“…Moilanen et al [16] reported that the maximum MnP activity (340 nkat/g DM) occurred after 14 days of fermentation in a solid-state reactor with an internal conveyor, but their MnP activity stayed at almost the same level at 100 g-scale in plastic jars and 4 kg-scale in bioreactor cultivation. A similar study was carried out by Vivekanand et al [32] using a bioreactor that contained four circular aluminum trays, and the maximum MnP activity (1,339.0 ± 131.23 U/l) was obtained after 6 days of SSF by Aspergillus fumigatus VkJ2.4.5. Phanerochaete chrysosporium BKM-F-1767 had also produced 1,293 U/l of MnP activity, in a fixed-bed bioreactor on the 7th day [17].…”

“…However, largescale enzyme production from white-rot fungi is limited mainly owing to the lack of suitable bioreactor configurations for fungal growth and their metabolism [27]. Although several studies on the development of innovative bioreactor systems have already been carried out [7,25,32], an ideal bioreactor for ligninolytic enzyme production from white-rot fungi has not yet been shown [6,8]. Furthermore, the high production cost is another barrier to the commercialization of these enzymes.…”

The growth of Irpex lacteus F17 and manganese peroxidase (MnP) production in a selfdesigned tray bioreactor, operating in solid-state conditions at a laboratory scale, were studied. The bioreactor was divided into three layers by three perforated trays. Agroindustrial residues were used both as the carrier of bound mycelia and as a nutrient medium for the growth of I. lacteus F17. The maximum biomass production in the bioreactor was detected at 60 h of fermentation, which was consistent with the CO2 releasing rate by the fungus. During the stationary phase of fungal growth, the maximum MnP activity was observed, reaching 950 U/l at 84 h. Scanning electron microscopy images clearly showed the growth situation of mycelia on the support matrix. Furthermore, the MnP produced by I. lacteus F17 in the bioreactor was isolated and purified, and the internal peptide sequences were also identified with mass spectrometry. The optimal activity of the enzyme was detected at pH 7 and 25 °C, with a long half-life time of 9 days. In addition, the MnP exhibited significant stability within a broad pH range of 4-7 and at temperature up to 55 °C. Besides this, the MnP showed the ability to decolorize the polymeric model dye Poly R-478 in vitro.

“…Banana peel was the best substrate among the other tested lignocellulosic agro-residues, poplar leaves, wheat bran, rice bran, wheat straw, and bagasse under SSB conditions for obtaining higher laccase production. The laccase activity reached to maximum as 6281.4 U L -1 under optimized conditions of banana peel culture (Vivekanand et al 2011). Our highest laccase activity was 6.97-fold higher than that of it.…”

Lignocellulosic wastes are generally produced in huge amounts worldwide. Peach waste of these obtained from fruit juice industry was utilized as the substrate for laccase production by Pleurotus eryngii under solid state bioprocessing (SSB). Its chemical composition was determined and this bioprocess was carried out under stationary conditions at 28°C. The effects of different compounds; copper, iron, Tween 80, ammonium nitrate and manganese, and their variable concentrations on laccase production were investigated in detail. The optimum production of laccase (43,761.33 ± 3845 U L -1 ) was achieved on the day of 20 by employing peach waste of 5.0 g and 70 lM ammonium nitrate, 750 lM Mn 2? as the inducers. The dye decolorization also researched to determine the degrading capability of laccase produced from peach culture under the above-mentioned conditions. Within this scope of the study, methyl orange, tartrazine, reactive red 2 and reactive black dyes were treated with this enzyme. The highest decolorization was performed with methyl orange as 43 ± 2.8% after 5 min of treatment when compared to other dyes. Up to now, this is the first report on the induction of laccase production by P. eryngii under SSB using peach waste as the substrate.

AbstractBanana peel (BP) is an agrowaste produced in large volumes annually, especially by food-processing industries; however, its disposal is of significant concern. However, recent research suggests that BP is a valuable source of bioactive compounds, which can be converted into value-added products. This article reviews the conversion process of value-added products from BP and provides an outline on the chemical composition of BP and its possible applications. In addition, we also discuss the utilization of BP as a substrate to produce animal feed, biofertilizer, dietary fibers, clean energy, industrial enzymes, as well as its use in the synthesis of nanomaterials. Based on the research conducted so far, it is obvious that BP has a wide variety of applications, and thus, developing a biorefinery approach to adequately utilize BP will help realize its economic benefits to the fullest. Based on the valorization of BP, a scheme for BP biorefinery has been proposed. A material balance for BP biorefinery for 1-ton bone-dry BP is presented and our results show that 432 kg of protein or 170 kg of citric acid, 170 kg of pectin, 325 m
