Abstract Phytoplankton blooms provoke bacterioplankton blooms, from which bacterial biomass (necromass) is released via increased zooplankton grazing and viral lysis. While consumption of algal during well-studied, little known about the concurrent recycling these substantial amounts necromass. We demonstrate that biomass, such as alpha-glucan storage polysaccharides, generated organic matter, reused thus itself a major carbon source in vitro diatom-dominated bloom. highlight conserved...
Abstract Comparative analyses determined the relationship between structure of bisphenol A (BPA) as well seven analogues (bisphenol B (BPB), C (BPC), E (BPE), F (BPF), Z (BPZ), AP (BPAP), PH (BPPH)) and their biotransformability by biphenyl-degrading bacterium Cupriavidus basilensis SBUG 290 . All bisphenols were substrates for bacterial transformation with conversion rates ranging from 6 to 98% within 216 h 36 different metabolites characterized. Transformation biphenyl-grown cells...
Abstract The polysaccharide β-mannan, which is common in terrestrial plants but unknown microalgae, was recently detected during diatom blooms. We identified a β-mannan utilization locus (PUL) the genome of marine flavobacterium Muricauda sp. MAR_2010_75. Proteomics showed induced translation 22 proteins encoded within PUL. Biochemical and structural analyses deduced enzymatic cascade for utilization. A conserved GH26 β-mannanase with endo-activity depolymerized β-mannan. Consistent...
Outer membrane extensions are common in many marine bacteria. However, the function of these surface enlargements or extracellular compartments is poorly understood. Using a combined approach microscopy and subproteome analyses, we therefore examined Pseudoalteromonas distincta ANT/505, an Antarctic polysaccharide degrading gamma-proteobacterium. P. produced outer vesicles (MV) vesicle chains (VC) on non-polysaccharide carbon sources during exponential stationary growth phase. Surface...
Abstract Laminarin, a β(1,3)‐glucan, serves as storage polysaccharide in marine microalgae such diatoms. Its abundance, water solubility and simple structure make it an appealing substrate for bacteria. Consequently, many bacteria have evolved strategies to scavenge decompose laminarin, employing carbohydrate‐binding modules (CBMs) crucial components. In this study, we characterized two previously unassigned domains laminarin‐binding CBMs multimodular proteins from the bacterium...
Marine algae are responsible for half of the global primary production, converting carbon dioxide into organic compounds like carbohydrates. Particularly in eutrophic waters, they can grow massive algal blooms. This polysaccharide rich biomass represents a cheap and abundant renewable source. In nature, diverse group polysaccharides is decomposed by highly specialized microbial catabolic systems. We elucidated complete degradation pathway green algae-specific ulvan previous studies using...

Abstract The ß-(1,3)-glucan laminarin functions as storage polysaccharide in marine stramenophiles such diatoms. Laminarin is abundant, water-soluble and structured simply, making it an attractive substrate for bacteria. As a consequence, many bacteria have developed competitive strategies to scavenge decompose laminarin, which involves carbohydrate-binding modules (CBMs) key players. We therefore functionally structurally characterized two yet unassigned domains laminarin-binding CBMs...
