“…Media optimization for biodecolorization has been widely evaluated for bacteria and filamentous fungi mediated processes. However, most works deal with non-textile dyes (Congo Red or Indigo), initial dye concentrations are usually lower that the ones herein assayed (50-150 mg L -1 ) and cultivation times usually exceed 5 days in multiple works reported [22][23][24][25][26].…”

Trichosporon akiyoshidainum HP2023 is a basidiomycetous yeast isolated from Las Yungas rainforest (Tucumán, Argentina) and selected based on its outstanding textile-dye-decolorizing ability. In this work, the decolorization process was optimized using Reactive Black 5 as dye model. Lactose and urea were chosen as carbon and nitrogen sources through a one-at-time approach. Afterwards, factorial designs were employed for medium optimization, leading to the formulation of a simpler optimized medium which contains in g L: lactose 10, yeast extract 1, urea 0.5, KHPO 1 and MgSO 1. Temperature and agitation conditions were also optimized. The optimized medium and incubation conditions for dye removal were extrapolated to other dyes individually and a mixture of them. Dye removal process happened through both biosorption and biodegradation mechanisms, depending primarily on the dye structure. A positive relation between initial inoculum and dye removal rate and a negative relation between initial dye concentration and final dye removal percentages were found. Under optimized conditions, T. akiyoshidainum HP2023 was able to completely remove a mixture of dyes up to a concentration of 300 mg L, a concentration much higher than those expected in real effluents.

“…Some cyanobacterial species can produce laccases that correlate with biomass formation. Laccase activities of up to 60 U ml −1 are described in the literature for Arthrospira platensis, but other species like for example Nostoc, Synechocystis, and Lyngbya strains show high productivities of laccase activity [36]. Future work should investigate whether the strains used in this work are also capable of producing laccases.…”

Cyanobacteria are promising organisms for the sustainable production of various biotechnologi-cal interesting products. Due to their energy production via photosynthesis, the cultivation of cyanobacteria expands the CO2 cycle. Most cyanobacteria form biofilms on surfaces in their natu-ral environment by surrounding the cells with a self-produced matrix of extracellular polymeric substances (EPS) that hold the cells together. These special growth properties need special reac-tors for cultivation. By immobilizing cyanobacteria on carriers, systems currently established in industry could also be used for biofilm formers. Various artificial carriers for immobilized growth of cyanobacteria and microalgae have already been described in the literature. However, the use of waste materials or natural biodegradable carriers would be more sustainable and is, therefore, the focus of this study. Dried Luffa cylindrica, zeolite, and corn stalks were investigated for their use as carriers for cyanobacteria. L. cylindrica was shown to be an excellent natural carrier for (i) Anabaena cylindrica (ii) Nostoc muscorum 1453-12a, and (III) Nostoc muscorum 1453-12b. Higher or at least similar growth rates were achieved when cyanobacteria were cultivated with L. cylindrica compared to submerged cultivation. Additionally, the production of EPS and C-phycocyanin was increased at least 1.4-fold in all strains by culturing on L. cylindrica. The improved growth could be explained on the one hand by the high surface area of L. cylindrica and its properties, and on the other hand by the release of growth-promoting nutrients from L. cylindrica to the medium.

“…is the microorganism that shows the highest activity on dyes selected. Pseudomonads are reported to grow considerably on plates since 96 h of incubation using different classes and chemical subclasses of textile dyes, including azo, nitro, tri-phenyl methane, and anthraquinone types as the only source of carbon (BMM, dye, and agar) (Afreen et al 2017). Earlier reports strongly revealed that the role of Pseudomonas sp.…”

Background Azo dye effluents cause severe pollution problems in soil and water and affect their flora and fauna throughout the world. The combination of dye degrading bacteria in the gut of freshwater fish has been considered a prospective approach towards the development of a sustainable environment. In the southernmost part of India, especially in the Namakkal District of Tamil Nadu state, urbanization and industrial development lead to various environmental issues. In lieu, most of the earlier works were carried out on the bacterial dye degradation from soil and water sources, least concentration on the dye degradation from fish gut flora. The objective of this study was to analyze the role of dye degrading bacteria in the gut of freshwater fish collected from the study area. Results We have studied the aerobic degradation of remazol yellow reactive dye by bacteria forming the gut flora of exotic fish Oreochromis mossambica from river Cauvery at Pallipalayam of Namakkal District, India. Eight dye degrading gut isolates viz. Pseudomonas sp. AD1, Bacillus sp. AD2, Staphylococcus sp. AD3, Staphylococcus AD4, Enterobacter sp. AD5, Escherichia coli AD6, Streptococcus sp. AD7 and Clostridium sp. AD8 were obtained capable of growing in azo dye incorporated in Basic mineral medium (BMM) medium. Optimization study was carried out for various parameters for the selected isolates. Based on the growth, maximum growth was seen in Pseudomonas sp. AD1 (in 0–24 h) and minimum in Escherichia coli.AD 6 (in 72–96 h). Pseudomonas sp. AD1, Enterobacter sp.AD5, and Bacillus sp. AD 2 exhibited efficient dye degradation during 0–96 h analysis which was confirmed by FTIR analysis. Loss of azo group stretch at 1572–76 cm−1 and 1429 cm−1 and presence of primary (–NH2–) and secondary amides (–NH2–), aliphatic –C–N– stretching and confirmed –C–S– stretching in FTIR analysis confirms the breaking down of the azo bond. Conclusion This study showed that there is a platform for using the bacterial flora of fish gut that paves a prominent way in the degradation of Azo dye.
