Production of lignolytic enzymes by the mushroom fungus Stereum ostrea in liquid medium under conditions of vegetative growth was examined for 10 days in comparison to the reference culture Phanerochaete chrysosporium. Though growth and secretion of extracellular protein by S. ostrea were comparable to those of P. chrysosporium, yields of laccase enzyme by(More)
The white rot fungi Stereum ostrea displayed a wide diversity in their response to supplemented inducers, surfactants, and copper sulphate in solid state fermentation. Among the inducers tested, 0.02% veratryl alcohol increased the ligninolytic enzyme production to a significant extent. The addition of copper sulphate at 300 μM concentration has a positive(More)
Analysis of fifty genotypes of guava for fruit quality attributes such as total soluble solids, lycopene, ascorbic acid and total antioxidant level of fruits revealed the existence of a wide genetic variability for these quality traits. Range of variation for fruit total soluble solids (TSS), lycopene and total antioxidant was 14.19–6.60 %, 0.51–3.03 [mg(More)
INTRODUCTION The application of light and continuous forces for optimum physiological response and the least damage to the tooth supporting structures should be the primary aim of an orthodontist. Nickel-titanium (NiTi) alloys with their desirable properties are one of the natural choices of the clinicians. AIM This study was aimed to compare and rank(More)
INTRODUCTION The cervical vertebral maturation (CVM) method is a vital tool for assessing the biological maturation of the orthodontic patient to evaluate the amount of mandibular bone growth left. AIM To assess and visualize the cervical vertebral morphology (bone density) of orthodontic patients of the age group 9,16,27 years. MATERIAL AND METHODS(More)
Efficiency of white-rot fungi—Stereum ostrea (S. ostrea) as a test culture and Phanerochaete chrysosporium (P. chrysosporium) as a reference culture in colour removal from a textile dye, Remazol brilliant blue-19 (RBB-19) in medium was compared in this study. S. ostrea was more efficient than P. chrysosporium in de-coloration process. Different parameters(More)
