“…Even today, STR are the most widely used cultivation systems with large applicability in industry and in laboratory scale, due to their great operational flexibility, being used in a large variety of bioprocesses such as the degradation of toxic compounds and the production of enzymes, biomass, polysaccharides and other microbial metabolites from different organisms [13,14,16,25,28,32,33,43,[49][50][51][55][56][57][58].…”

“…Laccases-mediated systems are a promising alternative in biotechnological processes of environmental interest, e.g. pulp bleaching, discoloration of textile dyes, oxidation of polycyclic aromatic hydrocarbons, detoxification of endocrine-disrupting chemical effluents and environmental pollutants, and phenol removal [12][13][14][15][16]. In addition, they might be used in industries such as cosmetics, chemicals, pharmaceutics, foods and beverages, as well as for preparing clinical diagnostics, biosensors, clarifying and stabilizing fruit juices, and improving the quality of animal feed [17][18][19][20].…”

“…Stirred-tank reactors (STR) have great operational flexibility; however, this type of reactor requires the application of great power to keep the homogeneity of the system and supply oxygen to the microbial population. Under this condition, the agitation impellers promote a relevant difference between the velocities of liquid and solid phases, the last one represented by the fungal biomass, that could cause shear stress and partial destruction of mycelium [16,28]. Thus, the present study evaluated the effect of oxygen supply on laccases production and growth of P. sajor-caju PS-2001 in submerged culture in a laboratory-scale stirred-tank bioreactor.…”

(1) Background: Oxygen supply is an important parameter to be considered in submerged cultures. This study evaluated the influence of different conditions for dissolved oxygen (DO) concentration on laccases activities and growth of Pleurotus sajor-caju PS-2001 in submerged process in stirred-tank bioreactor. (2) Methods: Initially, three different conditions were tested: uncontrolled DO and minimum levels of 30% and 80% of saturation, with the pH controlled between 4.5 and 7.0. (3) Results: Best results were observed at 30% DO (26 U mL-1 of laccases at 96 h), whereas higher mycelial biomass was observed at 30% and 80% DO (above 4.5 g L-1). Four different conditions of DO (uncontrolled, 10%, 30% and 50% of saturation) were tested at pH 6.5, with higher laccases activity (80 U mL-1 at 66 h) and lower mycelial growth (1.36 g L-1 at 90 h) being achieved with DO of 30%. In this test, the highest values for volumetric productivity and specific yield factor were determined. Under the different pH conditions tested, the production of laccases is favoured at DO concentration of 30% of saturation, while superior DO levels favours fungal growth. (4) Conclusion: The results indicate that dissolved oxygen concentration is a critical factor for the culture of P. sajor-caju PS-2001 and has important effects not only on laccases production but also on fungal growth.

“…The genetic analysis utilized ITS 1, and ITS 4 primers have previously been used for identification of white-rot fungi, including Pleurotus albidus (KF280332.1) with 99% identity, M. palmivorus (JQ653424.1) with 98% identity, Trametes hirsuta (KC414249.1) with 99% identity and Pycnoporus sanguineus (AF363759.1) with 99% identity [18]. White-rot fungi are named due to the ligninolytic activity to degrade wood.…”

“…This result indicates that the white-rot fungi used in this study were able to digest the substrate, utilize the materials for the growth, and degrade lignin and release cellulose to improve digestibility. A previous study by [18] reported the high potential of M. palmivorus for delignification as it produces a high ligninolytic enzyme complex, including laccases, lignin, and manganese peroxidase [18,24]. Another research reported that the delignification process by the laccaserich secretome of M. palmivorus decreases the lignin content from 23% to 17%, allowing higher sugars yields after enzymatic hydrolysis eucalyptus wastes [25].…”

The agricultural sector of Indonesia comprises large oil palm and sugarcane plantations. Nearly 50% of the material resulted in organic waste with high lignin and cellulose content during palm oil and sugarcane production. The lignocellulolytic activity of white-rot fungi has been reported to improve the digestibility and nutrient content of plantation waste into feedstock. This study treated lignocellulose waste, including palm kernel meal, oil palm empty fruit bunch, oil palm frond, sugarcane tops, and sugarcane pressmud with white-rot fungi solid-state fermentation system in a petri dish with two replicates. The growth of the fungus in each waste was observed. The Nutrient content, including water, ash, lipid, protein, crude fiber; and the digestibility, including crude and organic fiber digestion of fermented and unfermented waste, were measured. The molecular identification of white-rot fungi in this study was revealed to be Marasmiellus palmivorus. The result indicated that fermentation of M. palmivorus increased the protein level of sugarcane pressmud, palm kernel meal, oil palm frond, and empty fruit bunch. Fermentation also improved digestibility up to 12%. It is concluded that M. palmivorus has a high potential to enhance the digestibility and nutritive value of lignocellulose waste in oil palm and sugarcane plantations.
