SGB’s New Hybrid of Jatropha with Shorter Maturation Period

JatrophaSGB Inc, San Diego, has successfully developed a Jatropha hybrid, which has rapid time of maturity and high yielding capacity. The major barrier, concerned with Jatropha is its long time of maturation of about 5 years. The latest generation hybrids have been reduced to one to two years, which is remarkable.

SGB conducted pre-commercial trials with its top 10 hybrids, and the best performing hybrid being recognised, gave an equivalent of 300 gallons of oil per acre in year one, with a corresponding protein production of 0.6 metric tons which is 30% higher than that of yield from soy. The protein is of high quality and contains essential amino acids, comparable to soybean.

The underlying reason for early failures of Jatropha:
• Insufficient germplasm diversity that obstruct effective breeding and improvement of Jatropha,
• Lack of understanding and/ or implementation of the agronomic practices to unlock full potential of Jatropha

Finally, SGB is done with its necessary trials on this super breed, and is ready to commercialise. An investment of $40 million and 7 years of research has resulted in a viable alternative to soybean and palm as a sustainable source of oil and protein.

Polyols Based on Organosolv Lignin and Fatty Acids

Scientists from University of Strasbourg, France, published results of their recent research on Bio based building blocks for segmented Polyurethanes. A macropolyol was prepared by combining two different biomolecules- lignin and oleic acid, from biomass. NMR and FT-IR analyses are performed to determine the chemical structure of the lignic- fatty acid based polyol. Polyurethanes preolymers are synthesised from 4,4′-methylenebis(phenyl isocyanate) and poly(propylene)glycol of different molecular weights (PPG – 425, 1000 and 2000 g mol−1. ).

On varying the reaction parameters, in the presence of lignin- fattyacid based macropolyol, different PU macromolecular architectures were obtained. The chemical structure of the lignin- based polyurethane was analysed by FT-IR, and the properties of polymers by DSC, TGA, DMTA, and tensile test experiments. Thus obtained new polymers is found to posses advanced properties and may serve as an optimal alternative to conventional polyurethanes. Full Article

Microorganisms for Bio-Based Nylon Intermediates

Genomatic, a U.S. Biotech company, bacteriahas planned to develop technologies for the production of bio-based nylon intermediates- hexamethylenediamine, caprolactam and adipic acid. Approximately, revenue of $18 billion is bagged by these three chemicals every year.

The company has been involved in a several experiments, to study the

production of nylon intermediates by various microorganisms. The research team of Genomatic is basically trying to demonstrate the metabolic pathways, efficient methods of production and recovery of these intermediates. Source

Castor oil based nylon has a relatively low density for a polyamide, good low temperature impact strength and good dimensional stability. Know more on the nylon intermediates from castor oil

Castor Prices Fall Owing to Good Sowing

Delayed monsoon and insufficient rainfall encouraged farmers to shift from other crops to castorseed. Therefore, good sowing in growing regions caused a sharp fall in the price, putting pressure at future trades.

At NCDEX, on 01 September, 2014, Castor prices were down as quoted in the table below.
