“…Another strain, P. ceylanicum , also was found to degrade Acid Red 97 and FF Sky Blue dyes by up to 80% after 26 days 10 . Silva-Stenico et al 25 observed greater than 50% degradation of the indigo dye and six other structurally different dyes by the Phormidium sp. and two another cyanobacterium strains, Synechococcus sp.…”

Dyes are recalcitrant compounds that resist conventional biological treatments. The degradation of three textile dyes (Indigo, RBBR and Sulphur Black), and the dye-containing liquid effluent and solid waste from the Municipal Treatment Station, Americana, São Paulo, Brazil, by the cyanobacteria Anabaena flos-aquae UTCC64, Phormidium autumnale UTEX1580 and Synechococcus sp. PCC7942 was evaluated. The dye degradation efficiency of the cyanobacteria was compared with anaerobic and anaerobic–aerobic systems in terms of discolouration and toxicity evaluations. The discoloration was evaluated by absorption spectroscopy. Toxicity was measured using the organisms Hydra attenuata, the alga Selenastrum capricornutum and lettuce seeds. The three cyanobacteria showed the potential to remediate textile effluent by removing the colour and reducing the toxicity. However, the growth of cyanobacteria on sludge was slow and discoloration was not efficient. The cyanobacteria P. autumnale UTEX1580 was the only strain that completely degraded the indigo dye. An evaluation of the mutagenicity potential was performed by use of the micronucleus assay using Allium sp. No mutagenicity was observed after the treatment. Two metabolites were produced during the degradation, anthranilic acid and isatin, but toxicity did not increase after the treatment. The cyanobacteria showed the ability to degrade the dyes present in a textile effluent; therefore, they can be used in a tertiary treatment of effluents with recalcitrant compounds.

“…[ 4,5 ] The industrial application of cyanobacteria can not only reuse the cyanobacteria bloom to bring considerable economic benefits, but also provide a solution to the salvaged cyanobacteria distribution problem, avoiding its secondary pollution. It has been found that cyanobacteria have broad application prospects in many industries, such as pharmacy, [ 6 ] biopolymers, [ 7 ] textiles, [ 8 ] and wastewater treatment. [ 9 ] However, until now, some technical problems have remained unsolved between the theoretical study of cyanobacteria and large batch industrial production.…”

Carbon quantum dots (CQDs) are becoming powerful fluorophore materials in the field of biosensors and bioimaging thanks to their small size, optical properties, biocompatibility, and low toxicity. Heteroatom doping can endow CQDs with new or improved photoluminescent properties. In this paper, the bio‐waste cyanobacteria, H3PO4 and C2H8N2 were used as precursors for synthesizing P‐doped, N‐doped and P/N co‐doped CQDs via a simple hydrothermal method. Under the irradiation of ultraviolet light (UV), the optimal emission peaks of undoped CQDs and P‐doped CQDs were located in the blue‐light region, while those of N‐doped CQDs and P/N co‐doped CQDs were located in the green‐light region. Compared with the undoped, N‐doped and P‐doped CQDs, the P/N co‐doped CQDs had higher quantum yield (QY) and more favourable photoluminescent (PL) properties. The as‐prepared P/N co‐doped CQDs were highly fluorescent and exhibited excitation wavelength‐dependent fluorescence; its maximum emission wavelength was at 501 nm under the excitation of 420 nm. Furthermore, the percentage of survival cells kept at 90.4% when the P/N co‐doped CQDs concentration was up to 200 μg/mL by MTS assay. Such P/N co‐doped CQDs were then used as an effective fluorescent probe for cell imaging due to their high QY, good water dispersibility, strong fluorescence properties, fine biocompatibility, and low cytotoxicity.

O presente trabalho foi realizado com apoio da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior-Brasil (CAPES)-Código de Financiamento 001 ABSTRACT Taxonomy, genomics and functional potential of the cyanobacteria Oxynema sp. CENA135 Oxynema is a derivated genus from the polyphyletic Phormidium and with few registered species, which were found in mangroves, marine or high salinity environments. The taxonomic and genomic informations are almost nonexisting for this genus, with a few exceptions of 16S rRNA and 16S-23S ITS sequences available at databases. Previous studies performed with Oxynema sp. CENA135 isolated from a Brazilian mangrove showed its potential to synthesize siderophores, aliphatic hydrocarbons, anticancer and antibiotic substances, besides its effective degradation of some types of textile dyes. In this work, the strain Oxynema sp. CENA135 was analyzed under a polyphasic approach (morphology, habitat, phylogenomics, phylogeny of the 16S rRNA gene and secondary structure of 16S-23S ITS), including the search for genes or gene clusters related to the biosynthesis of natural products and the detection of associated bacteria. After morphological characterization using an optic and a scanning microscopes, the genomic sequencing was performed from a mate pair library at the HiSeq (Illumina) platform. This is the first genome of the genus Oxynema and, therefore, for its assembly it was used a de novo method resulting in 11 scaffolds in a total size of 6.2 Mbp, with N50 of 3,591,108 pb, GC content of 51.6% and average coverage of 190x. The checkM software estimated a high completeness of the genome (99.29%) and few contaminations (1.22%). Genome mining revealed a biorremediation potential due to the presence of genes related to resistance of copper,...
