Two native diatom isolates belonging to the genus Nitzschia, TAMU-LBK-020 and TAMU-LBK-023, were grown in a chamber simulating summer temperatures and light:dark cycle in the southwest Texas (USA) desert. Different concentrations of macronutrients (Si, N, and P) were tested to identify conditions conducive to growth. Growth rates of the fastest growing(More)
The object of this study was to determine the growth rate and biochemical composition of the diatom Nitzschia perspicua cultivated with five Si and two Ni concentrations (which we will refer to as treatments) during a “growth” and “lipid” phase (GP and LP). The studies multi-factorial experimental design will provide information on the biochemistry of lipid(More)
Nitzschia sp. (Bacillariophyceae) was grown under temperature and photoperiods mimicking those, typical during summer, spring/fall and winter conditions in the southern United States, and using five silicate (Si) concentrations. In general, higher Si concentrations resulted in higher growth rates in summer and spring/fall conditions and lower organic(More)
To understand the potential of Nitzschia spp. in the biofuels industry, growth characteristics and fatty acid composition of three strains of Nitzschia grown at five silicate concentrations were investigated. The algae were grown in two stages with temperatures and light: dark cycles designed to mimic spring/fall conditions in the southern United States.(More)
