When present on the band surface " Beggiatoa " appears white due to intracellular inclusions of stored elemental sulfur.
2.
These age onset degenerative diseases are associated with the aggregation of misfolded proteins into insoluble, extracellular aggregates and / or intracellular inclusions including cross-beta sheet amyloid fibrils.
3.
Some species can form intracellular inclusions of polyhydroxyalkanoates under certain adverse environmental conditions, as in a lack of elements such as phosphorus, nitrogen, or oxygen combined with an excessive supply of carbon sources.
4.
Bacteria of the genus " Acinetobacter " are known to form intracellular inclusions of polyhydroxyalkanoates under certain environmental conditions ( e . g . lack of elements such as phosphorus, nitrogen, or oxygen combined with an excessive supply of carbon sources ).
5.
Bacteria of the genus " Azomonas " are known to form intracellular inclusions of polyhydroxyalkanoates under certain environmental conditions ( e . g . lack of elements such as phosphorus, nitrogen, or oxygen combined with an excessive supply of carbon sources ).
6.
Bacteria of the genus " Azotobacter " are also known to form intracellular inclusions of polyhydroxyalkanoates under certain environmental conditions ( e . g . lack of elements such as phosphorus, nitrogen, or oxygen combined with an excessive supply of carbon sources ).
7.
Once the population has reached a substantial level, the nutrient composition is changed to force the micro-organism to synthesize PHA . The yield of PHA obtained from the intracellular inclusions can be as high as 80 % of the organism's dry weight.
