  • Lotus seed(Nelumbo nucifera Gaertner), known as traditional medicine as an antifebrile, antipsychotic, and cantihypertensive agent, was analyzed the chemical composition of lipid and protein. The seed com posed of 12.2% moisture, 2.3% crude lipid, 19.5% crude protein, 61.3% carbohydrate, 2.1% crude fibre, and 4.1% ash. The lipid showed iodine value of 97.9 that is lower than that of soybean oil and sesame oil, and similar to peanut oil and cotton seed oil. The fatty acid composition of the oil were the highest in content of linoleic acid which occupied 58.3% and saturated vs unsaturated fatty acid was 20.9:79.1. Especially behenic acid content, 6.9%, was higher than other plant oils. Sixteen amino acids were detected in the protein from the seed and glutamic acid content was the highest as 4.5% in dehulled kernel. The portion of essential amino acid was 31.1%.

  • Twenty-four Harnai lambs 6 to 7 month old, weighing $16{\pm}2kg$ were used in a completely randomized design in growth and digestibility trials to study fourwing saltbush ratio supplemented with cotton seed cake. The animal were divided at random into three groups of 8 animals each. Three iso-nitrogenous (10.5% CP) experimental rations (1, 2 and 3) containing wheat straw + lucerne hay (24:76); fourwing saltbush (Atriplex canescens) + cotton seed cake (71:29); and wheat straw + cottonseed cake (41:59); respectively, were allotted to each group randomly. All the animals were taken out for grazing in a dormant native range for about 3 hours in the afternoon during the growth trial. The growth trial lasted for 8 weeks followed by a digestibility trial. At the end of 8 weeks lambs on ration 3 had gained significantly (p<0.10) more weight compared to those on rations 1 and 2 which maintained their body weight. The crude protein digestibility of the fourwing saltbush based ration was comparable with the other two treatments (71 vs 70 and 71%). However, the digestibility of dry matter (41%), acid detergent fibre (13%) and neutral detergent fibre (22%) of this ration was significantly lower (p<0.10) than the other two diets. The results suggest that lambs can be maintained on fourwing saltbush during winter without significant loss in body weight with 30% extra protein concentrate supplementation.

  • The effect of replacement of cotton seed meal (CSM), with various levels and sources of non-protein nitrogenous (NPN), substances on in vitro ruminal fermentation were studied. Cotton seed meal, in control ration provided nitrogen equivalent to 12.5 percent crude protein while in experimental ration was replaced at 30, 50 & 70 percent levels with urea, diammonium phosphate (DAP) and biuret, respectively. The results of incubation upto 48 hours indicated an improvement in digestibility by replacement of CSM with urea and biuret upto 50 percent protein equivalent, but not with DAP. Bacterial count from cultures containing 50% nitrogen from biuret was significantly higher than DAP, urea and CSM. Various sources of nitrogen produced $NH_3-N$ in increasing order of CSM, biuret, DAP and urea. Increasing levels of NPN resulted in progressive increase in the levels of $NH_3-N$. The levels of various NPN sources had no effect on pH. However, the pH values determined for urea and CSM were higher than biuret and DAP.

  • Ansamitocin P-3 is a potent antitumor agent produced by A. pretiosum. A deletion mutant of A. pretiosum was constructed by deleting the asm2 gene, a putative transcriptional repressor. The deletion mutant showed a 9-fold enhanced ansamitocin P-3 productivity. The response surface method with central composite design was employed to further optimize the culture medium composition for ansamitocin P-3 production by the deletion mutant. The concentrations of four medium ingredients, dextrin, maltose, cotton seed flour, and yeast extract, which have been reported as major components for ansamitocin production, were optimized through a series of flask culture experiments. The optimum concentrations of the selected factors were found to be dextrin 6.0%; maltose 3.0%; cotton seed flour 0.53%; and yeast extract 0.45%. The maximum titer of ansamitocin P-3 was 78.3 mg/l with the optimized composition, about 15-folds higher than the unoptimized titer of 5.0 mg/l obtained with YMG medium.

