Effect of cobalt on growth, pigments and the photosynthetic electron transport in Monoraphidium minutum and Nitzchia perminuta
A reduction in the amount of O2 evolved by each alga in response to increasing Co2+ concentrations showed an increase in O2 evolution for both M. minutum and N. perminuta, while the effect of the heavy metal on respiration showed that higher Co2+.
Effect of two species of cyanobacteria as biofertilizers on some metabolic activities, growth, and yield of pea plant
Blue green algae analyses show that N. entophytum fixed more N, produced more exopolysaccharide, and contained more auxin and cytokinin than O. angustissima, the latter contained more gibberellins, which may explain their different influences on growth and yield of pea.
Growth and heavy metals removal efficiency of Nostoc muscorum and Anabaena subcylindrica in sewage and industrial wastewater effluents.
It was observed that the single cultures in most cases was better than the mixed cultures in heavy metal removal, this may be due to the cyanobacterial competition for nutrients in mixed cultures.
Biodegradation of dyes by some green algae and cyanobacteria.
Basic cationic and basic fuchsin were the most susceptible dyes for decolorisation and removal by all algae being tested, and up to ∼82% of methyl red was also removed by N. lincki and O. rubescens.
Bioremediation of different types of polluted water using microalgae
The present investigation was attempted to reduce the toxic pollutants from the different mixtures of water samples (sewage, sea and well) using the freshwater alga, Chlorella vulgaris and the marine
Biodegradation of crude oil by Scenedesmus obliquus and Chlorella vulgaris growing under heterotrophic conditions
It was found that Scenedesmus obliquus and Chlorella vulgaris performed the highest biodegradation rate of crude oil when 0.5 and 1% oil was applied.
Differential effects of Co(2+) and Ni(2+) on protein metabolism in Scenedesmus obliquus and Nitzschia perminuta.
Growth, morphological changes, amino acid composition, total soluble protein, and protein electrophoretic pattern were monitored for Scenedesmus obliquus and Nitzschia perminuta grown in the presence
Comparative Studies on the Green Algae Chlorella homosphaera and Chlorella vulgaris with Respect to Oil Pollution in the River Nile
Although DNA and RNA responded similarly to crude oil inthe two tested organisms, DNA showed more sensitivity than RNA to solar oil, and Lubricating oil had a little phytotoxic effect onnucleic acids.
Stable Transformation of the Intact Cells of Chlorella Kessleri with High Velocity Microprojectiles
A transgenic expression system of Chlorella kessleri using the gene for β-glucuronidase (GUS) was developed and stable transformants were able to grow on kanamycin containing medium after repeated passages between selective and nonselective medium and exhibited GUS activity comparable to that of control cells.
Effective technological pectinases by Aspergillus carneus NRC1 utilizing the Egyptian orange juice industry scraps.
Abstract The production of a notable and highly effective pectinase by the local fungal strain Aspergillus carneus NRC1 utilizing the abundant Egyptian orange peels and pulps (OPP) scraps excluded in
