Paints consist of organic and inorganic nutrients that can stimulate the growth of the microorganism. Many of the components present in paint are biodegradable. Paint is used for the protection of the substrate materials. The purpose of paint is to provide good appearance. Paint is a surface coating polymer based products. It is often discoloured by mould and blue stain, this leads to loss of paints. Biodeterioration arise from interaction among substrate, environment and organisms. The fungi degrade the paint film by producing extracellular enzymes such as ligninase, cellulose and organic acids. The most commonly used method is the addition of antifungal agent in the paint composition, which may acts as a biocide and inhibits the mould growth on paint and painted surface. Therefore the present study was aimed to isolate and identified the mouldy growth on fabric paints especially in green and red colors. The effective control of fungi in the paints was controlled using appropriate antifungal agent. Silver nitrate is very effective in killing fungal species that causes decay and deterioration of paint or paint film even at low concentration.","PeriodicalId":13830,"journal":{"name":"International Journal of Advanced Research in Biological Sciences","volume":"2012 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86390075","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}

Ten A. niger isolates were isolated and studied in the groundnut \u0000cultivated area of Madurai. Groundnut was challenged with Aspergillus, and the production of pectinase and cellulase enzymes \u0000was investigated to assess the virulence of the fungal isolates. Among the ten isolates A. niger CLR10 produced highest \u0000percentage (40%) of diseased plants. Based on the production of these enzymes in groundnut plants challenged with the pathogen \u0000A. niger CLR10 produced highest level of these enzymes so it was used for further studies. The treatment AT13 recorded \u0000minimum percentage mortality (15.9%) and the pathogen only inoculated control recorded 100% mortality. Application of AMF \u0000with rhizobial isolates decreased the mortality in groundnut. The biocontrol studies revealed that the combined inoculation of \u0000AMF and Rhizobium sp. reduced the pathogenesis of A. niger CLR10. However, the treatment AT13 recorded significantly \u0000(p<0.05 and 0.01) higher growth parameters than other treatments. The investigation suggested that inoculation of Glomus \u0000mosseae and Gigaspora albida along with Rhizobium sp.GPMK1 and GMDU1 can improve not only the growth but also render \u0000disease resistance to groundnut. It can be summarized that the practice of multiple inoculation is found more effective as \u0000compared to the traditional practice of single inoculation of inoculums.","PeriodicalId":13830,"journal":{"name":"International Journal of Advanced Research in Biological Sciences","volume":"151 1","pages":"5-15"},"PeriodicalIF":0.0,"publicationDate":"2017-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86281946","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}

Forty two Sprague Dawley male rats were used and randomly distributed into 6 equal groups (n=7). The 1 group was negative control and each rat from the other 5 groups was given a single subcutaneous dose (15 mg/kg b.wt.) of AOM once weekly for 2 weeks to induce colon cancer. The 2 group was kept positive control and rats in the 3, 4, 5 and 6 groups were orally given RJ and AJ at low (5%) and high (10%) concentrations, respectively, daily for 12 weeks. Serum colon cancer biomarkers [(tumor necrosis factor α(TNF-α); nuclear factor-κappaB (NF-κB); interleukin1β (IL-1β) and interleukin and 6 (IL6)] were measured and histopathology of the colon was done to evaluate the anticancer effect. Lipid peroxidation and activities of antioxidant enzymes in colon tissues and content of 8hydroxy-2-deoxyguanosine (8-OHdG) (apoptosis marker) in colon DNA were measured to examine the possible mechanisms. The results showed that oral administration of RJ and AJ inhibited AOM-induced elevations in serum colon cancer biomarkers levels, antagonized preneoplastic abbrent colon crypts induced by AOM, decreased lipid peroxidation; increased activities of antioxidant enzymes in colon tissues and reduced elevation of 8-OHdG content in colon DNA. These results denoted that RJ and AJ have an anticancer effect against colon cancer. The mechanistic studies demonstrated that RJ and AJ inhibited lipid peroxidation, increased antioxidant enzyme activities (antagonized oxidative stress) and induced of apoptosis. It can be concluded that intake of black raspberry and apricot as fruit salad or juice may be beneficial for patients who suffer from colon cancer.","PeriodicalId":13830,"journal":{"name":"International Journal of Advanced Research in Biological Sciences","volume":"1 1","pages":"187-196"},"PeriodicalIF":0.0,"publicationDate":"2017-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86182399","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}
