Dereplication of Natural Products with Antimicrobial and Anticancer Activity from Brazilian Cyanobacteria

“…There has been a recent increase in the number of studies on natural products synthesized by Brazilian cyanobacteria, particularly on toxins and protease inhibitors [43,44,[51][52][53]. However, the diversity of these organisms and their natural products will likely expand as these ecosystems are further explored [54][55][56]. Therefore, strains were isolated from different biomes and their biosynthetic potential in culture conditions is discussed here.…”

Monilinema gen. nov., a homocytous genus (Cyanobacteria, Leptolyngbyaceae) from saline–alkaline lakes of Pantanal wetlands, Brazil

“…2014, Genuário et al. 2019). Among them, “Nhecolândia” is characterized by the coexistence of freshwater and shallow saline–alkaline lakes with inorganic ion concentrations exceeding 2.5 g · L −1 (Andreote et al.…”

“…2014, Genuário et al. 2019). From the latter, strains CENA520 and CENA532 were sampled from “Salina Verde,” with pH values ranging from 8.4 to 9.7 and electrical conductivity (EC, expressed in mS · cm −1 ) of 1.9–15, and from “Salina Preta” that had a lower range of pH values of 8.5–8.8 and EC of 1.1–4.7 (Andreote et al.…”

An Actinobacterium Strain From Soil of Cerrado Promotes Phosphorus Solubilization and Plant Growth in Soybean Plants

“…Previous studies have reported high numbers of Actinobacteria in Cerrado soils (Nascimento et al, 2005;Suela Silva et al, 2013; de Sales et al, 2017;Vieira et al, 2018;Vargas Hoyos et al, 2019). These soils are acidic and have a low availability of macronutrients (nitrogen, P, potassium, calcium, magnesium, and sulfur) and micronutrients (boron, copper, molybdenum, and zinc) (Cruz Ruggiero et al, 2002;Oliveira and Marquis, 2002;Genuário et al, 2019). Moreover, these soils usually show high aluminum saturation and P fixation potential (Lopes, 1996;Junio de Jesús Lacerda et al, 2015;Mariussi et al, 2019).…”

“…It is a dry and hot environment, but represents a great source of biodiversity; conversely, it has little global recognition compared with the Amazon basin (Marris, 2005;Fonseca and Venticinque, 2018). Several studies have already investigated this biome as a source of raw materials for drug discovery; potential antifungal, antitumor, and antibiotic agents have been identified from plant and microorganismal origin (Quirino et al, 2009;Calixto Júnior et al, 2016;Souza et al, 2016;de Araujo et al, 2018;Genuário et al, 2019). Owing to the favorable resources of the Cerrado biome, such as the flat topography and appropriate soil depth, amount of rainfall, and light intensity (de Pontes et al, 2017) and despite the low pH, low phosphorus (P) content, and high P fixation capacity (Hinsinger, 2001), the Midwest region of Brazil widely cultivates soybean (Glycine max L. Merrill).…”
