“…These authors did not achieve any LAC activity when inducers were not used. Rosale et al (2007) reported LAC activities comparable to this work as well. These authors showed an increase in LAC activity for Trametes hirsuta grown on ground orange peelings due to the addition of 1 mM cupric sulfate.…”

Three species of white rot-fungi (Pleurotus ostreatus, Coriolus versicolor, and Lentinula edodes) were grown on 12 solid media based on several lignocellulosic materials (oak sawdust, coconut husks, coffee husks and corn bran) during 49 days. The media had varied carbon/nitrogen ratios and CuSO 4 content. The objective of the work was to evaluate the effect of the media formulation on the production of lignocellulolytic enzymes and degradation of lignocellulosic components by the three fungal species. C. versicolor exhibited the highest ability to degrade the three main polymers of the lignocellulosic waste materials employed and to produce ligninases with titers as high as 107 U/g solid substrate in the case of laccase. In addition, a mathematical model describing the fermentation kinetics of the cell biomass growth, degradation of lignocellulosic components, and lignocellulolytic enzyme production for the fungal species/medium combination exhibiting the best performance under solid-state fermentation conditions was proposed and validated in the case of C. versicolor. The mathematical model could be used to provide valuable information on the process itself as well as to contribute to the development of a future commercial process for lignocellulolytic enzyme production.

“…Rahardjo et al [8] in their review article, came out with a definition that SSF is the growth of microorganisms on moistened solid substrate, in which enough moisture is present to maintain microbial growth and metabolism, but where there is no free-moving water and air is the continuous phase. Rosales et al [9] gave a simple definition of SSF where the growth of microorganisms is on solid or semisolid substrates or support.…”

Solid state fermentation (SSF) refers to the microbial fermentation, which takes place in the absence or near absence of free water, thus being close to the natural environment to which the selected micro organisms, especially fungi, are naturally adapted. SSF has been used in the world for a long time. This technology is commonly known in the East, for traditional manufacture of fermented foods, and in the west, for mould-ripened cheese. It can be defined as a system, in which the growth of selected microorganism(s) occurs on solid materials with low moisture contents and has been identified as a potentially important methodology and technique in biotechnology. Nowadays, SSF is an economically viable, practically acceptable technology for large-scale bioconversion and biodegradation processes. Development of sustainable SSF and bioprocess technology is an emerging, multidisciplinary field with possible application to the production of enzymes, chemicals, bioethanol and pharmaceuticals. SSF offers many advantages over conventional submerged fermentation (SMF) such as, simple and inexpensive substrates, elimination of the need for solubilisation of nutrient from within solid substrates, elimination of the need for rigorous control of many parameters during fermentation, product yields are mostly higher, lower energy requirements, produce less waste water, no foam generation and relatively easy recovery of end products. SSF provides flexibility in terms of the raw materials to be used and their capability to produce various value-added products. Keywords:

“…According to our literature survey, various studies have achieved different results regarding the effect of syringaldazine on laccase production, depending on factors such as inducer concentration, the content of the cultivation medium, and the types of fermentation and organisms used. KoroljovaSkorobogat'ko et al (1998) reported that syringaldazine is a major contributor to laccase production in C. hirsutus, and Rosales et al (2007) stated that 0.11 µmol/L syringaldazine in ground orange peelings culture medium stimulated laccase activity in T. hirsuta, in comparison to control cultures, but 1 mM Cu sulfate + 0.11 µmol/L syringaldazine showed no significant increase in laccase activity. On the other hand, 0.11 µmol/L did not lead to a noticeable increase in laccase activity in C. hirsutus, C. fulvocinerea, or C. maxima (Gorbatova et al, 2006).…”

Introduction Laccases(EC 1.10.3.2, p-diphenol:dioxygen oxidoreductases) are industrially important multicoppercontaining enzymes. Although laccases are produced by some higher plants, insects, bacteria, and fungi, these enzymes are mainly abundant in white rot fungi (Gochev and Krastanov, 2007;Shraddha et al., 2011). These fungi, including Trametes, Pleurotus, Coriolopsis, and other genera, produce laccase enzymes at varying rates (Tapia-Tussell et al., 2011). Trametes is one of the most effective laccase-producing genera (Jang et al., 2002;Rosales et al., 2007). Fungal laccases are generally extracellular and they catalyze the oxidation of a wide range of compounds, such as mono-, di-, and polyphenols, aminophenols, methoxyphenols, aromatic amines, ascorbate, and nonphenolic compounds (Thurston, 1994;Couto et al., 2002;Baldrian, 2006;Patel and Gupte, 2016). The nonnecessity of any extraction process for obtaining these enzymes and their low substrate specificities make laccases suitable for many industrial applications, such as pulp delignification and biobleaching, textile dye decolorization, wastewater treatment, fruit juice processing, and construction of biosensors and biofuel cells (Minussi et al., 2002;Giardina et al., 2010;Durán et al., 2014;Yeşilada et al., 2014). Due to their broad industrial and environmental uses, these enzymes have gained increasing attention. Laccase production can be stimulated by various inductive substances, including metal ions, aromatic or phenolic compounds, alcohol, and detergents (Collins and Dobson, 1997;Birhanli and Yesilada, 2006;Tychanowicz et al., 2006;Bettin et al., 2014). Furthermore, inducer concentration, fermentation types, growth media, and incubation conditions have an important effect on laccase production and they are specific to species and strains (Boran and Yesilada, 2011). Many researchers have investigated the effects of various fermentation processes, cultivation conditions, laccase-producing organisms, and inducers on laccase production (
