“…To date, only three bacterial laccases have been completely purified and characterized (as opposed to more than 100 fungal laccases): (1) from the rhizospheric bacterium A. lipoferum (Givaudan et al, 1993); (2) from a melanogenic marine bacterium M. mediterranea (Solano et al, 1997); and (3) from the endospore coat component CotA of B. subtilis (Kim et al, 2006). Laccases from Streptomyces lavendulae (Nandan and Nampoothiri, 2014) and S. cyaneus (Teeradakorn et al, 1998) have also been reported. Bacterial laccases normally have a higher pH optimum than fungal laccases (Margot et al, 2013), with optimum pH being acidic for the latter (Table 1) (Dhakar and Pandey, 2013).…”

Lignin has a significant and largely unrealized potential as a source for the sustainable production of fuels and bulk high-value chemicals. It can replace fossil-based oil as a renewable feedstock that would bring about socioeconomic and environmental benefits in our transition to a biobased economy. The efficient utilization of lignin however requires its depolymerization to low-molecular weight phenolics and aromatics that can then serve as the building blocks for chemical syntheses of high-value products. The ability of laccase to attack and degrade lignin in conjunction with laccase mediators is currently viewed as one of the potential "breakthrough" applications for lignin valorization. Here, we review the recent progress in lignin biodegradation with laccase-mediator systems, and research needs that need to be addressed in this field.

Selection of fusant cultures, producers of bioactive compounds is of significant importance for the biotechnology industry.Protoplast fusion between prototrophic strains of Aspergillus oryzae PP, producer of alfa-amylase and Apergillus awamori K-1, producer of xylanase was obtained. The interspecific nature of the fusants was determined by morphology and screening for combined enzymatic activity. The aim of this investigation was to quantitate the dominant parental genome in the fusants by applying whole genome typing strategy based on the Amplified Fragment Length Polymorphisms (AFLP) technique. In addition we investigated the genome decomposition of the fusant cultures from first to fourth generation. Our results demonstrate that the appearances of the fusants varied but they basically resembled Aspergillus awamori. On the bases of more than 80 polymorphic markers, the genomic analysis confirmed that Aspergillus awamori is the dominant genome (>85%) in the fusants. The stability of the fusants was examined by successive subcultures. The genomic decomposition of the fusants between first and forth generation is as little as 3%. From our studies we could conclude that AFLP is an efficient and discriminatory method for evaluation of the dominant genome in fusant cultures and the extent of genomic decomposition in the generations.
