BAB700 was 75 - 120 mg·g-1 at an applied voltage of 1.2 V across wide range of initial pH, temperatures and ion types. Moreover, BAB700 also exhibited outstanding ability to electrosorb other heavy metals (Zn(II), Ni(II), and Cd(II)). In addition, the BAB700 retained the Cu(II) removal efficiency of 70% in 10 cycles. Cu(II) in actual ...

Methyldecanoate isolated from marine algae Turbinaria ornata enhances immunomodulation in LPS-induced inflammatory reactions in RAW 264.7 macrophages via iNOS/NF κB pathway
This study identifies the anti-inflammatory, antioxidant, and immunomodulatory potential of a fatty acid methyl ester segregated from the brown algae Turbinaria ornata and identified by nuclear magnetic resonance and mass spectrometry as methyl 6,12-dimethyltridecanoate (ET). Antioxidant and anti-inflammatory effects of ET were studied on lipopolysaccharide (LPS)-induced inflammatory reaction in RAW 264.7 macrophages. Moreover, in silico docking studies of is olated ET with inflammatory markers TNFα, NFκB, and COX-2 showed potent binding scores suggesting anti-inflammatory potential. ET significantly reduced LPO an...
