| removal efficiency of the heavy metals zn(ii), pb(ii) and cd(ii) by saprolegnia delica and trichoderma viride at different ph values and temperature degrees. | the removal efficiency of the heavy metals zn, pb and cd by the zoosporic fungal species saprolegnia delica and the terrestrial fungus trichoderma viride, isolated from polluted water drainages in the delta of nile in egypt, as affected by various ranges of ph values and different temperature degrees,was extensively investigated. the maximum removal efficiency of s. delica for zn(ii) and cd(ii) was obtained at ph 8 and for pb(ii) was at ph 6 whilst the removal efficiency of t. viride was found t ... | 2007 | 24015084 |
| reprint of: saprolegnia strains isolated from river insects and amphipods are broad spectrum pathogens. | saprolegnia species are destructive pathogens to many aquatic organisms and are found in most parts of the world. reports based on phylogenetic analysis suggest that saprolegnia strains isolated from aquatic animals such as crustaceans and frogs are close to saprolegnia strains isolated from infected fish or fish eggs and vice versa. however, it has often been assumed that host specificity occurs for each individual isolate or strain. here we demonstrate that saprolegnia spp. can have multiple h ... | 2014 | 25088072 |

| comparative study of the effect of stress by the heavy metals cd+2, pb+2, and zn+2 on morphological characteristics of saprolegnia delica coker and dictyuchus carpophorus zopf. | the effects of essential (zn+2) and non-essential (cd+2 and pb+2) heavy metals on morphogenesis of two represantatives of informal group zoosporic fungi namely; saprolegnia delica coker and dictyuchus carpophorus zopf. were studied. these two species varied in their tolerance of each amended heavy metal. lead had the most potent effect amongst the tested heavy metals in inhibiting the radial extension of the vegetative hyphae of the two tested species. the vegetative hyphae of s. delica and d. c ... | 2007 | 18254496 |
