“…Thereafter, the parameters for obtaining a mixed preparation of enzymes were optimized by OVAT method and subsequently by RSM. Fungi belonging to two different classification groups (Penicillium oxalicum SAU E -3.510 and Pleurotus ostreatus) have been cultured for xylanase and laccase coproduction [13]. But, co-culturing of alkalophilic bacteriaproducing thermo-alkali-stable xylanase and laccase extracellularly has not been reported.…”

“…Vinogradova et al [12] showed that co-cultivation of fungi can enhance the biosynthesis of enzymes. Dwivedi et al [13] developed a mixed enzyme preparation of xylanase and laccase from Penicillium oxalicum SAU E -3.510 and Pleurotus ostreatus. Fungi have been co-cultivated for the production of amino acids [12], enzymes like endoglucanase and b-glucosidase [14], cellulase and xylanase [15].…”

To reduce pollution and cost of treatment for fresh and recycled paper, co-production of xylanase and laccase was carried out in the same production medium using two compatible species of Bacillus. These co-produced enzymes were used for deinking of old newsprint (ONP) and biobleaching of eucalyptus Kraft pulp. Solid-state co-cultivation of Bacillus sp. and B. halodurans FNP135 was optimized statistically by response surface methodology for the co-production of xylanase (X) and laccase (L). A significant increase in production of xylanase (2.1-fold, 1,685 IU/g) and laccase (2.04-fold, 2,270 nkat/g) was observed under optimized conditions viz. pH (10.5), inoculum size (10 + 10 %) and moisture:substrate ratio (0.8:1). Both the enzymes showed identical temperature and pH optima of 70 °C and 9, respectively, and were used for deinking of ONP pulp and biobleaching of kraft pulp. In case of ONP pulp deinking, the XL treatment increased brightness (11.8 %), freeness (17.8 %), breaking length (34.8 %), burst factor (2.77 %) and tear factor (2.4 %). In case of kraft pulp biobleaching, XL treatment showed a significant increase in brightness (13 %), whiteness (106.15 %) breaking length (49 %), burst factor (6.9 %), tear factor (23 %), and viscosity (11.68 %) and reduction in kappa number (15 %) after alkali extraction and peroxide stage. This enhancement of pulp properties revealed a synergistic effect of xylanase and laccase produced in one setup.

“…Therefore, mixed cultivation is expected to have advantages over mono-cultivation for higher substrate utilization, productivity, adaptability for the growth environment and contamination resistance (Dwivedi et al, 2011). Meyer and Stahl (2003) revealed that the impact of co-cultivation were strongly dependent on the medium composition, which affected the co-growth of mixed fungi, leading to enhanced carbon source utilization.…”

Digestibility Fungi Protein enrichmentWinery biomass waste Solid state fermentation a b s t r a c t Grape marc and lees are main waste biomass in wine industry, which contain substantial amount of carbohydrates and nutrients, but currently deliver considerable carbon emission through landfill in Australia. This study was aimed to develop a biotechnological systematic approach to select suitable fungi for bioconversion of the winery biomass wastes into animal feed. The biotech-systematic approach was developed through assessment of nutrient/carbon source accessibility of the fungi, understanding of their metabolic reactions in solid state fermentation, and nutritive value of the fungi-fermented grape marc. From 13Aspergillus, Rhizopus, and Trichoderma fungal species, A. oryzae DAR 3699, A. oryzae RIB40 and T. reesei RUT C30 were determined as the best fungi due to their promising biochemical capabilities to enhance protein contents and in vitro digestibility of grape marc in mono-and co-cultivations. The mono-fungous-cultured SSF process used these selected fungi is able to convert grape marc to nutrient-rich feed by increasing the protein contents from ∼5% to 26% and the digestibility from ∼25% to over 50%. R. oligosporus 2710 with R. oryzae 6201 or T.viride 15719 showed promising protein enrichment to 18-23% and digestibility improvement by ∼50% in their co-cultivations. This preliminary bioengineering strategy will be useful for selecting microorganisms for the bioconversion of organic wastes to high valuable products.This "green cycle" bioprocess will be useful to promote the old-fashioned waste treatment technologies for the cleaner production in food processing industries.

“…These enzymes are not only specific for Mn (II), but also oxidize phenolic and non-phenolic substrates that are typical for LiP, including veratryl alcohol, methoxybenzenes and lignin model compounds in the absence of manganese (Wong 2009). Laccases are blue multicopper oxidases able to oxidize a variety of phenolic compounds, including polyphenols, methoxy-substituted phenols, diamines and a considerable range of other compounds, with concomitant reduction of molecular oxygen to water (Autore et al 2009;Dwivedi et al 2011). They oxidize phenols and phenolic lignin substructures by one-electron abstraction with formation of radicals that can repolymerize, or lead to depolymerization (Higuchi 1989).…”

The valorization of agro-residues by biological routes is a key technology that contributes to the development of sustainable processes and the generation of value-added products. Sugarcane bagasse is an agro-residue generated by the sugar and alcohol industry in Brazil (186 million tons per year), composed essentially of cellulose (32-44%), hemicellulose (27-32%) and lignin (19-24%). The conversion of sugarcane bagasse into fermentable sugars requires essentially two steps: pretreatment and hydrolysis. The aim of the pretreatment is to separate the lignin and break the structure of lignocellulose, and it is one of the most critical steps in the process
