Molecular techniques are used today in many areas and have increased the confi dence level of studies. Th e aim of the study was to compare the classical morphological characters of coccoid green algae under fi eld and culture conditions by using modern molecular analysis. To achieve this aim, we fi rst isolated the coccoid green algae from Liman and Cernek lakes. Th e morphological variations ...

Blue-green algae, scientifically known as Cyano single-celled organisms that grow naturally in fresh not algae (eukaryotes), but are a type of bacteria the ability to synthesize chlorophyll a. Therefore, th sunlight to manufacture carbohydrates from carb process known as photosynthesis. Blue-green al pockets inside vacuoles within their cells that they in regulate their buoyancy in response to ...

Because of limitations of production of unicellular green algae (especially in large volumes), this study aimed to culture Artemia using three sources of cheap agricultural by-products that were coupled with small amounts of unicellular algae Dunaliella salina. The results of growth and survival, biomass production, Individual wet weight, wet and ash percent, FCR and SGR and nutritional value o...

Tropical coastal marine ecosystems including mangroves, seagrass beds and coral reef communities are undergoing intense degradation in response to natural and human disturbances, therefore, understanding the causes and mechanisms present challenges for scientist and managers. In order to protect our marine resources, determining the effects of nutrient loads on these coastal systems has become ...

Those who have observed large numbers of eggs of the spotted salamander (Amnbystorna maculatum) have undoubtedly seen many masses colored a delicate or even a vivid green. The color of these egg masses is due to unicellular green algae which thrive in the egg envelopes, eventually giving to the jelly a green appearance. Often the algal growth, especially within the innermost jelly envelope, is ...

Action spectra for delayed light production by several algae were determined from 250 to 750 mmicro incident light. In the visible portion of the spectrum the action spectra resemble those reported by previous workers for photosynthesis and light emission. Blue-green algae had a maximum at 620 mmicro, red algae at 550 mmicro, whereas green and brown algae have action spectra corresponding to ch...

The green algae and land plants form a monophyletic lineage (the chlorophytes) that contains both protistan and higher taxa (Graham, 1996). An important issue regarding the evolution of this green lineage that still remains in question is the identity of the green algal (i.e. flagellate) ancestor of land plants. Modern molecular phylogenetic data provide the framework for reconstructing this ev...

Background and Aim: Antibacterial effects of Artemisia plant and algae have been confirmed. The purpose of this study was to evaluate the antibacterial effect of antibiotics, Spirulina blue-green algae and Artemisa aucheri leaf extracts on multidrug resistant (MDR) Klebsiella pneumoniae. Materials and Methods: Disk and well diffusion method, the growth minimum inhibitory and bactericidal concen...

A wide range of microorganisms was tested to determine their sensitivity to low concentrations of bisulfite-sulfite and nitrite, solubility products of SO2 and NO2, respectively. Photosynthesis by blue-green algae (cyanobacteria) was more strongly inhibited by 0.1 mM bisulfite-sulfite and 1 mM nitrite at pH 6.0 than photosynthesis by eucaryotic algae and respiration of bacteria, fungi, and prot...
