2 Markets Food: billion-$ market Fodder: billion-$ market Fuels: billion-$ market Eco: billion-$ market

3 One Product Fits All Food: billion-$ market Fodder: billion-$ market Fuels: billion-$ market Eco: billion-$ market Transgenic Plants

4 Our Technology Food: billion-$ market Fodder: billion-$ market Fuels: billion-$ market Eco: billion-$ market «FURLAC» DE 102007053992.6 PCT/EP20008/009596 «HIMBEER» DE102008038937.4 «YOGI» DE102008064223.1. Spin-offs huge market Transgenic Plants

5 Problems To Be Solved The global energy supply is critical. – Fossil fuel reserves (coal, oil, gas) are limited. – Regenerative energies are not sufficiently available. – Nuclear energy is politically unacceptable. Biofuels present a viable alternative only if they do not endanger food production. – Without fuel mechanized agriculture is impossible. Arable land is decreasing in quantity and quality. – Malnutrition and starvation still affect millions. – Excessive agriculture worsens things. Fresh water is increasingly scarce. The world population is still growing. – Industrialization also increases per capita demands.

6 ...that can provide both food/fodder and biofuel to satisfy the growing demands of a growing population,...that does not require arable land to grow and hence does not interfere with conventional agriculture,...that can be used for «ecorestoration» in the widest sense, including soil amelioration,...that is tolerant to salt water and thus does not increase fresh water consumption,...that ideally withstands a wide variety of environ- mental conditions. Thus we need something...

7 The Markets (1) Food and fodder in the context of our patents: Any plants may be used Suitable for direct human consumption Suitable also for feeding cattle Increased growth without need for fertilizer Do not exhaust the soil; with suitable plants such as duckweed or algae, no arable land is required at all Salt resistance and stress tolerance Thus, they can be used to achieve a sustainable increase in global agricultural productivity The global population could be fed effectively using the plans presented here Huge net profits from licensing fees for a globally used product

8 The Markets (2) Biofuel in the context of our patents: Significantly higher productivity than conventional biofuel plants No competition with food and fodder production: Hitherto unused areas can be used With a suitable choice of plants such as the alga Hæmatococcus which is naturally rich in hydrocarbons (carotenes), refined fuels can be obtained more cheaply Global energy demands could be satisfied using the plans presented here Huge net profits from licensing fees for a globally used product

9 The Markets (3) «Eco»: A wide variety of environment-related applications are envisioned, including: CO 2 sequestration to combat climate change; emission minimization in power plants Clearing of low-MW silicate from waste waters and synthesis of phyllosilicates to improve soils Occupation of natural habitats to control pest organims and their vectors (e. g. covering open water to suppress malaria mosquitoes) Removal of oil and petrol contaminations from soil and water Huge net profits from licensing fees for several globally used products

10 The Markets (4) Other applications: Please see the PCT/EP2008/009596 for details on what kind of possible applications has been claimed so far Minor possible applications claimed therein include: – Production of paper and cardboard – Expression of pharmaceutically valuable proteins – Production of sugars, «bioplastics» etc. – Pest control Still further applications may be developed

11 Investment Safety The project comprises a plurality of new techno- logies («Furlac», «Himbeer», «Yogi», etc.). Each new technology can be put to a variety of uses (see «Spin-Offs and By-Products»). Most uses (e. g. food, energy) are of global importance and unlikely to be obviated by unforeseeable changes or advances. Even if some technologies and/or applications should fail to deliver their promises, there are still plenty of market opportunities to make the project an economic success.

12 Knight Moves Soil amelioration Waste water treatment Pest control FuelFood and fodder CO 2 sequestration Removal of oil slicks Paper, sugar, bioplastics

13 Core Project: «Furlac» Improve plant growth rates – – Increase utilization of sunlight Make plants independent of fertilizer – – Enable plants to use atmospheric nitrogen Render plants resistant to salt water – – Pump salt out of the cells Environment safety feature: Limit maximum growth – – Built-in senescence

14 Core Project: «Furlac» Improve plant growth rates – Increase utilization of sunlight Make plants independent of fertilizer – Enable plants to use atmospheric nitrogen Render plants resistant to salt water – Pump salt out of the cells Safety feature: Limit maximum growth – Built-in senescence Requirement for working effectively

15 Increasing Sunlight Utilization (1) plants use only 4% of incoming sunlight only red and blue light is absorbed in the chloroplasts, green light is reflected FRET (Foerster Resonance Energy Transfer): this physical effect allows fluorescent substances to directly transmit energy to one another a fluorescent substance in the chloroplasts absorbing green light could utilize the rich green fraction of sunlight by transmitting it to the chlorophyll

