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

Interaction Algae–Bacteria Consortia: A New Application of Heavy Metals Bioremediation

“…At present, environmental bioremediation has been used to explore the bacterial consortia role in many different ways. For example, in contaminants such as BTEX (Littlejohns and Daugulis 2008 ), Crude oil (Tang et al 2010 ;RahmanT , P. frederiksbergensis , P. fragi T , P. paucimobilis , P. vesicularis , P. capacia Ambujom 2001 ), Rhodococcus (Ambujom 2001 ), Pedobacter ( P. piscium ), Sphingomonas ( S. paucimobilis Wang et al 2004 ), Stenotrophomonas ( S. rhizophila , S. maltophilia Kim et al 2009 ), Streptomyces (Ambujom 2001 ), and Xanthomonas ( X. maltophilia Wang et al 2004 ), are involved with a high level of effi ciency.…”

Nanopharmaceuticals and Bioremediation

“…Benthic microalgae can remediate organically enriched sediments 84 . Scenedesmus obliquus GH2 (a microalgae) is used to construct an artificial microalgal-bacterial consortium 96 . This isolated microbial consortium upon mixing with asphaltenes fastens and improve oxygen consumption degrading crude oil and asphaltenes 97 .…”

Botryococcus braunii for the production of hydrocarbons and exopolysaccharides and the role of associated bacteria

“…have been shown to be able to degrade polycyclic aromatic hydrocarbons (Tang et al 2010a) and could possibly be degrading the hydrocarbons secreted by B. braunii as its carbon source.…”

“…There are also microbes that may cause detrimental effects on hydrocarbon productivities of B. braunii such as Sphingomonas spp. (OTU 310) with ability to degrade hydrocarbons (Tang et al 2010a). The removal of such detrimental microbes could enhance cultivation allowing more nitrogen available for biomass production and increase hydrocarbon accumulation of B. braunii at larger industrial scale.…”

“…For example, among the various species of bacteria found we identified Sphingomonas spp. that are known to degrade hydrocarbons (Tang et al 2010b). In chapter five with the use of UVC treatment with the EPS producing strain CCALA778, we reduced the bacteria diversity and the abundance to less than 1 % relative abundance.…”