  • The performance of immobilized fungal cells on celite beads for the production of gibberrelic acid was investigated in flasks and 7-L stirred-tank reactor. Repeated incubations of immobilized fungal cells increased cell concentrations and volumetric productivity. The maximum volumetric productivity obtained in the immobilized-cell culture was 3-fold greater than that in suspended-cell culture. The concentration of cotton seed flour (CSF), among the various nutrients supplied, most significantly influenced productivity and operational stability. Notably, insoluble components in CSF were found to be essential for production. CSF at 6 g/L with 60 g/L glucose was found to be optimal for gibberellic acid production and stable operation by preventing excessive cell growth.

  • 맥후작 면화재배에서 숙기를 단축하고 적채면수량을 증가시키고자 본실험을 실시하였든바 그 결과를 요약하면 다음과 같다. 1) 맥후작 면화재배에서 10월상순 Ethrel를 산포하면 적채면화율이 무처리구의 38%에 비하여 2,000ppm처리구의 그것은 93%였으며 개서는 20일이나 앞당겨 졌다. 2) 수량에서는 무처리구에 비하여 Ethrel처리구가 15%∼38%까지 증수되었다. 3) 한편 섬유장과 섬유장력에 있어서는 처리구는 무처리구와 차이 없었으나 적채면과 목채면간에는 무처리구 및 Ethrel처리구에 있어서 각각 평균 1.3mm 정도 목채면이 더 짧았다. 4) 1삭중과 종자 100립중에서도 Ethrel처리로 인한 차이는 전혀 없었으나 적채면과 목채면간에서는 목채면이 훨씬 가벼웠다. 5) Ethrel로 처리된 적채면종자는 무처리의 그것에 비하여 발아가 촉진되었다. 그러나 목채면종자의 발아율은 철된것이나 안된것이나 바슷했다. 6) 이상의 결과로서 맥후작면화재배에 있어서 만숙장섬유품종을 도입하여도 Ethrel를 적용하면 적채면수량이 더욱 증가된다고 본다.

  • Protein spectra from 6 species of Gossypium were obtained by disc electraphoresis of seed extracts. Protein extracts were made by soaking 0.5g. of seed in 15ml of Tris-glycine buffer for 24 hours. Gels 24 hours. Gels were stained in 0.5% Amido Black solution for 1 hour, and destained in 7% acetic acid for 72 hours. Nine to 15 bands were visible in each gel. Homologies of Protein bands among the species were determined by migration velocity. Evidences obtained from electrophoretic separation of seed Protein were consistent with those from genetic, cytological, morphological and Phenogenetic methods regarding the origin of New World cultivated cottons. Possibility, however, does not exist to exclude Gossypium herbaceum from one of the Progenitors of New World cultivated cottons from electrophoretic evidences alone.

  • Eight feeds (mixture of wheat straw and oil seed cakes in 3:1 ratio) were evaluated for methane emission and fermentation pattern with buffalo rumen liquor as inoculum in an in vitro gas production test. The cakes tested were groundnut cake (GNC), soybean cake (SBC), mustard seed cake (MSC), cotton seed cake (CSC), karanj seed cake expeller extracted (KCEE), karanj seed cake solvent extracted (KCSE), caster bean cake expeller extracted (CBCEE) and caster bean cake solvent extracted (CBCSE). The gas production (ml/g dry matter) was significantly higher with SBC and MSC followed by CSC, GNC, KCSE, KCEE, CBCSE and was the lowest with CBCEE. Methane emission was significantly lower with KCEE, KCSE, CBCEE, CBCSE (20.32- 22.43 ml/g DM) than that with SBC, GNC, CSC (27.34-31.14 ml/g DM). Mustard seed cake was in-between the two groups of oil cakes in methane production. In vitro true digestibility was highest with SBC followed by GNC, CSC, MSC, KCSE, KCEE, CBCSE and CECEE. Ammonia nitrogen level was positively correlated with the amount of protein present in the cake. Total holotrich protozoa were significantly higher with SBC, whereas, large spirotrich protozoa tended to be lower than with other cakes. The counts of small spirotrich and total protozoa were similar with all the cakes. Total volatile fatty acid production and acetate to propionate ratio were significantly higher with SBC and significantly lower with KCEE as compared to the other cakes. Among the conventional oil cakes tested in the present experiment (GNC, SBC, MSC and CSC), mustard seed cake-based feed produced the minimum methane without affecting other fermentation characteristics adversely.
