During chronic exposure to sodium fluoride, the banding pattern of esterase diminished in the treated group of fish viz. lowest (5.75 ppm), lower intermediate (7.18 ppm), higher intermediate (9.58 ppm) and highest (14.37 ppm) concentration of the 24 hrs. LC 50 (115 ppm) value when compared with the control group. SDS-PAGE and staining of the gel revealed that esterase in muscle of fish from control group resolved into six bands (lane-1). Exposure of fluoride to all the four concentrations showed significantly faint and diffused banding pattern of esterases and complete loss of esterase band-1 (Lane 2-5), probably due to chronic stress induced by fluoride. The esterase from band-1 might be sensitive to fluoride intoxication, thus completely vanished during chronic treatment. However in the higher intermediate (9.58 ppm) and highest (14.37 ppm) sodium fluoride treatment groups, sixth band of esterase (lane 4-5) was found to be very faintly visible on staining. Decrement in protein content & diminution of certain esterase bands in the muscle tissue of the treated group suggest soft tissue (non-skeletal) fluorosis induced by sodium fluoride during chronic exposure period, probably could be due to inhibition of biosynthetic mechanism of proteins vis-a-vis esterases. The study of esterase in fish calls attention to sensitive indicator of the environmental pollutants and can be used as contrivance in study of environmental dilapidations.

The internodal explants from A. nilagirica were cultured on Murashige and Skoog’s (1962) basal medium (MS) supplemented with various concentrations and combinations of plant growth regulators. A synergistic coupling of 0.5 mg/L 2,4- dichlorophenoxyacetic acid (2,4-D) with 1.0 mg/L Kinetin (Kin) yielded maximum callogenic response. Shoot organogenesis in callus cultures was most favoured in MS containing 2.0 mg/L 6-benzylaminopurine (BAP) and 0.5 mg/L indole-3-acetic acid (IAA). In vitro regenerated plantlets, emerged from culture medium, were acclimatized and the survival rate of ex vitro plants after soil transplantation was 80-83% with no apparent phenotypic variations. The antioxidant potential of natural (in vivo) plants, callus tissues and in vitro regenerated plants before and after field transplantation (ex vitro) plants were compared. DPPH scavenging activity was the highest in aqueous extracts of 10 week-old ex vitro plants than other sources. Superoxide anion and nitric oxide radical scavenging activity was the highest in ethanolic extracts of 10 week-old ex vitro plants where as the hydroxyl radical was the maximum in 6 week-old in vivo plants. Lipid peroxidation was neither observed in calli nor in regenerated plants of A. nilagirica.","PeriodicalId":18074,"journal":{"name":"LIFE SCIENCES LEAFLETS","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85267279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ligninolytic white-rot basidiomycetes can effectively degrade colored effluents and conventional dyes. White-rot fungi produce various isoforms of extracellular oxidases including laccase, Mn peroxidase and lignin peroxidase (LiP), which are involved in the degradation of lignin in their natural lignocellulosic substrates. The textile industry, by far the most avid user of synthetic dyes, is in need of eco-efficient solutions for its colored effluents. White rot basidiomycetous fungi comprise the only group of organisms known to completely degrade lignin. Ligninolytic enzymes have potential applications in a large number of fields, including the chemical, fuel, food, agricultural, paper, textile, cosmetic industrial sectors and more. This ligninolytic system of white-rot fungi is also directly involved in the degradation of various xenobiotic compounds apart from textile dyes. Their capacities to remove xenobiotic substances make them a useful tool for bioremediation purposes. This paper reviews involvement of ligninolytic enzymes of white rot basidiomycetes in the degradation of textiles dyes and xenobiotic compounds for their industrial and biotechnological applications.","PeriodicalId":18074,"journal":{"name":"LIFE SCIENCES LEAFLETS","volume":"30 1","pages":"62-75"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84184206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
