“…Fungal pretreatment (Table 2) of these effluents under aerobic conditions makes it possible to obtain phenol reduction (51-100%), good decolourisation (31-100%), biochemical oxygen demand (BOD) reduction up to 85.4%, and enzyme production (protease, Lacc (EC 1.10.3.2); LiP (EC 1.11.1.14), MnP (EC 1.11.1.13), amylase, etc.) (Vinciguerra et al, 1995;Yesilada et al, 1995;Garcia et al, 1997Garcia et al, , 2000D'Annibale et al, 1998;Setti et al, 1998;Gharsallah et al, 1999;Robles et al, 2000;Kissi et al, 2001). Amendment of olive mill wastewater (OMW) composition (addition of co-substrate, nutrients, salts) influences the removal of COD, phenols and colours (Yesilada et al, 1998).…”

Fungal biomasses are capable of treating metal-contaminated effluents with efficiencies several orders of magnitude superior to activated carbon (F-400) or the industrial resin Dowex-50. Additionally, fungal biomasses are susceptible to engineering improvements and regeneration of their capabilities. With regard to organic pollutants, excessive nutrients and dyes, fungi can remove them from wastewaters, leading to a decrease in their toxicities. However, the detoxification rates seem to be dependent on media and culture conditions. The postreatement by anaerobic bioprocesses of effluents that have been pretreated with fungi can lead to higher biogas than the original effluents. In addition to the degradation of organic pollutants, fungi produce added-value products such as enzymes (LiP, MnP, Lacc, amylase, etc.) and single-cell protein (SCP). Most research on fungal capacities to purify polluted effluents has been performed on a laboratory scale, hence there is a need to extend such research to pilot scale and to apply it to industrial processes.

Lentinus squarrosulus, an indigenous mushroom specie commonly found growing on dead logs in the Zaria environ of Kaduna State was cultured on six different medium which were inoculated separately with three different spawn grains and amended with six different oils at five different rates. The interaction of spawn grains x culture medium had a highly significant effect on carpophore dry weight and stipe and pileus diameters of L. squarrosulus. The results reveal that the interaction of millet spawn x animal bedding and rice medium induced the widest stipe diameter while the interaction of corn spawn x animal bedding and rice medium induced the heaviest carpophore dry weight as well as the widest pileus diameter.

“…Nevertheless, essential gaps in the study of the biochemical aspects of L. edodes development and cultivation, especially in liquid media, exist to the present day. This paper does not cover traditional techniques for fruiting body production (for these, see e.g., Harris 1986;Kirchhoff and Lelley 1991;Leonard and Volk 1992;Tan and Moore 1992;Worrall and Yang 1992;Levanon et al 1993a, b;Donoghue and Denison 1995;Mizuno 1996;Royse 1995;Vinciguerra et al 1995;Smith 1997;Kalberer 2000;Royse and Sanchez-Vazquez 2001;Philippoussis et al 2003). …”

Extracellular protein production and morphogenesis of Lentinula edodes in submerged culture

Along with a brief review of Lentinula edodes (shiitake mushroom) submerged cultivation history within the framework of important extracellular proteins biosynthesis, this study contains the authors' own results. The possibility of regulating the lectin activity of shiitake using the synthetic components is shown. The time course of lectin production in culture liquid of L. edodes in different media under submerged culture conditions was studied. The activity of agglutinins depended on the ratio between carbon and nitrogen sources and the pH of the culture medium. A relationship between the chemical composition of nutrient medium, the activity of extracellular lectins of L. edodes, and the formation of pigmented mycelial film in liquid culture has been found. The formulation of medium, on which the brown mycelial film appears in several days of submerged cultivation, is proposed. The results obtained make a contribution to the present notion of biochemical processes that give rise to the occurrence of the aforesaid morphological structure of shiitake. Finally, two extracellular lectins from the submerged culture of L. edodes have been isolated and purified to homogeneity. Their physicochemical properties and composition have been studied.
