An actinomycete producing L-3,4-dihydroxyphenylalanine from L-tyrosine. Journal of Biosciences. 1979 Jun; 1(2): 235-239.http://imsear.searo.who.int/handle/123456789/159969An actinomycete was isolated during a soil screening programme to obtain L-3,4-dihydroxyphenylalanine producers. A mutant of this organism was isolated by chemical mutagenesis and it accumulated 1 g/litre L-dihydroxyphenylalanine when grown on L-tyrosine. Resting cells converted 30% of tyrosine in the reaction mixture. The use of resting cells for dihydroxyphenylalanine production is advantageous as it eliminates interfering substances which accumulate during fermentation.enActinomyceteL-dihydroxyphenylalanine productionfermentationArticle
