2025-12-01 – Weekly Marine Biology News : Microalgae's bioreactor potential

Last week, the forum buzzed with discussions around the potential of using marine life in innovative ways. Many members explored how microalgae and marine microbes could transform biopharmaceuticals. There was also a lively exchange on capturing mixture toxicity in natural environments, emphasizing practical field methods. Conversations touched on the implications of nitrogen reduction on eelgrass recovery and the importance of phytoplankton in driving DMS fluctuations. The community showed a keen interest in advancing their skills in ocean-climate data analysis, reflecting a broader trend towards interdisciplinary expertise.

In our 5 L photobioreactor runs, the best yield bump came from a dusk-phase tweak β€” β€˜Nβˆ’ for about 36 h + blue:red β‰ˆ2:1’ β€” which consistently boosted polyketides in Tetraselmis, but it goes south fast without a HEPA on the sparge line; anyone seeing similar with Nannochloropsis, @seaworkbench?

But @k_lee In coastal samples, I consistently got 2–3Γ— higher signal for low‑MW amines using 85 Β΅m Carboxen/PDMS after basifying to ~pH 11 and adding about 20% NaCl, but only once we silanized the vials β€” otherwise the amines stick; if you’re chasing C4+ and up, PDMS/DVB ran cleaner for us.

Quick tip: pairing POCIS (https://pubs.usgs.gov/tm/10/c4/) with a handheld PAM fluorometer on a β€œsentinel” Tetraselmis bag gave us clean reads on mixture toxicity while tracking nitrogen swings β€” like putting a Fitbit on the site. Small caveat: standard POCIS undercalls tiny amines unless you swap in WAX; @steve_harv87, have you tried WAX‑POCIS against your SPME setup?
