Pomegranate peel is a low-cost substrate for the production of tannase by Bacillus velezensis TA3 under solid state fermentation

Tangerine, banana and pomegranate peels valorisation for sustainable environment: A review

“…Recently, the use of bioresources, such as agri-food wastes for enzyme production has become a major challenge. Thanks to these physicochemical characteristics TPW, PPW and BPW that have been used as substrates for the production of various enzymes, such as the production of α-amylase by Aspergillus flavus AUMC 11685 from TPW [ 30 ], the production of lignocellulolytic enzymes (cellulases, xylanase, laccase, and manganese peroxidase) by Pleurotus dryinus through submerged fermentation of TPW [ 234 ], the production of invertase using Cladosporium cladosporioides [ 235 ] and using the fungal strain Aspergillus flavus [ 236 ] by solid-state fermentation with PPW as substrate, production of tannase from PPW as substrate by Aspergillus niger ITCC [ 237 ] and by Bacillus velezensis TA3 under solid-state fermentation [ 31 ] and also production of amylase from BPW by Aspergillus niger and Bacillus subtilis [ 238 ], and the production of lignocellulose-degrading enzymes (endoglucanase and xylanase) by the submerged fermentation of BPW by Pycnoporus coccineus [ 239 ].…”

“…TPW, PPW and BPW may be used directly or after treatments as animal feed [ 15 , 16 ], soil amendment [ [17] , [18] , [19] ], bio-adsorbents [ 20 , 21 ], and the production of the outputs was obtained by the biorefinery process (biogas, bioethanol and biohydrogen) [ [22] , [23] , [24] , [25] , [26] ]. Numerous other studies have focused on the valorisation of TPW, PPW and BPW for the production of value-added products (essential oil, enzymes, food, medical and cosmetic products) [ [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] ].…”

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

“…Apart from sh, Mondal et al (2001) reported the isolation of tannase producing B. cereus from soil sample. Other tannase producer such as Staphylococcus lugdunensis was isolated from human feces (Noguchi et al 2007), Bacillus velezensis from soil (Lekshmi et al 2020), Serratia marcescens strain IMBL5 from intestinal tract of Onthophagus babirussa IMBL (Thiyonila et al 2020) and Bacillus gottheilii M2S2 from tannery e uent (Subbalaxmi and Murty 2016).…”

“…Under CCD of RSM, optimal tannase production from B. subtilis using corn leaves was achieved with 1.75% tannic acid, 0.75% NaCl and 1.25% malt extract in medium composition. Lekshmi et al (2020) with pomegranate peel as substrate, obtained the highest tannase by B. velezensis TA3 using tannic acid (0.68%) in medium component optimized by CCD under SSF. Selvaraj and Vytla (2018) determined 1% tannic acid as medium component using CCD for optimal tannase synthesis by B. gottheilii M2S2.…”

“…Tannase (tannin acyl hydrolase EC 3.1.1.20) is an enzyme involved in the hydrolysis of the tannic acid and yield of gallic acid and glucose (Kumar et al 2007;Beena et al 2011). This inducible extracellular enzyme is mainly produced by bacteria, yeast and fungi in the presence of tannic acid (Böer et al 2009;Sharma and John 2011;Lekshmi et al 2020). Tannase is considered an industrially important enzyme with several applications specially in pharmaceutical and food industries for gallic acid synthesis, fruit juices clari cation, wine production, coffee-avored drinks and instantaneous tea formation (Lekha and Lonsane 1997;Aguilar et al 2007;Mohapatra et al 2007;Madeira et al 2011;Chávez-González et al 2012).…”
