“…More efficient dialyzers and mass transfer, such as those encountered in a microfluidic platform, would shorten both times. In theory, the device could regenerate just as easily from biological components derived from waste biomass 22 - 24 , or by coupling directly to conventional biosynthesis in a manner similar to natural chloroplast operation 25 - 27 .…”

Photoelectrochemical complexes for solar energy conversion that chemically and autonomously regenerate

Naturally occurring photosynthetic systems use elaborate pathways of self-repair to limit the impact of photo-damage. Herein, we demonstrate a complex that mimics this process consisting of two recombinant proteins, phospholipids and a carbon nanotube. The components self-assemble into a configuration in which an array of lipid bilayers aggregate on the surface of the carbon nanotube, creating a platform for the attachment of light-converting proteins. The system can disassemble upon the addition of a surfactant and reassemble on its removal over an indefinite number of cycles. The assembly is thermodynamically meta-stable and can only transition reversibly if the rate of surfactant removal exceeds about 10−5 sec−1. Only in the assembled state do the complexes exhibit photoelectrochemical activity. We demonstrate a regeneration cycle that uses surfactant to switch between assembled and disassembled states, resulting in increased photo-conversion efficiency of more than 300% over 168 hours and an indefinite extension of the system's lifetime.

“…At this step, the enzymes lycopene synthase, phytoene desaturase and j-carotene add a double bond within the conjugated system to form lycopene; then, carotene cyclases can produce either b-carotene or lutein (via a-carotene) [7].…”

The biosynthesis of the phenolic fraction of olive fruits during ripening and the transformations occurring in this moiety during virgin olive oil (VOO) extraction are discussed in this paper. The influence of agronomical factors that can significantly affect the phenolic profile of VOO is also discussed. Particularly, it is worth emphasizing the role of genetic factors, cultivation and climatic conditions such as water availability, atmospheric temperature, altitude, health status of the fruits, alternate bearing in the olive, and some processing factors such as crushing, malaxation time and temperature or volume of water added during milling. Among these parameters, special attention has been paid to genetic factors due to the high variability observed among Olea europaea genotypes for all recorded traits. In this context, interesting experimental results have been obtained with cultivated and wild olive trees, and also with segregating populations resulting from olive breeding programs. To the authors' knowledge, reviews evaluating the influence of the main factors that contribute to the profile of hydrophilic phenols have not been previously published. The discussion concerning olive breeding programs is a major and novel aspect to be emphasized considering recent trends to obtain new olive cultivars that confer better organoleptic properties and better quality to VOO.

“…This has promoted research into food colorants from natural sources. The less stringent tests necessary for the use of natural colorants and the increase in demand for natural ingredients by the increasingly health conscious have led food manufacturers to relook into the use of natural food colorants [1]. This has also resulted in a proliferation of interest in the development of natural food colorants in recent years.…”

The search for naturally produced substitutes for chemical food colorants has led to a resurgence of interest in pigments synthesized by fungi such as Monascus spp. This fungus has been used in Asia for many centuries as a natural color and flavor ingredient in food and beverages. The red pigments are of particular interest, because red is the most popular food color and true natural pigments suitable for applications in food industries are difficult to obtain. As a result of recent efforts to replace synthetic food dyes with natural colorants, pigments produced by Monascus spp. have attracted worldwide attention. Monascus color, categorized as a natural color, has also been widely used as a food supplement and in traditional medicine. The major objective of this review deals with production of natural microbial color by Monascus spp. and addresses the parameters involved in fungal biofermentation. The fungal strains of Monascus spp. can be either fermented in solid state fermentation (SSF) or in submerged fermentation (SmF). SSF and SmF are two commonly used techniques during various fermentation processes. One important aspect in the development of a biofermentation process is the ability and suitability of the Monascus strain to be employed with a suitable medium.
