Bringing tissue tradition manufacturing into the twenty first century


Greg Lowe from Lowes TC is on a mission to automate tissue tradition manufacturing, making it extra reasonably priced to supply excessive well being clonal crops on this nation. Discover out about his enterprise’ new TC+TM liquid media momentary immersion system bioreactor and automatic manufacturing methods.

Greg Lowe is the Director of Analysis & Growth at Lowes TC, an Australian owned enterprise specialising in plant tissue tradition propagation. Lowes TC presently provide over 100,000 crops every week for the Australian trade. Nonetheless, Greg believes that Lowes TC can produce many extra crops by way of automation.



“Industrial plant tissue tradition (TC) began within the early 1960’s. As we speak’s lab appears the identical as then. It has a excessive labour enter with little to no automation. Not surprisingly, the worldwide TC trade has primarily positioned to low wage international locations,” says Greg. Regardless of growing demand for top well being clonal plant propagation (HHCPP) in lots of international locations, TC manufacturing continues to stay costly when in comparison with options similar to unrooted cuttings (URCs).
Greg claims that URCs may be produced for as little as 5 to 10 cents in some international locations, factoring in a few further cents for air freight and different prices. He estimates that each plant that comes out of TC manufacturing in Australia has between 30 to 50 cents price of labour in it. TC due to this fact can not presently compete with URCs on price, particularly when present TC methods are restricted to producing round 200 crops per hour.

Lowes TC+TM Bioreactor – Patented know-how

Over the past three years, Greg has been researching strategies to enhance and automate TC manufacturing. Nonetheless, Greg discovered that not one of the present protocols utilizing small jars of agar in them labored with the automation that he had in thoughts.



“We principally got here up with a liquid media momentary immersion system bioreactor. It’s referred to as a brief immersion bioreactor as a result of pressurized air strikes the liquid media up into the plant rising chamber for a couple of minutes each eight hours. This liquid media waters and fertilises the crops earlier than draining away. The crops due to this fact stay in a dry setting in order that they will develop usually,” Greg says.
Though liquid media bioreactors have been round for the reason that 1970’s, present merchandise don’t enable for straightforward automation. To keep away from hygienic seals breaking underneath excessive strain, these bioreactors have chambers with small openings fitted with a rubber seal tightened onto a screw thread. This small opening makes it tough to take away the crops from the chamber with out contaminating the plant.
“We had to determine a approach of transferring media into the rising chamber and out of it with out utilizing excessive strain air. We reduce the container in half on the widest level and put a giant seal throughout it in order that we are able to open it up and have full entry to 100% of the container from above. And that entry permits us to then use the automation,” Greg explains.

Lowes TC Automated Propagation

“We realized what we might do with the automation is enhance the supplies dealing with course of. Each time we contact the bioreactor, we’re transferring 150 or 400 crops, so we’re not touching them one by one. We contact them in mass, and we produce them in mass,” Greg says. Lowes TC automated propagation entails a easy supplies dealing with course of utilizing conveyors and choose and place instruments. It does although have the potential to be totally automated with robots.
“With the management that we are able to get in our TC+TM bioreactors, we are able to improve the air circulate within the bioreactor, and we are able to begin to harden the plant. By the automation course of, we are able to additionally put the crops right into a rising medium in a plug tray contained in the container and begin the roots creating in a traditional plug combine. The cuticles begin to harden, and the stomata begin to work. They’re nonetheless softer after they come out than a traditional plant out of a greenhouse. Nonetheless, they’re much hardier than a tissue tradition. And since they’re already in somewhat plug tray, you do not have to plant them by hand. You simply put them into an present automation system,” Greg explains.

Accelerating Commercialisation Grant

“Everybody who has really seen the automation course of has the identical response. They are saying, hasn’t somebody considered this earlier than?”, says Greg.
The Federal Authorities agreed, awarding Lowes TC an Accelerating Commercialisation Grant to construct a pilot plant and develop additional prototypes. Lowes TC obtained greater than $880,000 matched funding by way of the Division of Business, Innovation and Science Enterprise Entrepreneurs’ Programme.



The pilot plant presently incorporates round one thousand bioreactors during which multiple hundred plant genera are being examined. The primary two crops to finish a complete manufacturing run within the TC+TM bioreactor have been dianellas and lomandras, common landscaping crops. “We beforehand had points with Dianella ‘Little Jess’. It was not very worthwhile in regular tissue tradition. We put it into the TC+TM system and we’ve turned that round utterly. It actually made an enormous distinction. Now all our Dianella ‘Little Jess’ is produced within the new system,” says Greg.

Commercialisation plans
Greg claims that this new bioreactor know-how will double the capability of Lowes TC’s Tumbi Umbi facility. It has already elevated yield by 100% on some crops and diminished the labour price by as much as 30% on some crops throughout trials. He believes that this know-how has the potential to interchange plenty of URC and seed manufacturing.

Lowes TC just lately signed a licence permitting Sugar Analysis Australia to make use of its new know-how to supply sugarcane inside Australia for the following 10 years. Sugar Analysis Australia have additionally dedicated to placing on a researcher at their Brisbane workplace to work on creating protocols for sugar cane throughout the TC+TM system.

With patents pending in Australia and abroad for each Lowes TC rising and automation methods, Greg is eager to debate potential collaboration with different propagators throughout the productive, forestry and decorative sectors of horticulture. “It is an enormous, enormous trade and we principally really feel that there is plenty of potential if we are able to get the volumes proper. Nonetheless, we don’t wish to grow to be a giga manufacturing facility. We simply wish to license our know-how, see if it really works for you, and determine tips on how to get that and to gather a really small royalty per plant. So that’s our commercialisation plan,” Greg explains.
