Abstract:
... The objective of this study was to evaluate three most common scale-up criteria for Haematococcus pluvialis production from cultivation bottles to 2 and 10 L of stirred tank PBRs. Constant volumetric power input (P/V) was found to be the most suitable criterion for H. pluvialis production. Total carotenoid amount per biomass concentration in 2 L and 10 L stirred tank PBRs were determined to be 4.5 ...

Abstract:
... The bio-industrial application of microalgae has gained much attention in recent years. One of the challenges in this field is to lower the cultivation and harvest costs and to achieve the steady productivity. To address this, new systems have been proposed, in which the products are extracted without killing the algal cells. These non-destructive extraction systems are called “milking.” Some of t ...

This review reasons the inevitability of carotenoid for a larger role than just dietary supplements. In an era dominated by chemical or plant-derived carotenoid, bacterial carotenoid provides a compelling forte to be exploited as a promising alternative. Bacteria are amazingly resourceful beings; howeve ...

Abstract:
... BACKGROUND: Carrot (Daucus carota subsp. carota L.) is an important root crop with an available high-quality genome. The carrot genome is thought to have undergone recursive paleo-polyploidization, but the extent, occurrences, and nature of these events are not clearly defined. RESULTS: Using a previously published comparative genomics pipeline, we reanalysed the carrot genome and characterized ge ...

Abstract:
... Nutrients are bio-encapsulated by different structures in plant-based foods, which can behave as digestive barriers upon consumption. These natural barriers can be modified during food processing (e.g. thermal and mechanical treatments). On the one hand, processing can be applied to fully disrupt naturally present barriers, while on the other hand, processing can be used for targeted modifications ...

Abstract:
... Phycobilisomes (PBs) absorb light and supply downstream photosynthetic processes with excitation energy in many cyanobacteria and algae. In response to a sudden increase in light intensity, excess excitation energy is photoprotectively dissipated in PBs by means of the orange carotenoid protein (OCP)-related mechanism or via a light-activated intrinsic decay channel. Recently, we have identified t ...
