In vitro and in vivo investigation of the antibacterial, antivirulence, and antiquorum sensing activities of β-carotene against difficult-to-treat resistant Pseudomonas aeruginosa [PDF]

BMC Microbiology
Background Difficult-to-treat resistant (DTR) Pseudomonas aeruginosa has strong drug resistance and can tolerate a diversity of antibiotics. Infections triggered by DTR P. aeruginosa urgently require research and development of innovative antibiotics.

Isolation of β-caroten from Brown Tiger Shrimp shell waste (Penaeus esculentus) and its antioxidant activity using ABTS (2,2-azinobis- [3-ethylbenzothiazoline-6-sulfonicacid] method [PDF]

Sains Natural: Journal of Biology and Chemistry, 2021
BrownTiger Shrimp (Penaeus esculentus) is a fishery export commodity that has high potential and categorize major commercial value.The waste in the form of shell produced from the shrimp industry has not been used properly and efficiently. In fact, most of it is waste that also pollutes the environment.Shrimp shell contained a lot of carotenoid ...

The γ-actin encoding gene from the β-carotene producerBlakeslea trispora [PDF]

FEMS Microbiology Letters, 2005
We determined the nucleotide sequence of a 4599-bp DNA genomic fragment including the γ-actin encoding gene from Blakeslea trispora, showing an open reading frame of 1561 bp interrupted by four introns with fungal consensus splice-site junctions. The untranslated regions of the actA gene contain a consensus TATA box, a CCAAT motif, a large pyrimidine ...

Isolation of a carotenoid biosynthesis gene coding for ζ-carotene desaturase fromAnabaenaPCC 7120 by heterologous complementation [PDF]

FEMS Microbiology Letters, 1993
A screening procedure for carotenoid genes involving heterologous complementation with two different plasmid constructs was developed. The plasmids contained the crtE and crtB genes from Erwinia unredovora together with the phytoene desaturase gene from either Rhodobacter capsulatus or Synechococcus PCC 7942. Transformation in E.

ROS Induce β-Carotene Biosynthesis Caused by Changes of Photosynthesis Efficiency and Energy Metabolism in Dunaliella salina Under Stress Conditions

Frontiers in Bioengineering and Biotechnology, 2021
The unicellular alga Dunaliella salina is regarded as a promising cell factory for the commercial production of β-carotene due to its high yield of carotenoids. However, the underlying mechanism of β-carotene accumulation is still unclear. In this study,

Selection of Indonesia Cassava (Manihot esculenta Crantz) Genotype as Source of β-Carotene

Biodiversitas Journal of Biological Diversity, 2008
Fourteen genotypes of Indonesia cassava (Manihot esculenta Crantz) of two generations were evaluated for β-carotene content. The β-carotene content of tubers and leaves were determined by spectrophotometry method. Other parameterssuch as water and ash contents were also evaluated. Results showed that β-carotene content of tubers of fourth generation(

Functional analysis of γ-carotene ketolase involved in the carotenoid biosynthesis ofDeinococcus radiodurans [PDF]

FEMS Microbiology Letters, 2009
Deinococcus radiodurans strain R1 synthesizes a unique ketocarotenoid product named deinoxanthin. The detailed steps involved in the biosynthesis of deinoxanthin remain unresolved. A carotene ketolase homologue encoded by dr0093 was inactivated by gene mutation to verify its function in the native host D. radiodurans. Analysis of the carotenoids in the
