“…Many carotenoids are being produced by chemical synthesis, which yield products that are pure and cheap (Gordon and Bauernfeind, 1982). Several microorganisms, including fungi, bacteria and algae, are able to produce carotenoids naturally 984 R. Verwaal et al (Johnson and Schroeder, 1996).…”

To obtain insight into the genome-wide transcriptional response of heterologous carotenoid production in Saccharomyces cerevisiae, the transcriptome of two different S. cerevisiae strains overexpressing carotenogenic genes from the yeast Xanthophyllomyces dendrorhous grown in carbon-limited chemostat cultures was analysed. The strains exhibited different absolute carotenoid levels as well as different intermediate profiles. These discrepancies were further sustained by the difference of the transcriptional response exhibited by the two strains. Transcriptome analysis of the strain producing high carotenoid levels resulted in specific induction of genes involved in pleiotropic drug resistance (PDR). These genes encode ABC-type and major facilitator transporters which are reported to be involved in secretion of toxic compounds out of cells. β-Carotene was found to be secreted when sunflower oil was added to the medium of S. cerevisiae cells producing high levels of carotenoids, which was not observed when added to X. dendrorhous cells. Deletion of pdr10, one of the induced ABC transporters, decreased the transformation efficiency of a plasmid containing carotenogenic genes. The few transformants that were obtained had decreased growth rates and lower carotenoid production levels compared to a pdr5 deletion and a reference strain transformed with the same genes. Our results suggest that production of high amounts of carotenoids in S. cerevisiae leads to membrane stress, in which Pdr10 might play an important role, and a cellular response to secrete carotenoids out of the cell.

-Liposomes prepared from a milk fat globule membrane (MFGM) phospholipid fraction have been shown to have significantly different physical and chemical characteristics and appeared to be more stable in a variety of conditions than liposomes prepared from soya phospholipid material. These liposome systems were used to try to encapsulate model hydrophobic (β-carotene) and hydrophilic (potassium chromate) compounds. Liposomes produced from the MFGM-derived phospholipids showed significantly higher entrapment efficiencies for both β-carotene and potassium chromate. The differences were particularly apparent when using the hydrophobic molecules at low ratios of β-carotene to phospholipid. It is likely that the improved incorporation efficiency for β-carotene is due to the partitioning of the molecule between the aqueous phase and the phospholipid membrane, a property which will be dependent on the specific composition of the phospholipid material used. The higher encapsulation efficiency for the potassium chromate appeared to reflect the slightly larger diameter of the liposomes produced from the MFGM material. These results suggest that there may be inherent advantages in the use of liposomes prepared from MFGM-derived phospholipids via microfluidization for the encapsulation of both hydrophobic and hydrophilic compounds.

“…Human and other animals obtain carotenoid from the diet and are unable to synthesize it themselves. Carotenoid are extensively used as color-enhancing additives to animal feed and also applied as food colorants (Gordon et al 1982 ). It is produced by Arthrobacter (Reddy et al 2000 ) and Streptomyces (Dharmaraj et al 2009 ).…”

Microbial-derived products, while do not have many environmental side effects of their synthetic counterparts, have proved more effi cient than those synthetically obtained. The nature has provided a treasure of microorganisms with capabilities to produce vast variety of novel compounds. This ability has been arised during long last of evolution and adaptation to diverse chemical and physical microenviroments. Microbial-derived metabolites have made their own space in industries and therefore human life. Among these microorganisms, halophilic and halotolerant actinobacteria are recently gaining much attentions. Metabolites and biological functions from halophilic or halotolerant members of this phylum of bacteria may resolving the ever-increasing thirst of industry for metabolites with salttolerancy to cope a range of issues from environmental pollution to diseases and world's hunger. In the current chapter, it has been tried to introduce the less dealt group of halophilic and halotolerant actinobacteria, and shed light on their potential to be exploited in various industry sectors.
