“…The weights of the leather pieces (1 mm 3 ) were recorded after drying them in a hot air oven, after which they were sterilized by UV radiation (Pandi et al, 2019;Chatterjee et al, 2017). The four isolates were inoculated in nutrient broth media separately along with 1 piece of dried and sterilized leather.…”

West Bengal has several leather industries and as such huge amount of leather are processed every year. The tannery effluents are discharged into the land and open water causing soil and water pollution respectively. Chromium is one of the most toxic inorganic contaminants which is well known for its carcinogenicity. Thus, our study focuses on investigating the bioremediation potential of common microflora isolated from tannery wastewater. In our study, Isolate 1 has the highest ability to reduce chromium (Cr6+) as compared to others. Isolate 4 has the highest protease, lipase and leather degradation activities. Isolate 1 shows the maximum keratinase activity making it an effective strain for keratinase production. Also, it has been found that pH 8 and temperature 40 °C was most suitable for keratinase production. Owing to the multidimensional ability of these two isolates, they were identified by 16S rRNA sequencing and it reveals that Isolate 1 and Isolate 4 belong to Bacillus cereus F4810/72 and Brevibacillus brevis F4810/72 respectively. Thus, this study establishes the role and efficiencies of these microorganisms in combatting pollution, particularly in the water bodies in which harmful chemicals leak regularly owing to improper waste management by various industries.

“…Li et al [17] described that catechol could be degraded by 88.4% within 2 h in the presence of free laccase; Zhang et al [18] found that the removal efficiency of 2,4-dichlorophenol (2,4-DCP), 2-chlorophenol (2-CP), and 4-chlorophenol (4-CP) could reach 94%, 75%, and 69% within 10 h on laccase, respectively. In addition, laccase is considered as an efficient enzyme for dye degradation, and the application of laccase to degrade leather dyes enables cleaner production [19][20][21]. However, the environmentally sensitive, low stability, and unrecyclable nature of free laccase have limited its industrial application to a certain extent [22].…”

Chlorophenols, used as the fungicides in leather, are strictly limited in leather products. In this work, a metal–organic framework material, zeolitic metal azolate framework-7 (MAF-7), was first used to encapsulate laccase (Lac) to prepare MAF-7/Lac bio-composites with 98.5% immobilization yield. Afterward, Lac/MNP@MOM was formed by introducing the magnetic nanoparticles (MNPs) into the Lac@MOM. MAF-7 with better hydrophilicity and stronger pH buffering ability, exhibits good compatibility with laccase, which can reserve the activity of laccase after immobilization. Moreover, the porous structure of MAF-7 is favorable for the sufficient contact between laccase and substrates. Lac/MNP@MOM exhibited excellent activity when exposed to high temperature, extreme pH, and organic solvents, which also simplified complex recovery steps. Furthermore, the degradation rate of 2,4-dichlorophenol (2,4-DCP) could reach as high as 97% within 24 h by immobilized laccase, and after nine consecutive cycles of operation, enzyme activity could remain over 80%, which gives it the potential for practical applications.

“…The dye decolourization potential of laccase have been previously studied especially from Streptomyces ipomoeae CECT 3341 [12], Aspergillus sp. [13] and Peroneutypa scoparia [14]. However, the production of laccase from Aspergillus carbonarius is scarcely reported.…”

Introduction: Laccase is a muilti-copper enzyme that directs oxidation of compounds by reducing oxygen to water molecules. It has been identified as a significant enzyme which possesses diverse interest in industrial sector due to its ability to degrade toxicants from dye-utilizing related industries. Aim: The current research focuses on the optimization of laccase from Aspergillus carbonarius F5 on Delonix regia pods, for application in dye degradation. Methodology: Potential laccase producing fungi were screened and characterized using 18s rRNA. Laccase production was further conducted on untreated and acid pretreated Delonix regia pods. Plackett-Burman design and Central Composite Design (CCD) of the Response Surface Methodology (RSM) was used to screen for various nutritional and environmental factors to improve the yield of the enzyme and then applied for dye decolorization studies. Results: The fungal strain with the highest laccase activity was identified as Aspergillus carbonarius F5. The acid pretreated Delonix regia pods showed considerably high enzyme activity when compared with untreated. Moreover, variation of notable nutritional and environmental factors were detected to improve laccase yield. The effect of input parameters such as incubation period, pH, temperature and MgSO4 were documented as the major factors influencing high laccase yield using Plackett-Burman design. Results obtained from the modelling of experiment using CCD-RSM shows that maximum laccase production of 8.04 U/ml was recorded at temperature 36°C, pH 6, MgSO4.7H2O at 0.2 (g/L), and 7 days which reveals a 8.28 –fold increase. The outcome of the investigation performed on dye decolorization suggests an 87.6 % and 62.6 % degradation on congo red and malachite green dyes respectively. Conclusion: Delonix regia pods could be an added substrate, suitable for optimization of laccase by Aspergillus carbonarius F5 and the enzyme was capable of decolorizing industrial dyes.
