Study on Induced Fermentative Methodology for the Production of Virgin Coconut Oil from two Cocos nucifera Varieties

In this study, Virgin Coconut Oil (VCO) was produced from West Coast Tall (WCT) and Deejay Coconuts (DJ) under induced fermentative methodology by employing Saccharomyces cerevisiae and Lactobacillus plantarum (9511) strains. This production methodology was optimized with temperature, PH, Inoculum concentration and Fermentation end time. The VCO yielding efficiencies were compared from two strains. Among the four parameters in the study, the maximum yielding efficiencies were obtained from WCT coconuts employing L. plantarum (9511) at 40±1ºC temperature, 5.5±0.1 PH, 7% (w/v) Inoculum concentration and 60hrs of fermentation end time. In conclusion, it has been observed that proximate analysis of VCO showed within the standard limits and also WCT Coconuts in combination with L. plantarum offered higher yield and better fatty acid proportion than the DJ Coconuts. &nbsp

Videogame Playing and Aggression Behaviour: A Correlation Study among School Students

The purpose this study is to explore school students' videogame playing and its correlation to aggressive behaviour. Four hundred and six (406) videogame playing students from different socio-economic background in Chennai city of India and its suburban areas participated in the study. Data on aggressive behaviour from the students were collected in the Buss and Perry Aggression Questionnaire format. The General Aggression Model was used to predict the students' aggression. The study reveals that gender was significant in hostility, physical and verbal aggression. Further, analyses indicated that parents' education has a significant bearing on students' aggression behaviour

Optimization of Process Variables for the Production of Virgin Coconut Oil from Selected Cocos Nucifera Varieties under Fresh-Dry Method

Virgin Coconut Oil (VCO) was prepared from four coconut varieties viz., West Coast Tall, Arasampatti Tall, Deejay and Tiptur Tall. The Fresh-Dry methodology was optimized by three common variable parameters like temperature viz., 30±1ºC, 35±1ºC, 40±1º C, 45±1ºC, Drying intervals viz., 24hrs, 36hrs, 48 hrs, 60hrs and fruit maturity like 10, 11, 12 and 13 month old coconuts was taken to estimate the yielding efficiency of VCO .The yielding efficiencies are calculated from the four Coconut varieties by comparing the total percentage of Oil extracted from Soxhlet method. Among the four, the maximum yielding efficiency 95.33% was obtained in WCT Coconuts drying with 45º C. In the second process variable, where the maximum yield efficiency was showed that is 93.06% with 48 hrs drying. The third process variable showed the same maximum value of 93.06% as in second process variable by employing 12 month old coconuts The coconut varieties are taken in this research study, showed different yield composition of fatty acid profile especially the lauric acid percentage, which was registered maximum that is 51.20% at “WCT Coconuts” and in other coconut varieties such as AT, DJ and TT Coconuts were noted as 50.10%, 49.23% and 48.55% respectively. &nbsp

Species Discrimination, Population Structure and Linkage Disequilibrium in Eucalyptus camaldulensis and Eucalyptus tereticornis Using SSR Markers

Eucalyptus camaldulensis and E. tereticornis are closely related species commonly cultivated for pulp wood in many tropical countries including India. Understanding the genetic structure and linkage disequilibrium (LD) existing in these species is essential for the improvement of industrially important traits. Our goal was to evaluate the use of simple sequence repeat (SSR) loci for species discrimination, population structure and LD analysis in these species. Investigations were carried out with the most common alleles in 93 accessions belonging to these two species using 62 SSR markers through cross amplification. The polymorphic information content (PIC) ranged from 0.44 to 0.93 and 0.36 to 0.93 in E. camaldulensis and E. tereticornis respectively. A clear delineation between the two species was evident based on the analysis of population structure and species-specific alleles. Significant genotypic LD was found in E. camaldulensis, wherein out of 135 significant pairs, 17 pairs showed r2≥0.1. Similarly, in E. tereticornis, out of 136 significant pairs, 18 pairs showed r2≥0.1. The extent of LD decayed rapidly showing the significance of association analyses in eucalypts with higher resolution markers. The availability of whole genome sequence for E. grandis and the synteny and co-linearity in the genome of eucalypts, will allow genome-wide genotyping using microsatellites or single nucleotide polymorphims
