Carbohydrate degrading enzyme production by plant pathogenic mycelia and microsclerotia isolates of Macrophomina phaseolina through koji fermentation

Utilization of Orange Peel, Corn Steep Liquor, and Parboiled Rice Water in the Production of Polygalacturonase from Aspergillus niger

“…During the initial period, the filamentous fungus consumes readily available sugars; however, enzyme production occurs in response to nutrient depletion when the microorganism begins to use the complex substrates ( Figs. 2A and B); the same behavior was demonstrated by Kaur et al 34 Similar behavior was observed for potassium, magnesium, and iron (Fig. 2B)-with total consumption of 33%, 46%, and 50%, respectively-indicating a slow and progressive decrease during bioproduction.…”

8 Degradation and Modification of Plant Biomass by Fungi

“…A larger study in which genomes of 18 Dothidiomycetes were compared also revealed significant differences in CAZy numbers in subgroups of these fungi, in particular for CAZy families related to cellulose degradation . The expanded number of cellulose-related genes in another Dothidomycete, Macrophomina phaseolina (Islam et al 2012), correlates well with its previously reported high cellulase activity (Kaur et al 2012). In contrast, Mycosphaerella graminicola has a strongly reduced genome content related to plant cell wall degradation, which is supported by its poor growth on cell wall polysaccharides, such as xylan .…”

Perspective of apple processing wastes as low-cost substrates for bioproduction of high value products: A review

“…The highest xylanase production observed was 35987 65 IU/g (48 h) and 3952 778 IU/ g dry substrate (72 h) in Erlenmeyer flasks and plastic trays under optimal conditions using initial moisture of 85% (v/w), pH 5.0 and inducers veratryl alcohol (2 mM/kg), lactose 2% (w/w), and copper sulfate (1.5 mM/kg). More recently, the inherent potential of the phytopathogenic fungus, Macrophomina phaseolina, was evaluated for the production of various hydrolytic enzymes, such as cellulase, hemicellulase and amylase using AP supplemented with 1% (w/w) rice husk [103]. Among the two different isolates, microsclerotial (MphP) and mycelial (MphM), MphP was observed as a potential source of different hydrolytic enzymes as compared to MphM.…”

“…The ability of the plant pathogenic fungus, M. phaseolina, was evaluated for amylase production using AP through SSF in Erlenmeyer flasks by Kaur et al [103]. Higher amylase activity of 3309.45 7 29.22 IU/gds was recorded with optimum conditions having a temperature of 35 1C using MphP at 70% (v/w) initial moisture level after 120 h incubation time.…”

“…The presence of lignin and cellulose/hemicellulose acts as natural inducers, and most of these residues are rich in sugar, promoting better fungal growth and thus making the process more economical especially for the cellulo-and ligninolytic enzymes [33,132,38]. AP has been used for the production of organic acids [153,39,40,48], aroma compounds [18,168,120], bioethanol [128,129,135], enzymes [63,41,42,43,47,103,175], edible mushrooms [182,54,, edible fibers [72,114,135], pectin recovery [149], natural antioxidants [65,6], protein enriched animal feed [13,36,7,150,171], and insect diets [71] among others. AP has also been considered for environmental applications, such as textile dye removal [142] and as heavy metal absorbent [126].…”
