What kind of lifeforms could live on Venus?
When we are talking about life on Venus, that lifeform would be the anaerobic prokaryote (but it can also be eukaryote) or archon. If the bacteria is like this that organism is using the carbon dioxide on the planet, and maybe photosynthesis or high temperature for creating energy for its chemical processes. That means that this bacteria would be similar, what lives near volcanic eruption holes, and there is a possibility, that those suspected bacteria can live only at the mountain areas of that planet.
If those bacteria are endemic, which means that they are formed at Venus, that thing means that they are fully adapted in their environment. So Venus is the paradise for those organisms. But there is a possibility that those organisms are traveled to that planet onboard some space probe, which is not well sterilized.
And there is a possibility that the high surface temperature (464 Celsius) is believed along with high pressure about 92 bar(92 times of sea level at Earth atmosphere (the pressure on seal level on Earth is 1,013 bar) ) to destroy all living organisms. But if the parachutes of probes are opened high enough, that thing would deliver the sulfur-eating bacteria to the clouds of that planet. And at highlands, the temperature is lower than the lowlands.
Before the sophisticated laboratories are analyzed the samples, those bacteria are only a strong hypothesis, what bases the observations of chemicals, what are forming only in the metabolism of living organisms. And when the samples are taken the thing, the next mission is to analyze the genomes, what can confirm is the bacteria similar, what lives on Earth? That means that bacteria might travel in some probes.
Those organisms can be left to the atmosphere when parachutes of the Venus probes are opened above the cloud layer. And the key question is, is that organism endemic species of planet Venus? If those bacteria are endemic, that would be the scientific sensation of the millennium.
