I’m a geomicrobiologist with a geologically short attention span. AquaticGeomicro.comhttps://bsky.app/profile/microbesheik.bsky.socialhttps://bsky.app/profile/microbesheik.bsky.social/post/3mjprundrhs2s.@ace-gtdb.bsky.social is there any curation for the GTDB rRNA database? We found cases where a MAG incorporated into GTDB may have several 16S gene copies that have wildly different taxonomy but are all attributed to the MAGs GTDB taxonomy.

Interesting story developing, we didn’t find any Aphanizomenon nitrogenase genes despite being the primary bloom former! Instead, Dolichospermum takes charge of fixing nitrogen during the bloom. https://www.sciencedirect.com/science/article/pii/S1568988325001805?dgcid=author20 Sep 2025 12:13 +0000at://did:plc:yncnuvccga4ccsugwituvpwo/app.bsky.feed.post/3lzbe2zhm4s2zhttps://bsky.app/profile/microbesheik.bsky.social/post/3lsegucuhws2uNice to be out on the water taking samples!

Metaspades assemblies are awful compared to megahit but even the megahit assemblies aren’t great.11 Mar 2025 16:27 +0000at://did:plc:yncnuvccga4ccsugwituvpwo/app.bsky.feed.post/3lk4id7bypc2mhttps://bsky.app/profile/microbesheik.bsky.social/post/3liztqwe42227MAG binning question: do you ignore smaller orphan bins that are likely parts of larger bins, or do you incorporate? If so what are you using?25 Feb 2025 21:49 +0000at://did:plc:yncnuvccga4ccsugwituvpwo/app.bsky.feed.post/3liztqwe42227https://bsky.app/profile/microbesheik.bsky.social/post/3ldmp3gpik227This paper was over 10 years in the making!! I remember the many zoom and in person discussions! Congrats to all the people that have been a part of this work over the years, especially Rick and Mitch, and a HUGE thanks to @emilruff.bsky.social for his tenacity and bringing this to fruition!!
