Mean values of 96-h LC50 and lethal concentrations were calculated for MM treatment with 95% confidence interval by using the Probit analyses method (Hamilton et al., 1977) with the help of MINITAB while the data on accumulation and catalase
assay were analyzed by using Statistix 8.1 computer software.
The increase of peroxidase and catalase
activity in overcoming dormancy treatments with heated water at 75 and 95[degrees]C is indicative that these enzymes acted to keep low levels of the [H.sub.2][O.sub.2] radical in the apoplast of the tegument cells, enabling in this way the loosening of their walls and facilitating the water inflow and germination.
, its polymorphisms, regulation and changes of its activity in different diseases.
(2013) A simple assay for measuring catalase
activity: A visual approach.
Antioxidant enzymes superoxide dismutase, glutathione peroxidase, catalase
, and antioxidant substances are among the antioxidative materials of the antioxidative system of the body that has an inherent place within this system (5).
An enzymatic defense system include catalase
and ascorbate peroxidase (Desikan et al., 2004).
The 16S rRNA gene of the strain shares high sequence identity with isolates from the termite hindgut (Figure 2), and also, some characteristic features, such as catalase
, have been identified in M.
from bovine liver (CAT, EC 188.8.131.52, activity [greater than or equal to] 10,000 U [mg.sup.-1] protein) was supplied by Sigma-Aldrich (Switzerland) and stored at -20[degrees]C.
It was unexpected since in our previous investigations [K.sub.2][[B.sub.3][O.sub.3][F.sub.4]OH] showed noncompetitive inhibition of enzymes catalase
and different carbonic anhydrases [11, 12].
plays a critical role in ROS metabolism.
Jia and his colleagues have produced the recombinant catalase

2001) and catalase
enzyme was estimated by methods of .
