“…Fungal DNA was isolated and sequenced using the ITS DNA sequence as primers, replicated and sequenced using the Sanger's method. The cultures had a BLAST match of 97 % and more of the sequences in the GenBank database were identified as T. versicolor, C. subvermispora, P. radiata, P. affinis, P. cinerea P. setulosa P. chrysocreas, M. fuscoatra, H. radula, B. adusta, , S. gausapatum and P. sordida, 65 . Compared to Sanger sequencing whole genome sequence studies using next generation sequencers revealed high amount of quality information in the recent years, thus slowly we notice increase in the whole genome sequence studies using NGS methods.…”

Lignin is a complex polyphenyl aromatic compound which exists in tight associations with cellulose and hemicellulose to form plant primary and secondary cell wall. Lignocellulose is an abundant renewable biomaterial present on the earth. It has gained much attention in the scientific community in recent years because of its potential applications in bio-based industries. Microbial degradation of lignocellulose polymers was well studied in wood decaying fungi. Based on the plant materials they degrade these fungi were classified as white rot, brown rot and soft rot. However, some groups of bacteria belonging to the actinomycetes, α-proteobacteria and β-proteobacteria were also found to be efficient in degrading lignocellulosic biomass but not well understood unlike the fungi. In this review we focus on recent advancements deployed for finding and understanding the lignocellulose degradation by microorganisms. Conventional molecular methods like sequencing 16s rRNA and Inter Transcribed Spacer (ITS) regions were used for identification and classification of microbes. Recent progression in genomics mainly next generation sequencing technologies made the whole genome sequencing of microbes possible in a great ease. The whole genome sequence studies reveals high quality information about genes and canonical pathways involved in the lignin and other cell wall components degradation.

“…Among fungi with wood decay potential, brown-and white-rot fungi (basidiomycetes) provide greater structural damage to the wood cell wall (Ortiz et al 2013). In the present study, R. confertum and P. chrysosporium belong to this class of fungi, therefore causing greater wood deterioration.…”

This study aimed to identify and evaluate the decay capability of fungi that occur naturally in eucalyptus plantations of three cities in Espírito Santo state, Brazil. Hence, discs from deteriorated stumps were collected and samples isolatied to obtain pure fungal cultures. An experiment using Petri dishes with malt-agar medium and eucalyptus sapwood was performed in order to test the decay of each isolate. The experiment was evaluated by mass loss every four weeks during a total of 20 weeks. Fungi with decay capability were selected and identified via extraction of genomic DNA. Seven isolates were identified: Penicillium implicatum, Resinicium confertum, Phanerochaete chrysosporium, Cladosporium sp., Penicillium sp., Trichoderma citrinoviride and Acremonium sp. Isolation and identification of fungi from eucalyptus stumps provided naturally occurring decay fungi that inhabit the eucalyptus plantations that were adapted for this study.

“…This type of lignin removal is preferable for pretreatment of lignocellulosic substrates since it preserves higher amounts of holocellulose. Ligninolytic abilities of S. gausapatum have not been examined before, although the studies of dead wood from which fungi were collected have shown that S. gausapatum causes simultaneous white rotting ( 54 ). As a primary colonizer of oak branches, S. gausapatum is expected to possess good ligninolytic abilities ( 55 ).…”

SUMMARYThe aim of this research is to isolate and identify fungi with high lignin-degrading abilities that are autochthonous to southern Serbian region. Two novel fungal isolates identified as Trametes hirsuta F13 and Stereum gausapatum F28 were selected to assess their ligninolytic enzyme activities and the efficiency of lignin removal from beech wood sawdust. Obtained results show that both isolates are good sources of industrially valuable enzymes with a potential for application in various biotechnological and industrial processes. Both isolates showed laccase, manganese-dependent peroxidase, and versatile peroxidase activities, while only S. gausapatum F28 had lignin peroxidase activity. This is the first record of the ability of S. gausapatum species to produce lignin peroxidase. T. hirsuta F13 showed higher laccase activity than S. gausapatum F28, while S. gausapatum F28 had higher manganese peroxidase activity. Also, T. hirsuta F13 exhibited much higher laccase activity under submerged cultivation conditions than solid-state cultivation conditions, which is rare for fungi. This is important for industrial processes since the submerged fermentation is a dominant technique in industry. The test of the efficiency of lignin removal showed that both isolates are efficient lignin decomposers. After five weeks of incubation on beech wood sawdust, the total lignin losses were 33.84% with T. hirsuta F13 and 28.8% with S. gausapatum F28.
