“…In Cyanobacteria, reports suggested indication of SOD, catalase or some peroxidases under conditions of oxidative stresses based on activity measurements (Mittler and Tel-Or, 1991;Abeliovich et al, 1974). The activity of antioxidative enzymes-Superoxide dismutase, Peroxidase catalase, and Ascorbate Peroxidase has also been reported from marine cyanobacterium O. willei BDU 130511 (Saha et al, 2010). The enzymes involved in antioxidative activity and the cellular content of the antioxidants glutathione and ascorbate in the cyanobacteria N. muscorum 7119 and Synechococcus 6311 has been examined for their roles in hydroperoxide removal.…”

Abstract:The antioxidative enzymes catalase and ascorbate peroxidase in toxic bloom forming cyanobacteria play a pioneer role in scavenging free radicals, which are generated as an outcome of photosynthesis and respiration. Ten Bloom forming toxic cyanobacterial strains Synechococcus elongates, Synechocystis aquatalis, Merismopedia glauca, Microcystis aeruginosa, M. aeruginosa (O), Arthrospira (=Spirulina) platensis, Nostoc paludosum, Anabaena iyengarii, A. variabilis and Cylindrospermum muscicola were isolated from natural blooms and purified. The results depict the significant activity of antioxidative enzymes. In A. platensis the activity of catalase (28.7 ± 2.3 mM/ min/μg protein), and Ascorbate peroxidase (1.91±0.12 mM/min/μg protein) enzyme was maximum. It was also observed that the activity of ascorbate perooxidase was very less compared to activity of catalase. The growth analysis and pigment profile were also studied. Growth measurements revealed that cells attain maximum growth nearly after 15-20 days of inoculation except S. aquatalis, A. platensis and N. paludosum maximum, where optimum growth was achieved after 25 th day. Chlorophyll-a content of A.platensis showed maximum concentration (14.47 ± 1.17 mg/L) and minimum concentration in S. elongates (2.30 ± 0.138 mg/L). The concentration of phycobiliproteins was found maximum in A. platensis (2.09 mg/ml). The detection of antioxidative potential of cyanobacterial strains will help to broaden the knowledge about their survival and can pave path for their utilization in biotechnology.

“…CAT decomposes H 2 O 2 into O 2 and H 2 O (Tongul and Tarhan, 2014). It reported previously that NADH oxidase catalyzed the reduction of O 2 to O 2 À (Saha et al, 2010). H 2 O 2 accumulation in the PTNs is associated with an increased NADH oxidase activity.…”

The aim of the present work is to study the growth and effluent parameters of the two ossein effluents. Growth parameters studied in this article are protein, chlorophyll, carbohydrate, moisture and the effluent parameters are alkalinity, nitrates, nitrites, ammonia, phosphates, sulphates, sulphites, calcium and magnesium. Calcium-rich effluent ossein was collected at three different clarifications stages from pioneer Jellice Industries Pvt, Ltd,, Cuddalore, which is gelatin manufacturing industry. The algae selected for the study was chlorella vulgaris BDU G91771 which was obtained from the culture collection of National Facility for Marine Cyanobacteria (NFMC), Bharathidasan University, Tiruchirapalli, India. The culture was maintained in F/2 medium under the continuous white light at an intensity of 20 μmol photon m-2 s-1 at 25 ± 2 ºC in a controlled culture room. The chosen organisms were grown in effluent diluted with seawater (1:1, 2:2 and 3:1) amended with fertilizer grade nutrient enrichment and phosphorus sources. The untreated effluent parameters were analyzed. Chlorella vulgaris was inoculated in F/2 medium and allowed to grow in ossein effluent for 7 days. The growth of the organism was measured by calculating its culture density, dry weight, carbohydrate, protein and chlorophyll. The growth parameters of microalgae revealed that the higher content of nitrate and ammonia in HTDS effluent served as the nitrogen source and supported microbial growth.
