Herbicides and insecticides effects on green algae and cyanobacteria strain
The toxic effects of herbicides (Machete, Saturn) and pesticides (Diazinon and Malathion) on green algae, Scenedesmus obtusiusculus, and cyanobacteria, Anabaena flos aquae, were studied. The results indicated that Machete and Saturn, in comparison to Diazinon and Malathion, were more toxic. On the other hand it was revealed that green algae was more sensitive to the pesticides than the cyanobac...

متن کاملViability of lyophilized cyanobacteria (blue-green algae).
Lyophilizatin of 13 cyanobacterial cultures belonging to seven genera was attempted in a variety of suspending substances. All organisms survived lyophilization when suspended in lamb serum. Some of the organisms could be successfully lyophilized in horse serum, beef serum, fetal bovine serum, or human ascites fluid. With the exception of Nostoc muscorium, none of the organisms survived lyophil...
متن کاملFate of Model Xenobiotics in Calcareous Marine Algae!
Uptake, depuration, and metabolism ofp-nitroanisole (PNA) and p-nitrophenol (PNP) were investigated in Halim eda, Padina, and Porolithon species, all of which are calcareous marine algae found in tropical waters . The algae were exposed to filtered seawater solutions of either PNA or PNP in a static system for 24 hr (uptake period), then placed in clean water and allowed to release absorbed che...
متن کاملAlgae and cyanobacteria in coastal and estuarine waters
In coastal and estuarine waters, algae range from single-celled forms to the seaweeds. Cyanobacteria are organisms with some characteristics of bacteria and some of algae. They are similar in size to the unicellular algae and, unlike other bacteria, contain blue-green or green pigments and are able to perform photosynthesis; thus, they are also termed blue-green algae. Algal blooms in the sea h...
