“…strain C2A showed the capability to tolerate and degrade great amounts of tannic acid, degrading 60–40% of tannic acid within 24 h. Two Klebsiella sp. strains showed similar degradation behaviour for tannic acid and also tolerated quite high amounts of this compound (Ajay Kumar et al ., ; Jadhav et al ., ). In this study, the capability of Klebsiella sp.…”

“…Klebsiella pneumoniae MTCC 7162 was isolated from tannery effluent in the presence of 1% of tannic acid (Sivashanmugam & Jayaraman, 2011), and a Klebsiella sp. strain able to degrade tannic acid was isolated from garden soil (Jadhav et al, 2011). Tannase activity was detected at high levels in all the isolated Klebsiella spp.…”

“…However, several bacteria, yeasts and fungi which are able to degrade or tolerate tannins have been isolated (Mingshu et al, 2006). Different tannic aciddegrading strains belonging to genera Bacillus, Staphylococcus, Klebsiella, Lactobacillus, Streptococcus, Pseudomonas, Pantoea and Serratia are currently known (Deschamps et al, 1983;Ajay Kumar et al, 1999;Pepi et al, 2010;Jadhav et al, 2011;Sivashanmugam & Jayaraman, 2011).…”

Four bacterial strains capable of growing in the presence of tannic acid as sole carbon and energy source were isolated from olive mill waste mixtures. 16S rRNA gene sequencing assigned them to the genus Klebsiella. The most efficient strain, Klebsiella sp. strain C2A, was able to degrade 3.5 g L(-1) tannic acid within 35 h with synthesizing gallic acid as main product. The capability of Klebsiella sp. strain C2A to produce tannase was evidenced at high concentrations of tannic acid up to 50 g L(-1) . The bacteria adapted to the toxicity of tannic acids by an increase in the membrane lipid fatty acids degree of saturation, especially in the presence of concentrations higher than 20 g L(-1) . The highly tolerant and adaptable bacterial strain characterized in this study could be used in bioremediation processes of wastes rich in polyphenols such as those derived from olive mills, winery or tanneries.

“…Hydrolysable tannins (HT) cause necrosis of the liver, hemorrhagic gastroenteritis, jaundice, kidney damage with proximal tubular necrosis, photosensitization and death in severe cases (Dollahite et al 1962 ; Murugan 2010 ). Condensed tannins are flavonoid monomers (Filippich et al 1991 ; Bhat et al 1998 ; Jadhav et al 2011 ). The poisonous effects of Condensed tannins are less well known; in general CT reduces the digestive capacity.…”

Optimization of chromium and tannic acid bioremediation by Aspergillus niveus using Plackett–Burman design and response surface methodology

A chromium and tannic acid resistance fungal strain was isolated from tannery effluent, and identified as Aspergillus niveus MCC 1318 based on its rDNA gene sequence. The MIC (minimum inhibitory concentration) of the isolate against chromium and tannic acid was found to be 200 ppm and 5% respectively. Optimization of physiochemical parameters for biosorption of chromium and tannic acid degradation was carried out by Plackett–Burman design followed by response surface methodology (RSM). The maximum chromium removal and tannic acid degradation was found to be 92 and 68% respectively by A. niveus. Chromium removal and tannic acid degradation was increased up to 11 and 6% respectively after optimization. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) was used to investigate biosorption phenomena.Electronic supplementary materialThe online version of this article (10.1186/s13568-017-0504-0) contains supplementary material, which is available to authorized users.

“…All these reports suggest tannase enzyme activity from anaerobic microbes. Tannase activity was reported in Klebsiella species from different sources (Deschamps et al, 1983;Jadhav et al, 2011;Sivashanmugam and Jayaraman, 2011;Pepi et al, 2013) but not from the rumen microbial culture. Information is scarce on molecular characterization of tannase of the gut microbial origin.…”

Tannase, so called Tannin Acyl Hydrolase (TAH) (E.C.3.1.1.20) is one of the versatile biocatalyst with several industrial applications. It is solely responsible for the degradation of hydrolysable tannin thus surpassing the untoward effects of high concentration of tannin consumption in the gut of small ruminants. In the locality of Palampur the migratory goats and sheep have the unique property to resist excess amount of tannin consumed by them. This is because of their ruminal microflora. The concept of ruminal microflora can be used as Direct Fed Microbial (DFM) gaining momentum now-a-days. Thus in the present study attempts were made to explore new source of tannase producing microbes from the rumen of goats and sheep. Rumen samples were collected over several places of Palampur, then processed and finally the most tannin tolerable cultures were selected. Their genomic DNA were isolated and subjected for 16S rRNA sequencing to characterize the isolates. From the molecular characterization we identified Klebsiella sp. as a novel source of tannase from the rumen of these migratory animals. This is the first report of a Klebsiella sp. from the rumen of migratory small ruminants capable of degrading forage tannin.
