Studies on the mycoflora of Aswan High Dam Lake, Egypt: vertical fluctuations.

abstract：:The close linkage between hisI and mutations of the cysII group in Pseudomonas aeruginosa was confirmed by mapping experiments with new mutants. All mutants of the cysII group were blocked in the cysteine biosynthesis before sulfite (this include the mutant cys-5605 which had previously been mapped by Mee and Lee, 196...
