Dear colleagues,
I am currently comparing some genomic features in different representatives of Fischerella genus isolated from different eco-types. Unfortunately, neither PCC nor UTEX collection of algae provide the history of PCC 9339/UTEX1829. I just found that UTEX 1829 was deposited by Professor G.L. Tiwari from the University of Allahabad (India) around 1971 but I was unable to find any word about the place of UTEX 1829 isolation. This is why I urge kindly my dear colleagues, especially from the Allahabad University, to share with me any information regarding the history of Fischerella sp. PCC 9339/Fischerella musciola (UTEX1829).
I thank you all in advance.

Dear Igor, here is some information for you: https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/fischerella/pdf
Dear Igor, it seems that Fischerella musciola are terrestrial bacteria: https://chempedia.info/info/fischerella/
Maria S Muntyan Masha, Thanks for the reference but I am hunting for an information about a physic-chemical information about an environment where PCC 9339 was isolated, e.g. T, pH, [different elements] at least. Cheers
There are some information for you in the attached article.
Best regards,
Maria
Dear Igor, the following link might be helpful too: https://www.algaebase.org/search/species/detail/?tc=accept&species_id=30365
Dear Igor, you can find the description of some physical-chemical properties of environments where these organisms thrive in the the attached article:
Dear Masha, Thank you very much for all information. Unfortunately, it did not have any specific word about PCC 9339. Best regards. IB
Dear Igor, the situation with the description and characteristics of all Fischerella strains does not seem very clear and detailed. I can recommend reading the article in Bergey's Mannual (Hoffmann, L., & Castenholz, R. W. (2015). Form‐Fischerella. Bergey's Manual of Systematics of Archaea and Bacteria, 1-6) and, if possible, to find the article by Rippka and Herdmann, 1992, which is cited in the first article.
Continuing the discussion, we must specify that total of 81 Fischerella thermalis strains (also known as Mastigocladus laminosus) were isolated from mat samples in a thermal gradient between 61–46 ◦C (Alcorta et al., 2018, https://doi.org/10.1016/j.syapm.2018.05.006).《Kaštovský and Johansen [21] discussed that M. laminosus and F. thermalis were “almost certainly the same species typified by the same population, with only 39 years of temporal variation in sampling” and that the drawings of F. thermalis (type species for Fischerella)
were subsequently used to characterize soil (mesophilic) strains.》Thus, according to the information above, confusion may be due to two synonyms of the same species.
As a result, many Fischerella strains are also known as Mastigocladus laminosus.
Maria S Muntyan Dear Maria, I just need exact information about physic-chemical parameters of a spot where PCC 9339 was isolated. Nothing more! Thanks. IB
