Industrial manufacture generated many kinds of pollutants specially dyes pollutan. Some of those pollutans are toxic, persistent, and becoming more dangerous. Alternative treatment of waste water using microbe capable of biodegrading alizarine, o-phenanthroline, malachiet green, eosine, methyleen blue and yellow methanil had been investigated. Microbes isolated from soybean sludge were inoculat…
The effect of the nutrient nitrogen sources ammonium nitrate, ammonium chloride and potassium nitrate in the media, on the biomass and sapogenius production in the callus cultures of Agave amaniensis were studied. Combining the nutrate and ammonium ions in the media, produced relatively higher biomass, whilst using ammonium or nitrate ions only seemed to inhibit the growth of these callus cultu…
Finding new substances from natural resources is quite important, especially those possessing medical usage. This experiment was perfomed in order to isolate and elucidate the stucture of pentacyclic triterpene and sterol substances from Eupatorium in lifolium H.B.K. leaves. The structural elucidation of those substances was performed using IR, UV, mass spectrometer 1H and 13C NMR. The result s…
