Phenolic profiling and antioxidant capacity of Morchella esculenta L. by chemical and electrochemical methods at multiwall carbon nanotube paste electrode Javed Ahmad Wagay, Gulzar Ahmad Nayik, Sajad Ahmad Wani, Rouf Ahmad Mir, Mir Ashfaq Ahmad, et al. Journal of Food Measurement and Characterization, 2019 The present investigation was carried out to know the aboriginal usage of Morchella esculenta L. as an ethnomedicinal food by tribals of Kashmir, an extreme northern state of India for curing of arthritis, osteoporosis, general bone weakness and cure child labour pain and post menopause pain of women. The average long-life expectancy (~ 80 years) and delayed aging ensured the abundant use of M. esculenta L. as the bases of their daily foods as well as their traditional medicine. The antioxidant character of this mushroom was carried out by chemical and electrochemical assays. The chemical assay was done by DPPH, nitric- oxide, super-oxide scavenging and reducing power while as, electrochemical assay was done by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) using multi-wall carbon nanotube paste electrode (MWCNTPE) at 0.02 M acetate buffer (pH 4.5). The phenolic profiling of the mushroom was evaluated through Folin–Ciocalteu reagent using gallic acid/ascorbic acid as standard which were qualified and quantified by HPLC-UV technique, respectively. The IC50 values found were 57.02 µg ml−1, 58.02 µg ml−1 and 40.01 µg ml−1 for DPPH, nitric-oxide and superoxide. The electrochemical results have shown one oxidation potential at 1.12 V and positive potential at 1.119 ± 0.01 V in CV and 1.19 V in DPV. DPV at superoxide radical scavenging level of mushroom at dropping mercury electrode (DME) in 0.1 M KCl, produced a reduction peak potential at − 0.160 V. HPLC-UV have confirmed the presence of eight phenolic compounds namely, p-coumaric acid, tocopherol, catechol, rutin, hyperoside, quercetin, ellagic acid and cinnamic acid with quercetin at highest percentage (169.76%).
Cellulase production by Bacillus subtilis M1 using pretreated groundnut shell based liquid state fermentation A. Vyas, Chayanika Putatunda, J. Singh, D. Vyas Biotropia, 2016 Groundnut shell which is rich in natural cellulose was assessed as a substrate for production of cellulase enzyme by cellulolytic bacteria. In the present investigation the bacterial isolate Bacillus subtilis M1 was found to be capable of producing high amount of endoglucanase and exoglucanase on alkali treated groundnut shell. The effect of some nitrogen sources, amino acids and Ca++ ionsin the medium containing pretreated groundnut shell were also evaluated. It was observed that 2% substrate concentration, 1mM calcium concentration were optimum for cellulase production. Ammonium nitrate was found to be the best among nitrogen sources tested. Asparagine, tryptophan and methionine were found to be stimulatory for cellulase activity. Keywords: Bacillus subtilis , cellulase, endoglucanase, exoglucanase, groundnut shell
Partial characterization of cellulase production by Jeotgalibacillus marinus MTCC 6233 Ashish Vyas, Chayanika Putatunda, Deepak Vyas Biosciences Biotechnology Research Asia, 2015 Cellulases form a very important group of enzymes which find application in a wide array of processes including production of bioethanol from lignocellulosic materials, biopulping, textile processing, as additives in animal feeds and laundry detergents etc. In the present research investigation, Jeotgalibacillus marinus MTCC 6233 was isolated from decomposing cellulosic waste material. The isolate was further screened and characterized for production of cellulases. The bacterial strain was found to be a potent producer of endoglucanase, exoglucanase as well as β –glucosidase. Highest production of all the three cellulolytic enzymes was observed at 6th day of incubation. Activity of all the three enzymes was found to be optimum at pH 6 and temperature 500 C. Endoglucanase activity was found to be inhibited by 2,4-Di Nitro Phenol (2,4-DNP) and HgCl2. Thus, the isolate Jeotgalibacillus marinus MTCC 6233 can be further assessed for these enzymatic activities and may prove to be a potential candidate for production of various cellulolytic enzymes at commercial scale.
