    Bio-softening of mature coconut husk for facile coir recovery
    (2007) Suganya, D.S.; Pradeep, S.; Subramanian, S.; Jayapriya, J.
    Bio-softening of the mature coconut husk using Basidiomyceteous fungi was attempted to recover the soft and whiter fifi bers. The process was faster and more effifi cient in degrading lignin and toxic phenolics. Phanerochaete chrysosporium, Pleurotus eryngii and Ceriporiopsis subvermispora were found to degrade lignin effifi ciently without any appreciable loss of cellulose, yielding good quality fifiber ideal for dyeing.

    Eradication of fishes by application of ammonia
    (1983) Subramanian, S.
    A simple method is described for the eradication of undesirable fishes from fish culture ponds by application of ammonia. Modifying an earlier technique of direct injection of anhydrous ammonia, a trial was carried out in which ammonia was released by the application of solutions of calcium hydroxide and ammonium sulphate in a ratio of 1:1.8. Ammonia at a concentration of 15 ppm (12.4 ppm N) killed plankton, minnows and predatory fishes including the air breathing species. The advantages of the method are discussed.
