“…Beyond 25°C, thermal stress was clearly evident. This finding is consistent with the results of Parker et al. (2007), who reported that optimum growth temperatures for the temperate benthic microalga, C. sublittoralis in culture were within the range of 18°C–25°C.…”

Temperature and irradiance are the most important factors affecting marine benthic microalgal photosynthetic rates in temperate intertidal areas. Two temperate benthic diatoms species, Amphora cf. coffeaeformis (C. Agardh) Kütz. and Cocconeis cf. sublittoralis Hendey, were investigated to determine how their photosynthesis responded to temperatures ranging from 5°C to 50°C after short-term exposure (1 h) to a range of irradiance levels (0, 500, and 1,100 μmol photons · m(-2 ) ·( ) s(-1) ). Significant differences were observed between the temperature responses of maximum relative electron transport rate (rETRmax), photoacclimation index (Ek ), photosynthetic efficiency (α), and effective quantum yield (ΔF/Fm' ) in both species. A. coffeaeformis had a greater tolerance to higher temperatures than C. sublittoralis, with nonphotochemical quenching (NPQ) activated at temperatures of 45°C and 50°C. C. sublittoralis, however, demonstrated a more rapid rate of recovery at ambient temperatures. Temperatures between 10°C and 20°C were determined to be optimal for photosynthesis for both species. High temperatures and irradiances caused a greater decrease in ΔF/Fm' values. These results suggest that the effects of temperature are species specific and that short-term exposure to adverse temperature slows the recovery process, which subsequently leads to photoinhibition.

“…Since previous investigations (Raniello et al 2007) have indicated, for congeneric diatoms, the optimal irradiance levels to be between 60 and 140 lM photons AE m )2 AE s )1 , and all our tests were conducted at similar PAR, an influence of light intensity on the productivity of our cultures may be excluded. These low light intensities are in accordance with the results obtained by Parker et al (2007) for Cocconeis sublittoralis and confirm that most Cocconeis species grow preferentially in shaded environments. In addition, this irradiance range has been shown to be suitable for most epibenthic diatoms (Lewis et al 2002, Mouget et al 2005, and Cocconeis spp.…”

“…Finally, the maximum cell density reached in the stationary phase is primarily dependent not only on the species and variety considered (in accordance with Passy 2008), but it is also influenced by the culture medium, with MJ and K promoting the highest densities. This finding may have important implications for future research, as several authors (e.g., Parker et al. 2007) have used f/2 as a standard culture medium for most species of diatoms.…”

“…Therefore, growth curves were obtained for each of two culture conditions (S vs. NS), each species (C1 vs. C2), each of three culture media (f ⁄ 2, K, and MJ), and two neon lamps (Aq vs. GL). Growth rates (GRs) were also calculated for each condition, at each time lag, using the following formula (Parker et al 2007):…”

The optimal conditions for the growth of two conspecific benthic diatoms were defined through factorial experimentation. We investigated the roles of light spectrum, nutrient availability, and culture conditions on the laboratory production of Cocconeis scutellum scutellum Ehrenb. and C. scutellum parva Grunow. Diatoms were cultivated in petri dishes, and inverted optical microscopy was used to periodically record their abundance. Growth curves were constructed from these data for each culture condition. In addition, at the end of the experiment we performed weight measurements to determine the total production for each of the considered conditions. We found that cultivation in nonsealed (NS) petri dishes (permitting gas exchange) represented the most productive technique. Cell density and biomass varied among light spectra, although this effect was inconsistent. For example, the Sylvania Gro-Lux lamp (GL) produced the lowest cell density but highest biomass, suggesting that it may promote the production of larger cells. Surprisingly, of the culture media tested, f/2 (a media commonly used for the culture of diatoms) was the least productive. Diatom density and biomass were variably dependent on the combination of experimental culture conditions and strain used. These physical and chemical factors act mainly on given features of the diatom growth curve. These results permitted us to devise adequate culture protocols, to produce a biotechnologically important substance: a proapoptotic compound that specifically destroys the androgenic gland of a shrimp and could find novel applications in human medicine.
