Potential benefits of Bacillus subtilis-mediated bioflocs in supplementary feeding on triangle sail mussels Hyriopsis cumingii: a pilot study of fluorescence-labeled floc-forming bacteria

open access: yesAquaculture Reports
As micro-particle aggregates, bioflocs may be potential baits for ingestion by triangle sail mussels and supplementary feeding raises more concerns. Besides, a plasmid carrying the green fluorescent protein (GFP) gene was transformed into floc-forming ...

Proteins control in biomineralization processes of the freshwater pearl mussel Hyriopsis cumingii

open access: yes, 2009
Pearls are an amazing example of calcium carbonate biomineralization. They show a classic brick and mortar internal structure in which the predominant inorganic part is composed by aragonite and vaterite tablets. The organic matrix is disposed in concentric layers tightly associated to the mineral structures.
