Bioconversion of eugenol into food flavouring agent vanillin Nature Precedings
Suaib Luqman; Sudeep Tandon; Alok Somvanshi; Suchita Srivastava; Mahendra P. Darokar; Suman P. S. Khanuja.
Microorganisms have the ability to chemically modify a wide variety of organic compounds by a process referred to as biological or microbial transformation, or in general, bioconversion. The microbial cells and their catalytic machinery (enzymes) accept a wide array of complex molecules as substrates, yielding products with unparallel chiral (enantio-), positional (region-) and chemical (chemo-) selectivity through various biochemical reactions. The present study was formulated on the objective of the conversion of abundantly available phytomolecules eugenol into vanillin, a compound of industrial importance, using microorganisms Aspergillus flavus, Aspergillus niger and Pseudomonas aeruginosa. These microbes were found to be capable of converting eugenol...

Biodegradable Luminescent Silicon Quantum Dots for Two Photon Imaging Applications Nature Precedings
Chen-An Tien; Folarin Erogbogbo; Ching-Wen Chang; Priscilla Adjei-Baffour; Wing-Chueng Law; Mark T. Swihart.
Cadmium- and lead-based quantum dots are normally coated for biological applications, because their degradation may result in the release of toxic heavy metal ions. Here, we synthesize silicon quantum dots that are expected to biodegrade to non-toxic products. A chitosan coating is used to render the silicon quantum dots stable in storage conditions and biodegradable at physiological conditions. The applications of these particles are demonstrated in cellular imaging with single and two-photon excitation. These results open the door for a new generation of silicon quantum dots that may have a wide variety of applications derived from the flexibility of chitosan.

Biological Limits on Agricultural Intensification: An Example from Resistance Management AgEcon
Laxminarayan, Ramanan; Simpson, R. David.
When the application of pesticides places selective evolutionary pressure on pest populations, it can be useful to plant refuge areas-crop areas intended to encourage the breeding of pests that are susceptible to the pesticide. Renewed interest in refuge areas has arisen with recent advances in biotechnology and genetically modified (GM) crops. In this paper, we use a simple model of the evolution of pest resistance to characterize the socially optimal refuge strategy for managing pest resistance. We demonstrate some interesting analogies with other models of renewable resource management, such as those of fisheries. Among the analogous results are findings that maintaining what we might call "maximal sustainable susceptibility" is typically not...

Biological robotics and nanorobotred cells: Characterization and applications Nature Precedings
Rakesh Sharma; Soonjo Kwon; Ching J. Chen.
In human body, nanorobot-like red blood cells get exposed to human body fluids and many physico-chemical changes inside while these nanorobots (fullerene structure coated hemoglobin embedded iron inorganic elements) remain safe and perform killer action against bacteria or virus. We propose this killer action as ‘nanorobot driven nanomedical treatment’ to combat a bacterial or viral infection. The red cells also act as imaging agent due to oxygen binding character. Our experiments were focused on the application of nanorobot (red cells) to make them immune resistant against viruses and making them as useful contrast agents in magnetic resonance imaging use based on their behavior in nanomagnetic fields. It consists of an injection of...

Jozala,Angela Faustino; Geraldes,Danilo Costa; Tundisi,Louise Lacalendola; Feitosa,Valker de Araújo; Breyer,Carlos Alexandre; Cardoso,Samuel Leite; Mazzola,Priscila Gava; Oliveira-Nascimento,Laura de; Rangel-Yagui,Carlota de Oliveira; Magalhães,Pérola de Oliveira; Oliveira,Marcos Antonio de; Pessoa Jr,Adalberto.
ABSTRACT The use of biopharmaceuticals dates from the 19th century and within 5-10 years, up to 50% of all drugs in development will be biopharmaceuticals. In the 1980s, the biopharmaceutical industry experienced a significant growth in the production and approval of recombinant proteins such as interferons (IFN α, β, and γ) and growth hormones. The production of biopharmaceuticals, known as bioprocess, involves a wide range of techniques. In this review, we discuss the technology involved in the bioprocess and describe the available strategies and main advances in microbial fermentation and purification process to obtain biopharmaceuticals.

