Polyhydroxybutyrate accumulation by a Serratia sp.

Biotechnology Letters, 2007
A strain of Serratia sp. showed intracellular electron-transparent inclusion bodies when incubated in the presence of citrate and glycerol 2-phosphate without nitrogen source following pre-growth under carbon-limitation in continuous culture. About 1.3 mmol citrate were consumed per 450 mg biomass, giving a calculated yield of maximally 55% of stored ...

Organic compatible solutes of halotolerant and halophilic microorganisms [PDF]

, 2014
從苗栗通宵鹽山取得的粗鹽結晶中純化出十八株能生長在4.0 M高鹽的菌株。由16S rDNA序列的分析，確認這十八菌株均為極端高鹽太古生物，其中呈紅色菌落的HLR1~6這六株菌均屬於Haloarcula屬，而十二株淺紅色菌落的HLO1~6及白色菌落的HLW1~6屬於Natrinema屬。這十二株Natrinema屬的菌株均為長桿狀細胞，皆具有觸酶及氧化酶的活性，可以利用色胺酸、檸檬酸和葡萄糖，但都不能分解澱粉、明膠、脂質及卵磷脂，和Natrinema屬的菌株之16S rDNA相似度在97~99 %之間 ...

Polyhydroxybutyrate: An intriguing biopolymer

Bioscience Reports, 1988
The microbial polymer poly-3-hydroxybutyrate (PHB) and related poly-hydroxyalkanoates, such as poly-3-hydroxyvalerate and poly-3-hydroxyoctanoate, are unique biodegradable thermoplastics of considerable commercial importance. The structure, properties and regulation of synthesis and degradation of PHB are reviewed and the microbial production of ...

Polyhydroxybutyrate production by freshwater SAR11 (LD12). [PDF]

ISME J
Abstract SAR11 bacteria (order Pelagibacterales) are oligotrophs and often the most abundant bacterioplankton in aquatic environments. A subset of sequenced SAR11 genomes, predominantly in the brackish and freshwater SAR11 subclades, contain homologs of pha genes, which in other organisms confer the ability to store carbon and energy via
