Title: Modified Cold Percolation Method for Extracting Oil from Oil Seeds Authors: Kalia, V C; Lal, Sadhana; Rashmi Abstract: Oil extraction by different methods like soxhlet, automated soxhlet, sonication, microwave, Super Critical Fluid Extraction (SFE), Accelerated Solvent Extraction (ASE) consume 15 to 500 mL of solvent and average extraction time per sample varies from 12 min to 48 h. Such methods are inconvenient to follow, where a large number of small sized samples are to be processed, in order to detect the small effects of enzymatic treatment. For this purpose, a simplified cold percolation method is quite effective and suitable. However, the extraction period is too small (2 to 3 min) to allow manipulation of oil extraction quantities and rates. In this paper, we present a modified cold percolation method for regulating extraction of oil from oil seeds, particularly suitable for enzymatic studies. Page(s): 630-634

Title: Vaginal Pheromone and Other Compounds in Mung-Bean Aroma Authors: Brahmachary, R L; (Basu), Mahua Ghosh Abstract: This paper reports probably a first attempt to identify the molecules which impart a most desirable, characteristic aroma to certain varieties of mung bean of Bengal — a valuable indigenous natural product that may be on the verge of extinction. In boiled, or fried mung bean of the two best strains, strong evidence for the presence of 2-acetyl-l-pyrroline, the molecule responsible for the aroma of Basmati rice^land one component of tiger pheromone, has been obtained. GCMS analysis and computerized library search further suggested the presence of six volatile compounds in the CCl₄ extracts of even the second grade mung bean samples. Two of these were a male-attracting vaginal pheromone and a puberty-delaying pheromone in rodents. Page(s): 625-629

Potato Phenol Oxidases Immobilized s-Triazine Containing Dialdehyde: An Efficient Biocatalysts For Bioremediation of Phenols

Title: Potato Phenol Oxidases Immobilized s-Triazine Containing Dialdehyde: An Efficient Biocatalysts For Bioremediation of Phenols Authors: Gacche, R N; Ghole, V S; Khobragade, C N; Sagar, A D Abstract: Polyphenol oxidase (PPO) and peroxidase enzymes extracted from potato and immobilized on s- triazine have been exploited for the detoxification of phenols from industrial effluents. It was found that the phenol content of industrial effluent was reduced from 168 to 38 μg/mL within three and half hours treatment with immobilized phenol oxidases. Page(s): 621-624

Soil Physical and Chemical Properties as Influenced by Flyash Addition in Soil and Yield of Wheat

Title: Soil Physical and Chemical Properties as Influenced by Flyash Addition in Soil and Yield of Wheat Authors: Sharma, S K; Kalra, Naveen; Singh, G R Abstract: Field experiments were conducted in villages around National Capital Power Project (NCPP), Dadri, Uttar Pradesh and Indian Agricultural Research Institute (lARI) Farm, New Delhi during 1995-96 to evaluate flyash addition effects on soil environment and yield of wheat crop (Triticum aestivum L.). Flyash application levels were up to 50t/ha. Yield of wheat increased up to 20t/ha ash addition, and declined thereafter but still higher than the yield under no flyash addition treatment. Flyash treated plots had marginally higher uptake of trace elements. Flyash application in soil showed reduced hydraulic conductivity and improved moisture retention at field capacity and permanent wilting point. The pH value of soil decreased, whereas electrical conductivity, organic carbon and sodium increased in accordance with flyash addition in soil. Phosphorous, potassium and calcium decreased in flyash treated plots. The changes in soil properties might be due to modifications in the macro- and micro pore size distribution which contributed to increased yield of wheat. Page(s): 617-620
