Dynamin probably pinches off the membranes at the bridge between the daughter plastids by a biochemical reaction between the PH domain and the double membrane. After mitochondrial division, the remnants of the mt-division machinery then adhere to one side of the daughter mitochondria and the dynamin ring is broken into small patches.
The autophagosome, a special vesicle with a double membrane structure, is an important marker of autophagy activation, which ultimately fuse with the lysosome to form the autolysosome, leading to the degradation of cellular structures [18].
In order to decouple the main membrane from the underlying substrate a double membrane system was used: first, a supported membrane of uniform composition was deposited on the substrate.
During macroautophagy cytoplasmic contents are sequestered in double membrane bound vesicles called autophagosomes and delivered to lysosomes for degradation [4, 5].
abortus S19 and Brucella abortus S19[DELTA]per were negatively stained with 0.5% uranyl acetate revealed the presence of multiple intact spherical vesicles with electron dense centre surrounded by a double membrane, though conventionally released few single membrane enclosed vesicles were also viewed.
Continual inspections were carried out to ensure that no evidence of water ingress was detected within the basement structure, which is protected by a sophisticated re-injectable double membrane waterproof system.
In recent years, the Group's subsidiary, Fong's Water Technology, has developed the wastewater treatment technology, to achieve the full biochemical no sludge dyeing sewage treatment and high efficiency water recycling system with double membrane technology applications, providing one-stop sustainable solutions of dyeing wastewater treatment especially for the dyeing and finishing industries.
Autophagy involves die engulfment of cellular organelles into specialized vacuoles surrounded by a double membrane. The contents of these vacuoles arc delivered to the lysosome, another organelle within the cell, where they are degraded to useful small molecules and help to generate energy and biomass for the synthesis of macromolecules and new organelles.

This group of bacteria is classified as 'gram-negative' because their cells have a double membrane or outer layer, whereas gram-positive bacteria have only one outer layer.
