Nitro- and amino- substituted aromatic compounds as nitrogen sources for the green alga Scenedesmus obliquus

Biodegradation of aromatic compounds by microalgae

“…Luther and Soeder [19], Luther and Shaaban [20] and Luther [21] were able to confirm that the alga, Scenedesmus obliquus , was able to utilize naphthalene sulfonic acids as a source of sulfur for the production of biomass, releasing the desulfonated carbon ring into the medium. However, desulfonation is dependent on the number (1‐NS>1,5‐NDS>1,3,6‐NTS) and position (1,6‐NDS>2,6‐NDS>2,7‐NDS>1,5‐NDS) of the substituents on the carbon structure [21]. In the case of 1‐naphthalene sulfonate, 1‐naphthol is liberated along with sulfite.…”

Growth and adaptation of the green alga Chlamydomonas reinhardtii on diesel exhaust particle extracts

“…The capacity of algae to degrade petroleum compounds and other arenes has long been known (Walker et al, 1975;Cerniglia et al, 1980;Ellis, 1977), and the use B. Liebe and H. P. Fock of naphthalenesulphonic acids as sulphur sources, or the use of nitro-and amino-substituents of aromatic compounds, has been reported (Luther, 1990). The considerable decrease in concentration of some growth-inhibiting compounds brought about by adapted cells may, therefore, be caused by biodegradation, which would explain both the lag phase and acquired tolerance.…”

Construction of an artificial microalgal-bacterial consortium that efficiently degrades crude oil

“…obliquus was able to utilize naphthalene sulfonic acids as a source of sulfur and nitro and amino substituents from nitrobenzoates and aminonaphthalenes as nitrogen sources for the production of biomass [29,30]. The bacteria then metabolized the products of desulfonation.…”
