Ornamental plants are cultivated for adornment and to enhance the appearance of houses and also for commercial purposes. However, only very few of these ornamental plant species have found to be used in medicine and only little literature exit on their chemical and biological actions. In the present study, the evaluation of antimicrobial activities and identification of bioactive compounds using TLC and GC-MS of the A. columnaris bark extract were performed. In GC-MS bioactive compounds with medicinal value were identified, such as Benzoic acid, 1H-N-Hydroxynaphth (2,3) imidazole-6,7-dicarboximide, 2-Propenoic acid, 3-(4-methoxyphenyl), 1H-N-Hydroxynaphth (2,3-d) imidazole-6,7-dicarboximi. To prove the nontoxic nature of the plant, its crude bark extract was subjected to toxicity study using human embryonic kidney cell line. It reveal that the plant is minimal toxic to the human kidney cell line so usage of appropriate level will found to be safe and also carrying out some structural modification will help in the extraction of new drugs for pharmaceutical purpose.","PeriodicalId":274901,"journal":{"name":"Asian Journal of Biotechnology","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131932193","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}

Most of the fermented food products are known and proven for its high content GABA producer, which makes the food product as potential functional foods. Lactic acid bacteria possess special physiological activities and are generally regarded as safe. This study was aimed at evaluating GABA production ability of some lactic acid bacteria strains isolated from Egyptian dairy products and further to increase the production by combining the best GABA producers. The impacts of pH, temperature, incubation time, initial monosodium glutamate (MSG) concentration and pyridoxal-5’-phosphate (PLP) addition on growth and γ-aminobutyric acid production were investigated. By optimizing these factors at pH5, cultivation temperature of 35°C, cultivation time of 72 h in medium supplemented with 750 M of MSG and 200 μM of PLP, Lactobacillus brevis NM101-1 and Lactobacillus plantarum DSM749 accumulated 168.58 and 140.69 mM of GABA, respectively. Co-culturing of both strains was not only able to enhance GABA production but also producing it in a short time (48 h), reached 224.69 mM. It could be concluded that the use of LAB strains in combination with a high GABA producer strain is a successful approach for reaching a physiologically active concentration of GABA.","PeriodicalId":274901,"journal":{"name":"Asian Journal of Biotechnology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122992585","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}

Control of BBTV involves the use of disease free planting material and prevention of infection. Its accurate detection is one of the functional approach to control it by eradication and exclusion. PCR is the most efficient mode of indexing but high-quality of DNA is one of the most essential factor for a successful amplification by PCR. In this study, we have developed a highly efficient low cost and rapid DNA extraction method for banana tissue which could yield good quantity of DNA free from protein and polysaccharide contamination. The DNA extracted by this method could be successfully amplified by PCR.
