Cyanobacteria to speed up photosynthesis

Hello everyone,
I am looking into speeding up the photosynthesis in my plants to get the same results of CO2 without CO2. Apparently cyanobacteria increases photosynthesis and after doing a little research, it seems to be mostly associated with root slime/rot. Now i don’t know if Its a specific strain that causes root problems but i was wondering if anyone has any info about using it to speedup photosynthesis.
Thx

as i understood the topic, these bacteria do not increase photosynthesis... but instead give the plants a better opportunity to fix co2. it's about a special enzyme... i can't remember the name... but i have a report somewhere from the max plank institute about it... i'm looking for it, maybe your answers can be found there

Photosynthesis is a fundamental biological process that allows plants to use light energy for their growth. Most life forms on Earth depend directly or indirectly on photosynthesis. Researchers at the Max Planck Institute of Biochemistry in Martinsried near Munich, together with colleagues from the Australian National University, have investigated the formation of carboxysomes - a structure that increases the efficiency of photosynthesis in aquatic bacteria. Their findings, now published in Nature, could lead to the development of plants with more efficient photosynthesis and thus higher crop yields.

With a global population growth of an estimated 80 million people annually, the demand for food is also steadily increasing. To meet this need, scientists are working on strategies to increase the productivity of crops.
Photosynthesis – crucial, but inefficient
While most organisms rely on the absorption of nutrients to generate energy for their cells, plants, as well as some species of microbes, can provide their cells with light energy. In a process called photosynthesis, they convert water and carbon dioxide (CO2) into sugar and oxygen with the help of sunlight. Decisive for this reaction is the enzyme Rubisco, which is responsible for the fixation of CO2 from the atmosphere. However, Rubisco, which is considered the most abundant enzyme on Earth, works slowly and ineffectively. Instead of fixing CO2, Rubisco can also react with oxygen.
A lot of energy is lost in this side reaction. That's why scientists are trying to develop a more efficient version of Rubisco to promote plant growth. A team led by Manajit Hayer-Hartl, head of the research group "Chaperonin-mediated protein folding" at the Max Planck Institute of Biochemistry in Martinsried, has now made an important contribution to these efforts.

Cyanobacteria are aquatic microbes that perform photosynthesis. They have developed a strategy that increases the efficiency of their Rubisco enzyme. For this purpose, the cyanobacteria increase the CO2 concentration in special structures, the so-called carboxysomes, and limit their Rubisco to these structures. In this way, they reduce the energy loss caused by the secondary reak
In the new study, it has now been shown how the formation of carboxysomes is initiated.

Capture Rubisco for extra energy
Cyanobacteria use the helper protein CcmM to capture Rubisco. CcmM consists of several repeating modules that resemble the small subunit of the Rubisco. Therefore, it was long assumed that these modules replace the small Rubisco subunits when the proteins interact and thus connect Rubisco proteins with each other. However, the complex between CcmM and Rubisco is characterized by a high dynamic and therefore could not be elucidated by traditional methods of structural biology. "In this study, we used the advantages of rapidly developing cryo-electron microscopy to capture these dynamic interactions," explains Huping Wang, one of the first authors of the study. With the help of cryo-EM, the researchers were able to prove that CcmM does not replace the small subunit of Rubisco, but links Rubisco proteins together via an unexpected mechanism.

The interaction between CcmM and Rubisco causes the segregation of the protein complex from other proteins in the cell. "This segregation of proteins is called phase separation and is a process in which proteins are concentrated locally. In cyanobacteria, the protein shell of the carboxysome then forms around the phase-separated CcmM and Rubisco in order to capture them," says Xiao Yan, also first author of the study.
A similar process of phase separation of proteins is also involved in the development of neurodegenerative diseases such as amyotrophic lateral sclerosis.

Carboxysome formation promotes photosynthesis because these microcomparactants increase the CO2 content in the vicinity of Rubisco and thus allow the enzyme to work more efficiently. The current results of the study contribute enormously to improving the understanding of how these CO2-concentrating structures are formed. Manajit Hayer-Hartl describes a possible application of the study results: "If we could transfer functioning carboxysomes to higher plants, this would additionally stimulate the crops to fix CO2 even more efficiently. Then the energy normally lost in Rubisco's reaction with oxygen would be available for the production of biomass."

In the long term, Hayer-Hartl's research findings could help to breed more efficient crops, reduce the use of artificial fertilizers and improve the global food supply. [CW]

Are cyanobacteria toxic to humans?

Drinking water from stagnant ponds and dugouts during hot, dry weather can cause sudden death in animals. This water can contain certain species of cyanobacteria (glue-green algae) are toxic. Cyanobacteria produce neuro and liver toxins that are poisonous to nearly all livestock, wildlife and humans.

it sounds to me as if they will try to research the possibility of a genetic modification, like an insertion of bacterial DNA, into the future food plants.

i like science and how some people push the boundaries...i'm just here as a sort of sheepdog...making sure no really stupid shit slips under the door

I love Shepherd Dogs
because I think there will be a lot of shit slipping through the door.
it's all about profits... Reduce costs Maximize profits... the health of nature, of man, of the entire environment is completely unimportant... what interests these corporations which diseases you get in 5 years. they only see that they can now make the same amount of coal.

we will all have to be very vigilant... not only the dogs among us. a good example is the new vaccines against our disease... demonstrably a higher risk of receiving serious side effects than the actual benefit. this is how it will happen constantly in the future.

Also nitrous oxide (laughing gas) so it's not all bad. :D

Lol, ya.. No doubt the scientists are doing everything they can to fix earths problems in the name of climate change while they have nuclear power plants running and dumping nuclear waste anywhere they see fit. I have no problems sleeping at night and every morning i wake up, i am so proud to be part of this world like everyone else right?

Not all cyanobacteria produce toxins.

Spirulina is a biomass of cyanobacteria that can be consumed by humans and animals.
Spirulina is one of my favorite things to feed my plants too. Also Chlorella and other Sea Kelps including green, red, brown, yellow, orange, purple if I can find it.
