TL;DR: Although excellent progress has been made in recombinant hosts, the barriers to obtaining high quantities of PHA at low cost still remain to be solved, and the commercially viable production of P HA in crops appears to be a realistic goal for the future.

TL;DR: The microvalve/micropump/micromixers allow high levels of PCR chip integration and analytical throughput and the advances of microvalves, micropumps, and micromixer within PCR microfluidic chips over the past ten years are surveyed.

TL;DR: In this review, the vast arrays of reactions that cause scission of hyaluronan polymers is presented, including those on an enzymatic, free radical, and chemical basis.

TL;DR: More work is needed in areas such as increasing specific desulfurization activity, hydrocarbon phase tolerance, sulfur removal at higher temperature, and isolating new strains for Desulfurizing a broader range of sulfur compounds.

TL;DR: Biosorption has emerged as a low-cost and often low-tech option for removal or recovery of base metals from aqueous wastes, and recent research regarding the biosorption of some precious metals is reviewed here.

TL;DR: The methods of cofactor retention for development of sustainable and regenerative biocatalysts as revealed in these recent studies are reviewed with the intent to complement other reviewing articles that are mostly regeneration chemistry-oriented.

TL;DR: Development of novel transgenic plants for efficient phytoremediation of xenobiotic pollutants, field testing and commercialization will soon become a reality.

TL;DR: In this article, a review examines the research on S. cerevisiae strains that have been genetically modified or adapted to ferment xylose to ethanol, identifying the current state of these efforts and areas where further research is required.

TL;DR: A review of the current status of laccase production by wild-type strains of filamentous fungi at the bioreactor scale is presented in this paper, where the authors discuss the main drawbacks of using laccases in a wide variety of processes, such as textile dye decolouration, pulp bleaching, effluent detoxification, biosensors and bioremediation.

TL;DR: In insects, choice of cell line, growth conditions and use of the baculovirus expression system opens up possibilities to engineer the nutritional value of the biomass, and also insect cells may be a promising novel source of protein.

TL;DR: Production and processing of dinoflagellates to extract bioactives, require attention to biosafety considerations, and a lack of sufficient quantities of toxins for investigational purposes remains a significant limitation.

TL;DR: The nature of such parameters (eg solvent nature, water activity, chemical modification of substrates) and their effect are discussed and examples of lipase-catalyzed lipophilization reactions of various sugar, amino acids or phenolic derivatives are illustrated.

TL;DR: Two-phase partitioning bioreactors allow the biological removal of volatile organic compounds from contaminated gas streams at unprecedented rates and concentrations but have hitherto been designed as laboratory-scale well-mixed stirred-tank reactors or as biofilters that contain a non-aqueous phase.

TL;DR: Several approaches aimed at optimizing protein secretion in Bacillus subtilis are discussed, according to the available knowledge of secretion machinery.

TL;DR: The purpose of this review is to focus upon contemporary information on biotechnological advances made in mango and describes some ways of overcoming the problems encountered during in vitro propagation of mango.

TL;DR: Hydrolysis of the whey protein alpha-lactalbumin with a specific serine protease has been shown to result in regular nanotubes of approximately 20 nm in outer diameter and reaching several mum in length.

TL;DR: This review focuses on effects of pressure, temperature and the properties of the SCFs, on enzymatic reactions, including phase behavior, reaction rate and activation volume in SCFs.

TL;DR: A review of the potential of VHb application in biotechnology industry can be found in this article, where many well-studies areas are presented to illustrate the potential for VHB application.

TL;DR: The development history of packed-bed bioreactors used for the culture of mammalian cells is described and the current applications of PBRs are reviewed and the steps forward in the development of these systems for bioprocess and biomedical applications are discussed.

TL;DR: Factors involved in product handling, such as storage temperature, light exposure, and shaking, have been implicated in immunogenicity, while container closure systems are no less important.

TL;DR: Examples are discussed whereby immunogenicity associated with some of these changes can occur, leading to decreased biological activity, alteration of molecular structure, and possible increased risk of host immune responses following administration.

TL;DR: Oleosins stabilize oil bodies in seeds and other tissues and contain a unique hydrophobic domain which appears to be inserted into the oil matrix as an alpha-helical hairpin.

TL;DR: Several strategies have been explored to obtain high-affinity recombinant antibodies from antibody libraries: biopanning optimization can be performed through elution with free hapten, analogue pre-incubation and subtractive panning, and mutagenesis techniques have been used with various degrees of success to affinity mature or modify haptens-specific antibodies.

TL;DR: Among the food globular proteins, whey proteins and soy proteins are the most extensively studied for their ability to form different textures upon proteolysis.
