Abstract

In the recent period, the classification techniques are widely applied in the field of Bioinformatics. The proposed Amino Acid Component based Classification algorithm adopts Iterative Dichotomiser3 classifier. The algorithm consists of two phases viz. attribute selection and component based classification. In the attribute selection phase the dominating amino acids and deficiencies in amino acids that cause the diseases are found. The second phase finds the components of amino acids which spread the diseases in the specified sequence. The experiments were carried out on the gene sequence of dengue virus which is available on the NCBI online biological database and the accuracy of the proposed algorithm is calculated as 90.744%. The proposed classification algorithm is compared with the traditional benchmark algorithms such as Naive Bayes, ID3, Random Forest, Multilayer Perceptron and J48. The result of this work can be used by the drug designers to predict new viral diseases.

Abstract

Nine mutants of Trichoderma viride Pers. ex Fr. obtained by using different mutagenic agents were evaluated for their relative efficacy against Macrophomina phaseolina (Tassi.) Goid in terms of antibiotic production. The cell free culture filtrate of mutant M 1 showed the highestin vitro inhibition of mycelial growth (54.4%) and sclerotial germination (75.8%) of M. phaseolina followed by M3 and they were on par with each other. The mutants M3 and M8 produced maximum volatiles in vitro as evidenced by the retardation in growth of M. phaseolina which registered a growth of 10 mm after 48 h of incubation while in control the growth was 90 mm.

Abstract

Seedvine rot is one of the major problems of betelvine cultivation. Dipping of betelvine seedvine in Azospirillum suspension before planting resulted in 100 per cent ischolar_maining in 14 days of planting and reduced the seedvine rot by 84 per cent under field conditions. The association of Azospirillum with the ischolar_mains of betelvine is established.

Abstract

The core objective of this paper is to analyze the Dengue Serotypes using online biological databases & tools and to generate a novel gracious tool to carry out sequence analysis using bioinformatics algorithms and concepts on Dengue virus sequences or other organisms that will be helpful in attaining knowledge for new invention. The Dengue virus is a member of the family Flavi virus. It is transmitted to people through the bite of the mosquitoes “Aedes aegypti" and “Aedes albopictus”. Dengue virus is now believed to be the most common anthropod-borne disease (an infectious disease carried by insect vectors) in the world and the Dengue fever is also called as “Break Bone Fever”. Dengue is mainly found in the tropics because the mosquitoes require a warm climate. A major fear of epidemiologists is that the mosquitoes will develop resistance to cooler climates and then be able to infect people living in any climate. Predicting the relationship between Dengue Serotypes will definitely help the Biotechnologists and Bioinformaticians to move one step forward in discovering vaccine for Dengue. For that the tool “Sequence Miner” created with computational intelligence is much helpful. Computational intelligence comprises practical adaptation concepts, paradigms, algorithms and implementations that enable or facilitate appropriate actions (intelligent behavior) in complex and changing environment.

Abstract

To evaluate the decolourisation efficiency of metals, platinised titanium, mild steel, aluminium, stainless steel and copper were used as anodes for decolourization of dye effluent solution. Declorization efficiency was calculated before decolorization and after decolorization. The result of this investigation study reveal that the % of decolorization efficiency of various anodes are in the following decreasing order.
platinised titanium>copper>aluminium
