Laccases is the industrially important enzyme which is widely present in the nature. It play important role in paper and pulp industry, textile industry, synthetic chemistry, cosmetics, soil bioremediation and biodegradation of environmental phenolic pollutant. It is important because it oxidizes both the toxic and nontoxic substrates. Laccases producing bacteria have been isolated and identified by 16s RNA. Laccases genes were identified in Pseudomonas putida and Bacillus licheniformis. Laccase are used in dechlorination process.

Signaling the significant amount of increasing rates of environmental reservoir pollution, heavy metals are considered the most obnoxious of all. Of these we carried out a study on bioremediation trends and patterns of eukaryotic systems and isolated Arsenic-Resistant Yeast species from Lahore Canal Drain and Effluents from Kasur Tanneries, Raiwind and Kala Shah Kaku. The isolates were tested for the arsenic resistance, morphological changes and optimal growth parameters under the arsenic stress. The isolates were also checked for cross-metal resistance checks, evaluated by 18S rRNA...