Bio-resources for sharing: which communities and what specific needs Nature Precedings
Andres Metspalu.
Biobanks are an important source to obtain samples and data for research purposes for a wide array of communities. In fact, sharing of bio-resources and data is an integral part of a biobank's role. For an effective partnership a list of requirements or needs have to be met, assuring quality of the resources shared as well as quality of the collaboration in general. Tracking and documenting bio-resource sharing and collaborations of a biobank can be seen as one indicator of the "impact" a biobank has to the field. As an example, the practice of the Estonian Genome Center of the University of Tartu is presented.

Biossegurança ambiental de OGMs. Infoteca-e
ANDRADE, S. R. M. de.
ABSTRACT: In 2005, there were 90 million hectares cultivated with GMOs by 8.5 million producers in 21 countries. In 2006, we commemorated 10 years of commercial production of GMOs. Currently there are 10 million farmers planting 100 million hectares. However, several points were raised concerning the environmental impact of GMOs: (1) risk of cultivated or wild hybrid become a harmful invasive species, (2) development of resistance by the massive use of technology, (3) possibility of vertical or horizontal gene flow, (4) adverse effect on non-target and beneficial species, (5) impacts on crop production systems. This article discusses the main results on those concerns. The data obtained so far show that the environmental impacts of GMOs ares similar to a...

Biossegurança de alimentos transgênicos. Infoteca-e
ANDRADE, S. R. M. de.
ABSTRACT: The use of transgenic plants on the human diet is a matter of great concern for the scientific community and the public in general. However, it is important to consider that before the release for human consumption, transgenic foods are submitted to an extensive series of rigorous tests. These tests includes the characterization of the expressed protein, in vitro digestibility and oral evaluation of acute toxicity in mice, studies of the structural homology of the protein with other known toxic proteins, allergenic potential and nutritional equivalence. Questions about the true risks of transgenic food for human health cannot be answered in general terms, but we can expect a lower potential risk when compared to another type of food that did not...

Biotechnology and the Development of Food Markets: Retrospect and Prospects AgEcon
Moschini, GianCarlo.
Biotechnology has had an important impact on the agricultural and food industries over the last twelve years by way of fast and extensive adoption of a few genetically modified (GM) crops. This has produced large efficiency gains, including higher yields and reduced costs of weed and pest control, as well as some environmental benefits. The expected development of crops with additional agronomic traits, and with output traits to improve the nutrition and health attributes of food products, holds the potential for even more pervasive impacts. Full realisation of such promises may require overcoming the constraining effects of restrictive GM product regulations.

Biotechnology applied to salmoniculture R. Bras. Zootec.
Isler,Iván Valdebenito.
This work presents a conceptual analysis of the main biotechnologies used in Chilean salmoniculture, which is based on the production of Atlantic salmon (Salmo salar, 356.407 t),silver salmon or coho (Oncorhynchus kisutch, 116.481 t), (O. tshawytscha, 2.062 t) and rainbow trout (O. mykiss, 189.178 t).These activities are focused on the photoperiod artificial manipulation to obtain out-of-season spawning, in the use of hormonal therapies which allow synchronizing the final oocyte maturation (FOM) and sexual maturity acceleration or the increase in milt volume produced by males. Such actions are carried out using GnRHa in doses close to 10 µg/kg of fish. Once sexual maturity is reached, in vitro manipulation of gamets must often be done due to either the...

BIOTECHNOLOGY IN AGRICULTURE: IMPLICATIONS FOR FARM-LEVEL RISK MANAGEMENT AgEcon
Makki, Shiva S.; Somwaru, Agapi; Harwood, Joy L..
This study examines the risks associated with adoption of biotech crops and discusses their implications for risk management at the farm level. We develop an analytical risk evaluation matrix framework to illustrate changes in production and marketing risks of biotech and non-biotech crops. Price uncertainty generated by consumer concerns is the major risk facing biotech farmers, while cross-pollination with biotech crops and preservation of non-biotech status are major concerns for non-biotech farmers. Improved market infrastructure to handle biotech products and modification of the current risk management tools to accommodate new risks are essential in reducing the farm-level risks.
