“…The yeast Rhodotorula sp. Y11 (Li and Yuan, 2008), Phytophthora nicotianae hyphae (Blackman et al, 2005), Rhizopogon roseolus (Miszalski et al, 1998) contained only MnSOD isozymes. Colletotrichum graminicola have three SOD types (Fang et al, 2002).…”

“…Studies of SODs from microbes, animals and plants have been reported (Bridges and Salin, 1981;Bannister et al, 1987;Michalski, 1996;Zbigniew and Wojciech, 2006;Chakrabarty et al, 2007;Li and Yuan, 2008;Seckin et al, 2009), but to our knowledge, little information is available about this enzyme in edible mushrooms. Hence, the objective of this study is to evaluate the SODs of 17 edible mushroom species, including their activity, thermostability and characterisation of SOD isozymes.…”

BackgroundCalcineurin (CaN) is a Ca2+- and calmodulin (CaM)-dependent serine/threonine phosphatase. Previous studies have found that CaN is involved in the regulation of the stress responses.ResultsIn this study, the growth of Cryptococcus humicola was inhibited by the CaN inhibitor tacrolimus (FK506) under aluminum (Al) stress. The expression of CNA encoding a catalytic subunit A (CNA) and its interaction with CaM were upregulated when the concentration of Al was increased. A CaM-binding domain and key amino acids responsible for interaction with CaM were identified. ∆CNAb with a deletion from S454 to A639 was detected to bind to CaM, while ∆CNAa with a deletion from R436 to A639 showed no binding to CaM. The binding affinities of CNA1 and CNA2, in which I439 or I443 were replaced by Ala, were decreased relative to wild-type CNA. The phosphatase activities of ∆CNAa, CNA1 and CNA2 were lower than the wild-type protein. These results suggest that the region between R436 and S454 is essential for the interaction with CaM and I439, I443 are key amino acids in this region. The ability of the CNA transgenic yeast to develop resistance to Al was significantly higher than that of control yeast. Residual Al in the CNA transgenic yeast culture media was significantly lower than the amount of Al originally added to the media or the residual Al remaining in the control yeast culture media. These findings suggest that CNA confers Al tolerance, and the mechanism of Al tolerance may involve absorption of active Al.ConclusionsAl stress up-regulated the expression of CNA. CaM-binding domain and key amino acids responsible for interaction with CaM were identified and both are required for phosphatase activities. CNA conferred yeast Al resistance indicating that the gene has a potential to improve Al-tolerance through gene engineering.

“…In previous studies, the heavy metal tolerance and the removal potential for Cd 2+ , Zn 2+ and Ni 2+ have been focused on planktonic cells of Rhodotorula species, exclusively (SALINAS et al, 2000, REZZA et al, 2001, LI and YUAN, 2008, SUAZO-MADRID et al, 2011, SAN and DÖNMEZ, 2012.

The impact of heavy metals, cadmium (Cd 2+), zinc (Zn 2+) and nickel (Ni 2+) on planktonic cells and biofilm of Rhodotorula mucilaginosa and Saccharomyces boulardii was examined. The metal tolerance testing was performed by MBEC TM-HTP assay. The minimum inhibitory concentration (MICp) and minimum lethal concentration (MLCp) were determined as well as the minimum biofilm eradication concentration (MBEC). Biofilm was more tolerant on the presence of heavy metals than the planktonic cells. The planktonic cells of R. mucilaginosa were tolerant to high concentrations of Cd 2+ , Zn 2+ and Ni 2+ , while the planktonic cells of S. boulardii tolerated Zn 2+ , exclusively. The R. mucilaginosa biofilm was tolerant to all of the tested metal concentrations and the obtained results were confirmed by fluorescence microscopy. S. boulardii did not show ability of biofilm formation. Metal removal efficiency of the R. mucilaginosa planktonic cells and biofilm were also tested. The R. mucilaginosa biofilm showed higher efficiency in metals removing compared to the planktonic cells. Until now, the heavy metal tolerance and the removal efficiency (Cd 2+ , Zn 2+ and Ni 2+) analyzes were performed solely on planktonic cells of Rhodotorula species. In this study, we investigated the metal removal efficiency of R. mucilaginosa planktonic cells and biofilm and compared the obtained results.
