“…Among filamentous fungi, the Aspergillus and Penicillium genera are the main tannase producers (Batra and Saxena, 2005;Chhokar et al, 2010;Enemuor and Odibo, 2010;Renovato et al, 2011). Tannase at industrial scale is also produced mainly from Aspergillus species under submerged fermentation (Beniwal et al, 2012).…”

“…A significant effect of incubation period on tannic acid degradation was observed with a maximum response at 96 h, further increase in incubation period caused decrease in tannic acid degradation. This may be due to accumulation of gallic acid, the major end product of tannic acid degradation . Mohan et al found maximum tannase production by A. flavus at 96 h of incubation .…”

Tannery effluent is characterized by high concentrations of chromium, nitrogen, sulfur compounds, and organic matter such as tannins. Chromium and tannins are considered an important source of contamination due to their toxic nature and large volume of liquid discharged and solid sludge produced. In the present study, bioremediation of chromium and tannic acid is studied in a batch culture system using response surface methodology. Scanning electron microscopy (SEM) coupled with energy‐dispersive X‐ray (EDX) and Fourier‐transform infrared spectroscopy (FTIR) are used to investigate adsorption phenomena. A chromium and tannic acid resistance fungal strain is isolated from tannery effluent, and identified as Aspergillus fumigatus MCC 1175 based on its 18S rDNA gene sequence. The minimum inhibitory condition (MIC) of the isolate against chromium and tannic acid was found to be 0.2 and 10 mg mL−1, respectively. The maximum Cr(VI) removal efficiency of 65.1% is found at optimum condition of pH 7, 96 h incubation period, 2.75% inoculum, and 0.1 mg mL−1 chromium. The maximum degradation of tannic acid (63.0%) occurs at pH 5, 27.5 mg mL−1 tannic acid, 100 rpm agitation speed, and an incubation period of 96 h. FTIR analysis of A. fumigatus MCC 1175 revealed the presence of carboxyl and phosphate groups as possible binding sites.

“…The high productivity obtained by SSF is because the similarity between cultivation conditions and those of the natural media of filamentous fungi as well as the low protease activity compared to the SF process [29][30][31]. These advantages have raised the interest of researchers to obtain several biocatalysts of industrial interest, such as lipases [14,[32][33][34][35][36][37][38], proteases [39][40][41], cellulases [42,43], xylanases [44,45], pectinases [16,46], amylases [47][48][49], phytases [50][51][52], inulinases [53,54], tannases [55,56], and others [57] (Table 1). The metabolic expression of fungi differs according to the type of the residues used as substrate, which Catalysts 2017, 7, 9 4 of 34 allows the production of enzymes with different features that can be utilized in the biotechnological industry in different forms [58].…”

Abstract:The establishment of a bioeconomy era requires not only a change of production pattern, but also a deep modernization of the production processes through the implementation of novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting materials in the production of commodities such as biofuels and other high added value chemicals. The utilization of renewable raw resources and residues from the agro-industries, and their exploitation through various uses and applications through technologies, particularly solid-state fermentation (SSF), are the main focus of this review. The advocacy for biocatalysis in green chemistry and the environmental benefits of bioproduction are very clear, although this kind of industrial process is still an exception and not the rule. Potential and industrial products, such as biocatalysts, animal feed, fermentation medium, biofuels (biodiesel, lignocelulose ethanol, CH 4 , and H 2 ), pharmaceuticals and chemicals are dealt with in this paper. The focus is the utilization of renewable resources and the important role of enzymatic process to support a sustainable green chemical industry.
