Biofuels: Improved Algae Biomass Yield


I have filed a US Provisional Patent for on a new photobioreactor system that improves biomass yield of aquatic microalgae. Currently I am working on the regular patent (PCT) application. Looking for investors/ licensees for countries other than India.

Full Description

A method to grow a synchronized short cell cycle aquatic microalgae using a large volume bioreactors and solar trackers to substantially improve biomass yield.

Prominent features:

-          Large volume vertical bioreactors that provide alternate dark and light regimens for an algae colony.

-          Each bioreactor represents a complete cell cycle.

-          Improved surface to volume ratio to improve light exposure.

-          Solar trackers track sunlight to bioreactors to overcome mutual shading of bioreactors.

-          Night time artificial lighting for round-the-clock photosynthesis.

-          Short cell cycle algae complete multiple cell divisions per day. The colony synchronized to improve yield.

-          Media temperature manipulated in relation to incident light to achieve exponential growth.

-          Increased control on growth environment to overcome adverse climatic conditions.

-          Improved Carbon dioxide utilization. Respiratory carbon dioxide recycled to reduce system footprint.

-          Gravitational media transport to reduce energy input.

-          Improved water management- evaporative water recycled.

-          Dissolved gases better managed. Photosynthetic oxygen can be recovered for commercial use.

-          Better control on nutrients and pH

-          Successfully addresses downward settlement of cells and adherence to bioreactor walls;  Fouling and culture collapse; Photo-inhibition; and predators. contamination & pathogens.

-          The system is highly scalable and replicable.
