“…Since CMC can be degraded by other enzymes in addition to EG, talking about CMCase activity is correct. In this sense, we can say that A. niger LBM 134 has positive CMCase activity which coincides with the literature (Castrillo et al 2012;Martínez et al 2005;Panda et al 2012;Singhania et al 2017;Maia and Fraga 2017). Respect on BGL and CBH activities, the fluorescence was intense after a few days of incubation; data agreed with the literature that describes species of A. niger as BGLs and CBHs producer and the technique of fluorescence plate contributed more significant results in the study of the potential cellulolytic of A. niger LBM 134.…”

“…Aspergillus is a diverse group of filamentous and cosmopolitan fungi that grow in almost every natural and artificial substrate. These fungi have a significant impact in modern society and are very studied due to their importance in medical and industrial mycology (Samson et al 2014;Park et al 2017). Raper and Fennell (1965) recognised 150 species and currently, more than 340 species of Aspergillus are recognised in 4 subgenera and 19 sections (Houbraken et al 2014;Samson et al 2014;Park et al 2017).…”

“…Species within Aspergillus section Nigri have been used in different industrial bioprocess with enzymatic production being one of the most popular applications of these fungi (Bennett 2010;Park et al 2017). Cellulose degrading enzymes that attack cellulose have been intensely studied due to their wide industrial application (Martínez et al 2005;Kuhad et al 2011;Sohail et al 2016;Park et al 2017). The main cellulases are endo-β-1,4-glucanases (EG, EC 3.2.1.4), cellobiohydrolases (CBH, EC 3.2.1.91) and βglucosidases (BGL, EC 3.2.1.21) (Singhania et al 2017).…”

Aspergillus: is a genus of filamentous and cosmopolitan fungi that includes important species for medical mycology, food, basic research and agro-industry areas. Aspergillus section Nigri are efficient producers of hydrolytic enzymes such as cellulases that are employed in the cellulose conversion. Hence, the search of new cellulolytic isolates and their correct identification is important for carrying out safe biotechnological processes. This study aimed to characterise the cellulolytic potential of Aspergillus sp. LBM 134, isolated from the Paranaense rainforest (Argentina) and to identify the isolate through a polyphasic approach. The fungus was identified as Aspergillus niger and its cellulolytic potential was evaluated by using Congo red technique and fluorescence plate assays for carboxymethyl cellulase, β-glucosidase and cellobiohydrolase, respectively. All three cellulase activities were positive; this bio-prospective positioned A. niger LBM 134 as a promising alternative for industries that require organisms capable of carrying out cellulosic biomass processing.

“…Enzymes of industrial interest are routinely being explored in various microbial hosts to increase the yield, to satisfy the needs of both the manufacturer and the end user. Microbes serve as a producer a variety of enzymes that have been successfully used on industrial scale, [1], [2]. Microbial enzymes have found their applications in textile (Amylase, Cellulose and Oxedoreductase); detergents (Protease, Lipase and Cellulase); paper (Xylanase and Lipase); food (Pectinase, Protease and Cellulase) and leather (Protease and Lipase) industries.…”

The brown rot fungus Rhizopus delemar F2 was shown to produce extracellular thermostable and multiple carbohydrase enzymes. The potential of Rhizopus delemar F2 in utilizing apple pomace under solid state fermentation (SSF) is the purpose of the study. Solid state fermentation (SSF) is a very effective technique opposed to submerged fermentation in various aspects. Enhanced production of multiple carbohydrases 18.20 U g−1 of cellulose, 158.30 U g−1 of xylanase, 61.50 U g−1 of pectinase and amylase 21.03 U g−1 was released by microwave pretreatment of apple pomace at 450 W for 1 min and then by incubation the culture thus obtained at 30 °C for 6 days with moisture content of 1:4.5. Apple pomace can serve as a potential source of raw material for the production of multiple carbohydrases. Besides, it can find great commercial significance in production of bioethanol and various industries like textile, fruit juice, paper and pulp industry.

The impact of six local isolates of Penicillium frequentans recovered from healthy sugar beet (Beta vulgaris L.) leaves was evaluated against Cercospora beticola, the causal pathogen of Cercospora sugar beet leaf spot under laboratory and field conditions. In in vitro studies, all the six isolates were able to inhibit the mycelial growth of C. beticola with variation in their antagonistic capability. P. frequentans isolates produce pectinase and cellulase at different degrees. There was a correlation between enzyme activity and the antagonistic ability for each isolate. The high antagonistic ability isolates had the most enzyme activity. In field studies, some adhesives such as agar, starch flour, white glue, gum, and commercial adhesive (Triton Mok) were added to conidia spore suspensions of P. frequentans at 1% to improve conidial adhesion to sugar beet plant surface. Data also showed that all adhesives increased (P = 0.05) the efficiency of the spore suspension of P. frequentans to control the disease. The starch flour at 1% gave a significant reduction in disease severity from 43.23 to 10.42% pre-infection and from 43.23 to 10.52% post-infection. The application of P. frequentans led to improved root yield and the sugar percent of sugar beet crop in two tested seasons.
