Biotechnological potential of Neolyngbya (Cyanobacteria), a new marine benthic filamentous genus from Brazil

Novel marine cyanobacteria from the Atlantic coast of Brazil

“…Although the Brazilian seashore extends for about 7,400 km and has a continental shelf area of about 3.4 million km 2 , few studies have been conducted investigating the marine cyanobacterial diversity and its potential for natural product biosynthesis (Baeta-Neves & Tribuzi, 1992;Branco, Moura, da Silva, & Bittencourt-Oliveira, 2003;Branco, Sant'Anna, Azevedo, & Sormus, 1996;Branco, Sant'Anna, Paiva Azevedo, & De, Sormus, 1997;Caires et al, 2018aCaires et al, , 2018bCaires, Sant'Anna, & de Castro Nunes, 2013;Crispino & Sant'Anna, 2006;Nogueira & Ferreira-Correia, 2001;Silva, Genuário, Vaz, & Fiore, 2014). In recent years, the isolation of marine cyanobacteria from Brazilian coastal areas, followed by their polyphasic evaluation, has led to the characterization of new strains (Silva et al, 2014) as well as the description of novel genera, for example, Halotia (Genuário, Vieira Vaz, Hentschke, Sant'Anna, & Fiore, 2015), Aliterella (Rigonato et al, 2016), Neolyngbya (Caires et al, 2018b) and Capillus (Caires et al, 2018c).…”

Some of these isolated strains have been already investigated regarding the production of bioactive secondary metabolites of biomedical and biotechnological interest (Caires et al, 2018a;Silva et al, 2014). In addition, recently erected taxa such as Moorea (Engene et al, 2012), Caldora (Engene et al, 2015), Toxifilum (Zimba, Huang, Foley, Linton, & Vis, 2017) and Dapis (Engene, Tronholm, Paul, & De Clerck, 2018) have also been reported to be prolific producers of bioactive compounds.…”

“…Considering that marine tropical cyanobacteria have been characterized as prolific sources of bioactive secondary metabolites (Armstrong, Vaz, Genuário, Fiore, & Debonsi, 2019;Caires et al, 2018a;Engene et al, 2013Engene et al, , 2012Engene et al, , 2015Silva et al, 2014), we hypothesize that the strains isolated from the Brazilian Atlantic coast can be a potential source of natural products. For this purpose, we isolated marine cyanobacterial strains, which were characterized in terms of morphology and molecular phylogeny, as well as subjected to nucleoside and amino acid prospection.…”

The occurrence of Affixifilum gen. nov. and Neolyngbya (Oscillatoriaceae) in South Florida (USA), with the description of A. floridanum sp. nov. and N. biscaynensis sp. nov

“…Species in Neolyngbya are exemplary sources of compounds with antibiotic and antifungal properties (Caires et al. 2018c), while Moorena is known to produce lyngbyatoxin‐a, Lyngbya majuscula and L. aestuarii produce dragonamides, and Lyngbya sp. and Microseira (albeit freshwater) are known to produce cylindrospermopsin (McGregor and Sendall 2015, Engene et al.…”

“…Caires et al. (2018c) noted that various strains of Neolyngbya possessed some of the genes required for microcystin, cylindrospermopsin, and saxitoxin production, as well as N. arenicola having cytotoxic properties. Therefore, an analysis of secondary compounds is warranted to better understand this genus and further work is needed to understand the toxicity of N. arenicola .…”
