No, they were not Toxic was actually poinsonous to the Anaerobic photoautotrophs. However cyanobacteria (a.k.a pondscum) is believed to be the first bacteria to give off oxygen as a by-product of photosynthetic processes.
Oxygen is an important by-product (not waste) of photosynthesis and is needed by not only animals and other organisms, but also the plants which make it.
No, photosynthesis. Oxygen is a byproduct of photosynthesis.
oxygen is the byproduct of photosynthesis because from water (H2O), sunlight and carbon dioxide (CO2) , they release oxygen to make glucose.
The development of photosynthesis in primitive organisms, specifically cyanobacteria, contributed most directly to the evidence of aerobic organisms. Photosynthesis evolved around 3 billion years ago, producing oxygen as a byproduct. This oxygen accumulation in the atmosphere eventually allowed for the development of aerobic organisms, which rely on oxygen for their metabolism.
There is a one byproduct. it is the O2 gas.

The main byproduct of photosynthesis is oxygen.

Oxygen and Glucose
The source of oxygen in the atmosphere is a complicate stellar process.
Large quantities of oxygen are dissolved in water and make up a large percentage of air. Organisms extract it from these media. The ultimate source of molecular oxygen in the air and water appears to be as a byproduct of photosynthesis in plants and some single-celled organisms.

It's called oxygen. Very handy stuff if you are into breathing.
