Tannase production by Aspergillus spp. UCP1284 using cashew bagasse under solid state fermentation

Abstract

Production of tannase by Aspergillus species UCP1284 was studied using solid state fermentation and cashew bagasse as substrate. Amount of 35 strains of fungi species isolated from soil of Caatinga were used for qualitative selection of strains with potential for production of tannase. Through the selected fungi, a complex study was achieved about the influence of the variables: substrate amount, initial moisture content and tannic acid concentration on the production of tannase by solid state fermentation, using a factorial design (2 3 ). The maximum activity was 12.26 U/g of dry substrate obtained at the time of 48 hours using 10.0 g of substrate with initial moisture content of 40% and using 2.0% of tannic acid. This first design for enzyme production demonstrated the influence of the studied parameters, mainly, substrate amount on the enzyme yield, and its relevance in the process for the subsequent optimization protocol.

Effect of fungal fermentation on apparent digestibility coefficient for dry matter, crude protein and amino acids of various plant protein sources in Penaeus vannamei

“…Emambux and Taylor (2003) suggested that it could partly be attributed to the production of enzyme tannase or microbial phenyl oxidase action. It was reported that A. niger has produced 12.26 U/g of tannase during solidstate fermentation (Liu et al, 2016). Glucosinolates is a major factor restricting the digestibility and utilization of RSM (Shi et al, 2015).…”

Utilization of Glycerol from Biodiesel Industry By-product into Several Higher Value Products

“…The results show that the extract of A. occidentale was best for the induction of tannase production using Aspergillus oryzae in submerged fermentation (Lokeswari 2010). Optimization of process parameters for maximal enzyme productivity in solid state fermentation using cashew apple baggase as substrate was reported by different researchers (Rodrigues et al 2007(Rodrigues et al , 2008Porto et al 2016;Tatiana et al 2016). Viswanath et al investigated the tannase productivity of A. niger CEPC 11 (MTCC 5898) on an abundantly available waste by-product cashew testa under solid state fermentation and response surface methodology was effectively applied for the optimization of factors for the production of tannase.…”

Corn (Zea Mays) Leaves as Cost-Effective Substrate for Enhanced Tannase Production Under Solid State Fermentation: Optimization and Characterization

“…Agricultural wastes such as olive mill waste (Aissam et al 2005), palm kernel cake, tamarind seed powder (Sabu et al 2005), coffee husk (Battestin and Macedo 2007), tea stalks (Xiao et al 2015), rice straw, sugarcane bagasse (Paranthaman et al 2010), cashew bagasse (Liu et al 2016), different fruit seeds (Arshad et al 2019), rice bran, coconut residues (Mansor et al 2019), wheat bran, pomegranate peel, eucalyptus leaves, banana peel, guava (Ahmed and Abou-Taleb 2020) almond and mango leaves (Ire and Nwanguma 2020) have been utilized previously for enhanced tannase synthesis in literature. In contrast, the use of tannic acid in pure form act as an expensive and unaffordable substrate and inducer for tannase synthesis at industrial scale (Mansor et al 2019).…”
