Purple bacteria turns sewage into hydrogen energy

Purple bacteria turns sewage into hydrogen energy

November 18, 2018 |

In Spain, researchers at Universidad Rey Juan Carlos found a new method using purple bacteria and electrical currents that reduces carbon emissions from wastewater treatment plants. Purple bacteria are photosynthetic and use infrared light as their energy source, giving them various colors like purple, brown and red. The bacteria can perform metabolic reactions and are […]

Banking on the bacterium bad guy: Sandia tailors E. coli to convert plants into renewable chemicals

Banking on the bacterium bad guy: Sandia tailors E. coli to convert plants into renewable chemicals

May 19, 2018 |

In California, Sandia National Laboratories scientists have demonstrated a new technology based on bioengineered bacteria that could make it economically feasible to produce things like jet fuel, pantyhose, and plastic bottles from renewable plant sources. Economically and efficiently converting tough plant matter, or lignin, has long been a stumbling block for wider use of the […]

Sandia researchers demo bioengineered bacteria to reduce cellulosic biomaterial production costs

May 17, 2018 |

In New Mexico, Sandia Lab asks, what does jet fuel have in common with pantyhose and plastic soda bottles? They’re all products currently derived from petroleum. Sandia National Laboratories scientists have demonstrated a new technology based on bioengineered bacteria that could make it economically feasible to produce all three from renewable plant sources. Piecing together […]

Dutch diesel storage tanks hit hard by bacteria-induced rust from biodiesel and lower sulphur

Dutch diesel storage tanks hit hard by bacteria-induced rust from biodiesel and lower sulphur

February 27, 2018 |

In the Netherlands, the Volkskrant reports that thousands of underground diesel storage tanks will probably have to be emptied and replaced over the coming years due to corrosion from bacteria growing in biodiesel and by lower sulphur content that failed to check the bacteria growth. Last year, storage tanks were already found to be leaking […]

Stanford scientists find new type of cellulose in bacteria

Stanford scientists find new type of cellulose in bacteria

January 22, 2018 |

In California, Stanford scientists have found a new type of cellulose in bacteria with properties that could make it an improvement over traditional cellulose for fuels and other materials, or for better understanding and treating bacterial infections. They describe this modified cellulose, called pEtN, and its possible applications in the Jan. 18 issue of Science. […]

Saudi researchers determine giant fish gut bacteria help to digest algae

October 12, 2017 |

In Saudi Arabia, Red Sea surgeonfish use metabolically diverse giant bacteria to digest different types of algae, according to new research. Not only do these findings explain the basis of surgeonfish diversity, but they may also provide a valuable genetic resource for biofuel research. An international team led by King Abdullah University of Science & […]

University of California, Irvine researchers using bacteria to produce hydrocarbons from industrial waste

University of California, Irvine researchers using bacteria to produce hydrocarbons from industrial waste

August 30, 2017 |

In California, researchers at the University of California, Irvine envision growing the Actinobacter vinelandii bacteria on industrial carbon waste to generate hydrocarbons. They found that the A. vinelandii strain that expresses the nitrogenase enzyme can produce methane (CH4), ethylene (C2H4), ethane (C2H6), propylene (C3H6), propane (C3H8) and butane (C4H10). So far they have optimized the […]

KU Leuven researchers find bacteria DNA mutates under stress

KU Leuven researchers find bacteria DNA mutates under stress

May 9, 2017 |

In Belgium, bacteria need mutations or changes in their DNA code to survive under difficult circumstances. When necessary, they can even mutate at different speeds. This is shown in a recent study by the Centre of Microbial and Plant Genetics at KU Leuven. The findings open up various new avenues for research, ranging from more efficient […]
