Nov 1, 2020 · Purple phototrophic bacteria (PPB) are receiving increasing attention due to their capability of growing photoheterotrophically under anaerobic conditions.

Dec 13, 2018 · The organic compounds and nutrients present in sewage are carbon sources that could be used to make biofuels. And a team of researchers in Spain has found an efficient way to do that with the help of a light-absorbing purple bacteria.

Nov 20, 2024 · Clostridium thermocellum bacteria (gray/white) are deconstructing plant material (purple) in this image. The microbes digest and ferment plants simultaneously in a consolidated processing method to produce ethanol as a biofuel blendstock to power planes, ships and big rigs.

Jan 1, 2025 · Purple acid phosphatase (PAP, EC 3.1.3.2), a metalloenzyme known for hydrolyzing various organophosphate esters to release inorganic phosphate for cellular metabolism (Bhadouria and Giri, 2022), has been identified as a promising candidate.

Jun 18, 2021 · Energy crisis and global climate change have driven an increased effort toward biofuel synthesis from renewable feedstocks. Herein, purple nonsulfur photosynthetic bacterium (PNSB) of Rhodobacter capsulatus was explored as a platform for high-titer production of a terpene-based advanced biofu …

Mar 9, 2025 · Wastewater treatment with purple nonsulfur bacteria (PNSB) is an emerging biotechnology for sustainable wastewater management and resource recovery.

Apr 19, 2017 · Photofermentation is carried out by purple non sulfur bacteria (PNSB), that are anoxygenic phototrophic bacteria, converting substrates to hydrogen, carbon dioxide, and microbial biomass (Heiniger et al. 2012; Adessi and De Philippis 2014; Hallenbeck and Liu 2016).

biofuel production as bioethanol, which represent a downcycling of this valuable by-product. Molasses is primarily composed of sucrose, but its composition varies significantly depending on the raw material and the processing method (Palmonari et al., 2020). The sugar fraction in sugarcane and sugar beet molasses reach up to around 70.0% of the

Dec 12, 2018 · Cue purple phototrophic bacteria. They capture energy from sunlight using a variety of pigments, which turn them shades of orange, red or brown – as well as purple. But it is the versatility of their metabolism, not their color, which makes them so interesting to scientists.