16 Increasing Sunlight Utilization (2) Nobel Prize 1999 (Blobel): How to place proteins at subcellular locations – Any protein can now be placed in the chloroplasts Nobel Prize 2008 (Chalfie): Fluorescent proteins – several proteins absorb green to yellow light and can transfer it to chlorophyll Taken together, these two discoveries basically solve the problem Subtleties covered by «YOGI technology»

17 Fertilizer Independence Enzymes utilizing atmospheric nitrogen are known, but they need lots of energy and are sensitive to oxygen This energy plus is provided by increased sun- light utilization The enzymes are «blobeled» to places in the cell where oxygen is scarce (mitochondria) Subtleties also covered by «YOGI technology»

18 Compatibility with salt water Enzymes pumping salt out of the cells are known (e. g. from the human kidney), but they need lots of energy. More energy is provided by increased sunlight utilization.

19 Built-in Senescence In the absence of the enzyme telomerase, cell growth is limited, and cells become senescent. Place therefore the cells' intrinsic telomerase under external control (e. g. with Bujard's TET system), and you get a double advantage: – No danger of biosphere overgrowth by the trans genic plants – (farmers) cannot illegally propagate the plants

20 What To Do? Part A: Construct chloroplast fluorescence gene in the chloroplast and place it in plant cell energy Part B: Construct mitochondrial nitrogenase gene and place it in plant cell nitrogen Part C: Provide salt pump gene and place it in plant cell! compatibility with salt water Part D: Replace the plant's telomerase with regulated telomerase ! safety – Not required for proof-of-principle stage!

21 Units of the Project (I) – Core project: – comprises parts A, B, C and D – «YOGI technology» may be required (II) – Add-ons: – comprises parts E, F and G – «YOGI technology» mandatory (III) – Spin-offs and by-products: – interesting individual applications – further «extras» to be determined after consult- ation with sponsors and interested 3 rd parties

22 Plants of Interest We develop our processes by using unicellular, microscopic model organisms which are nevertheless already useful in their own right: – Chlorella – Hæmatococcus After proof-of-principle, the results are transferred to duckweed or to any other plant of interest (including maize,rapeseed, soybean, etc.)

23 Dimensions of the Work (1) Each of the four parts is roughly comparable to a master's thesis. – If it works, it works. No scale-up problems in biology. – In the best case, each part could be done in a month. Each of the four parts is basically simple but there may be sticky spots. – We have anticipated this by designing the powerful «YOGI technology». – However, its implementation will require work and expenses. – Rather allow for more conservative timelines. – 10 months for each of A, B and C + 4 months initial setup – Proof–of–principle for A + B after 24 months

24 Dimensions of the Work (2) Apart from our research work, in work with biological systems there is generally seen very much routine labor: – 60 – 70% of all work can be done by technicians: – Maintenance of cell cultures and plants – Production of buffers, media and other «commodities» – Verification of lab equipment – 10 – 20% can be done by unskilled lab workers – Cleaning glassware and other equipment – Disposing of waste material – Other chores Sufficient staffing is indispensable: – for core project: at least + 3 technicians + 1 worker – preferably: + 6 technicians + 2 workers, however, – the more, the better! (Swifter development saves time, resulting in better return-on-investment.)

25 Dimensions of the Work (3) Our Patents: – «Furlac» (PCT/EP2008/009596) – enters the national / regional phase in summer 2010: – translations – dissolves into a bunch of national/regional applications – all PCT countries should be considered – «Yogi» (DE 10 2008 062 965.0) – «Himbeer» (DE 10 2008 038 937.4) Trademarks, «sorten» and other IP: – to be filed – individual products to be protected later.

26 Timelines Projected start: April 2010 Ready for business: August 2010 – starting with parts A+B – other parts (including «YOGI») concomitantly if sufficient staff and funding are available. 1 st milestone: April 2012 – proof of principle for parts A+B – start parts C+D if not begun before – decision on «add-on» project parts. 2 nd milestone: April 2013 – core project completed, including P.o.P. for C+D – other parts depending on staff and funding – evaluation of progress in «add-on» parts

27 Spin-Offs & By-Products Various applications of the plants – food, fodder, fuel as mentioned above – technical systems incorporating these plants: – waste water plants – zero-emission power plants Further applications of the technology: – e.g. the «YOGI» technology for the study of molecular interactions: – commercially useful enzymes – therapeutics and diagnostics – rapid treatment of emergent diseases (Ebola and friends) – affordable personalized therapy (cancer) – with DE102007005191.5: drug delivery system – with DE102007005192.3: possibly treatment of in- flammatory and degenerative diseases
