Advantageous characteristics of the diatom Chaetoceros gracilis as a sustainable biofuel producer
BACKGROUND Diatoms have attracted interest as biofuel producers. Here, the contents of lipids and photosynthetic pigments were analyzed in a marine centric diatom, Chaetoceros gracilis. This diatom can be genetically engineered using our previously reported transformation technique and has a potential to produce valuable materials photosynthetically. Sustainable culture conditions for cost-effe...
متن کاملEffects of chloramphenicol, erythromycin, and furazolidone on growth of Isochrysis galbana and Chaetoceros gracilis
This study focused on determining the effects of antibiotics on microalgae used as food for scallop larvae. Six different dose levels of chloramphenicol, erythromycin, and furazolidone were added to cultures of Isochrysis galbana and Chaetoceros gracilis. An in vivo experiment was subsequently conducted to determine the effect of chloramphenicol and erythromycin on larval survival of the Pacifi...
متن کاملEffect of bentazon on growth and physiological responses of marine diatom: Chaetoceros gracilis.
The herbicide bentazon (CASRN 25057-89-0) is extensively used in agriculture in Brittany (France) to replace atrazine. Bentazon is not readily adsorbed by soil and therefore it enters adjacent freshwater ecosystems, making its way to estuarine and marine waters areas. Information regarding its effects on marine ecosystems is scarce. Phytotoxicity assessments were conducted in the laboratory on ...
متن کاملEvaluating the Use of Ergosterol as a Bioindicator for Assessing Fungal Response to Water Quality
This study investigated the in situ production of fungal biomass on presterilized woody substrates submerged in natural estuarine and freshwater bodies enriched with nitrogen and phosphoruscontaining chemical compounds. Results suggest that the membrane-bound sterol ergosterol may hold significant promise as an quantitative indicator of fungal response to water quality. We suggest that realisti...
متن کاملProduction of ricinoleic acid-containing monoestolide triacylglycerides in an oleaginous diatom, Chaetoceros gracilis
Ricinoleic acid (RA), a hydroxyl fatty acid, is suitable for medical and industrial uses and is produced in high-oil-accumulating organisms such as castor bean and the ergot fungus Claviceps. We report here the efficient production of RA in a transgenic diatom Chaetoceros gracilis expressing the fatty acid hydroxylase gene (CpFAH) from Claviceps purpurea. In transgenic C. gracilis, RA content i...
