Considerable enzymological diversity underlies the capacity for biosynthesis of aromatic amino acids in nature. For this biochemical pathway, higher plants as a group exhibit a uniform pattern of pathway steps, compartmentation, and catalytic, physical and allosteric properties of enzymes. This biochemical pattern of higher plants contains a collection of features which are completely different...

BACKGROUND The utilization of biomass from microalgae for biofuel production is one of the key elements for the development of a sustainable and secure energy supply. Among the different microalgae, Chlorella species are of interest because of their high productivity, high lipid content, and resistance to the high light conditions typical of photobioreactors. However, the economic feasibility o...

BACKGROUND Lung cancer is one of the leading causes of cancer related deaths worldwide. Marine microalgae are a source of biologically active compounds and are widely consumed as a nutritional supplement in East Asian countries. It has been reported that Chlorella or Chlorella extracts have various beneficial pharmacological compounds that modulate immune responses; however, no studies have inv...

Identifying the newly isolated species is crucial to establishing a reliable algal database with successful commercial applications for different biotechnological applications. Morphological identification does not give sufficient description, especially tiny unicellular microalgae. The rbcL gene encodes large unit of ribulose-1, 5-bisphosphate carboxylase /oxygenase (Rubisco) has been widely k...

Based on the ability of microalgae to purify industrial processing waters, overall aim this study was evaluate whether currently wasted shrimp waters could be used as microalgal growth media produce new protein-enriched food and feed ingredients. Low molecular weight (LMW) fractions boiling water (SBW) which had been pre-flocculated using alginate (AL), carrageenan (CA), chitosan (CH) or Superf...

Some Effects of Light Intensity and Oxygen Concentration on Chlorella sorokiniana and an Oxygen Resistant Strain by Sylvia Staehle Morhardt. Experiments were carried out to compare the thermotolerant unicell¬ ular green alga Chlorella sorokiniana and an oxygen resistant strain isolated from the species. Studies were made at 39°C over a range of light intensities from about 600 to 4200 ft-c. usi...

We recently developed a chlorophyll fluorescence method (activated F0 rise) for estimating if light wavelength preferably excites PSI or PSII in plants. Here, the was tested green microalgae: Scenedesmus quadricauda, ecornis, fuscus, Chlamydomonas reinhardtii, Chlorella sorokiniana, and Ettlia oleoabundans. The species displayed plant-like action spectra of rise, suggesting that PSII/PSI absorp...
