Abstract: In this study, laccase production was enhanced using mutant Shiraia sp. The Shiraia sp. GZS1 strain was mutated using ultraviolet irradiation, followed by screening of strains that were resistant to certain stressors. The mutant GZ11K2 was selected and used for further studies. 2,2′-Azino-bis(3-ethylben-zothiazoline-6-sulfonate) was used as substrate for both wild and mutant laccases at optimal pH (4.0). The mutant laccase exhibited a broader active pH range. The mutant laccase also showed a higher optimal cat… Show more

“…Similarly, laccase production has also been improved through UV radiations based mutagenesis, and UV mutant i.e. GZ11K2 was reported as a preferable laccase producer [21]. Likewise, the chemical mutagens are stronger mutagenic agents and cause permanent changes in DNA sequence.…”

“…Hence, fungal laccases generally fail to work in these extreme environments. Bacterial laccases have many remarkable features in comparison with fungal laccases from an industrial point of view such as action over a broad range of temperature and pH with enormous stability against various inhibitory agents …”

“…Bacterial laccases have many remarkable features in comparison with fungal laccases from an industrial point of view such as action over a broad range of temperature and pH with enormous stability against various inhibitory agents. 7,8 To date, only a few bacterial laccases, especially Bacillus species such as Bacillus safensis DSKK5, 9 B. tequilensis SN4, 10 Bacillus sp. ADR, 11 B. sphaericus 12 and Bacillus (HR03), 13 Bacillus sp.…”

“…These resources can be utilized to create new biomaterials such as fuels, chemicals, animal feeds, soil conditioners, and fertilizers [ 2 ]. However, underutilization or ineffective management of these biomasses results in environmental pollution on the earth surface putting humans at various risks [ 3 ].…”

“…Laccases and peroxidases are known oxidoreductive enzymes which are considered to be most effective in the removal of the lignin component of lignocellulose. These lignocellulolytic enzymes have been reported to possess wide applications in textile, paper and pulp, food, chemical, and biobleaching industries and also in biofuel industry for energy generation [ 3 , 10 , 11 ].…”
