Background:Cyanobacteria, including pharmaceutically and medicinally valuable compounds attract the great attention lately. Norharmane (9H-pyrido (3,4-b) indole found in some cyanobacteria revealed a great number of biological effects.Objective:Seven cyanobacteria were isolated and identified from Yesilirmak River and Gaziosmanpasa University Campus to determine the norharmane content.Materials and Methods:Cyanobacteria collected from Tokat, Turkey were isolated and identified by morphologically. Norharmane (9H-pyrido [3,4-b] indole) quantities were presented for seven cyanobacteria, Chroococcus minutus (Kütz.) Nägeli, Geitlerinema carotinosum (Geitler) Anagnostidis, Nostoc linckia Bornet ex Bornet and Flahault, Anabaena oryzae F. E. Fritsch, Oscillatoria limnetica Lemmermann, Phormidium sp. Kützing ex Gomont, and Cylindrospermum sp. Kutzing ex E. Bornet and C. Flahault by high-performance liquid chromatography.Results:The norharmane amount indicated for cyanobacterial culture media altered in a species-dependent kind in the range of 0.81–10.87 μg/g. C. minutus produced the most norharmane among the investigated cyanobacteria as 10.87 μg/g.Conclusion:Cyanobacteria could be an important source of norharmane as well as pharmaceutically valuable compounds.SUMMARY Seven cyanobacteria were isolated and identified from Yesilirmak RiverQuantitative analysis of norharmane was executed on isolated cyanobacteriaFour cyanobecteria species included the norharmaneChroococcus minutus contained the most norharmane (10.87 μg/g).

Background Cyanobacteria are ecologically significant prokaryotes that can be found in heavy metals contaminated environments. As their photosynthetic machinery imposes high demands for metals, homeostasis of these micronutrients has been extensively considered in cyanobacteria. Recently, most studies have been focused on different habitats using microalgae leads to a remarkable reduction of an array of organic and inorganic nutrients, but what takes place in the extracellular environment when cells are exposed to external supplementation with heavy metals remains largely unknown. Methods Here, extracellular polymeric substances (EPS) production in strains Nostoc sp. N27P72 and Nostoc sp. FB71 was isolated from different habitats and thenthe results were compared and reported. Result Cultures of both strains, supplemented separately with either glucose, sucrose, lactose, or maltose showed that production of EPS and cell dry weight were boosted by maltose supplementation. The production of EPS (9.1 ± 0.05 μg/ml) and increase in cell dry weight (1.01 ± 0.06 g/l) were comparatively high in Nostoc sp. N27P72 which was isolated from lime stones.The cultures were evaluated for their ability to remove Cu (II), Cr (III), and Ni (II) in culture media with and without maltose. The crude EPS showed metal adsorption capacity assuming the order Ni (II) > Cu (II) > Cr (III) from the metal-binding experiments.Nickel was preferentially biosorbed with a maximal uptake of 188.8 ± 0.14 mg (g cell dry wt) −1 crude EPS. We found that using maltose as a carbon source can increase the production of EPS, protein, and carbohydrates content and it could be a significant reason for the high ability of metal absorbance. FT-IR spectroscopy revealed that the treatment with Ni can change the functional groups and glycoside linkages in both strains. Results of Gas Chromatography-Mass Spectrometry (GC–MS) were used to determine the biochemical composition of Nostoc sp. N27P72, showed that strong Ni (II) removal capability could be associated with the high silicon containing heterocyclic compound and aromatic diacid compounds content. Conclusion The results of this studyindicatede that strains Nostoc sp. N27P72 can be a good candidate for the commercial production of EPS and might be utilized in bioremediation field as an alternative to synthetic and abiotic flocculants.

“…Microorganisms exhibit important roles in several biological applications (Ferdes et al, 2020;Mandal et al, 2006;Mehmetoğlu et al, 2020). Green chemistry demonstrates biological pathways and resources that can be used in the bioproduction of NPs and is highly demanded in the bioproduction of NPs via a stable eco-friendly process without using toxic chemicals and extensive manufacturing processes (Li et al, 2007;Mehmetoğlu et al, 2020;Ramya et al, 2020;Zinicovscaia et al, 2016). Boroumand et al (2019) indicated that SeNPs have several important functional uses, such as antimicrobial, antioxidant, and anti-inflammatory properties, and it protects against the adverse side effects of chemotherapeutic drugs.…”

Eco‐friendly selenium nanoparticles (SeNPs) were prepared by biological‐methods using three individual or mixed strains of lactobacilli, which were evaluated for yield, selenium content, and particle size. The prepared SeNPs were used to fortify yoghurt, and the product was evaluated for its chemical composition, rheological properties, and microbiological quality. The highest SeNPs yield was obtained using Lactobacillus casei (26.87 g/L), whereas L. acidophilus produced nanoparticles with a significantly high selenium content. The lowest particle size (131.0 nm) was found in eco‐friendly SeNPs produced using mixed strains followed by those produced using L. plantarum (146.2 nm), L. acidophilus (202.8 nm), and L. casei (271.3 nm). Adding eco‐friendly SeNPs had no notable effect on the chemical composition and texture of functional yoghurt. Eco‐friendly SeNPs powder prepared with L. plantarum had the highest viable count, whereas the lowest was obtained using the mixed culture. No cytotoxicity was observed in a tested colon cancer cell line for all prepared eco‐friendly SeNPs. Practical applications The methods used in the preparation of selenium nanoparticles using lactic acid bacteria are safe, cheap, and easy to apply. It can be applied on an industrial scale as one of the ingredients that can be used to safely support different foods. Selenium nanoparticle prepared in this way can be added in the fortification of milk, children's food, and also bakery products to meet their daily needs of the important selenium element. They can also be produced in tablets containing the daily dose of selenium and also supported by probiotic bacteria. Therefore, the method used to prepare selenium nanoparticle in this study is one of the most promising ways to be applied in different food products.
