Temer, who took over in May of a year ago after President Dilma Rousseff was impeached and later removed from office, has the lowest approval rating of a president since 1989. He says nothing will "destroy" his government.
Also charged was President Temer's close ally, Rodrigo Santos da Rocha Loures, who supposedly accepted R$500,000 in bribes from Batista in the name of President Temer. The same would happen if Brazil's Supreme Federal Tribunal, the country's highest court, doesn't reach a verdict in the 180 days of the trial.
"Now it's become even more hard to vote anything", said Luis Antonio Covatti, a lawmaker from the Progressive Party in Temer's ruling coalition.
If charges are brought forward, Brazil's lower house of Congress will decide whether to suspend Temer from office to stand trial. "Nothing will destroy us - not me and not our ministers".
The leftist leader was finally dismissed on August 31 and the conservative Temer took full office to see out the mandate to late 2018, launching austerity reforms to fix the stricken economy.
In his decision, Janot said that at some point between March and April of this year Temer took a bribe of around $150,000 offered by Joesly Batista, former chairman of meat-packing giant JBS.
However, Temer's aides say they are confident he has sufficient support in Congress to get the charges thrown out.

The Trump White House has been using the app Confide to communicate to curb leaks to the press, it was reported earlier this year. CREW and NSA say they have the legal standing to sue, though that assertion likely will be challenged by the White House.
In a plea deal, Batista said Temer also condoned payments to imprisoned former House Speaker Eduardo Cunha in exchange for his silence in a corruption investigation.
One of the recordings contains audio in which the president, who is also under investigation for obstruction of justice and illicit association, tried to buy the silence of a former member of Congress now imprisoned for participating in the Petrobras corruption scandal. "There is no Plan B. We have to keep going", he said.
In a further sign of Temer's weakening position, an important figure in his ruling coalition, former president Fernando Henrique Cardoso, called for him to step down and help Brazil hold new elections.
One of the main lines of defense of the president was to denounce a "manipulation" of this "record clandestine", but the expertise of the brazilian police certifies that no editing was performed, revealed Friday, the newspaper Folha de Sao Paulo.

"Of course you could switch the political class with other people but the most corrupt ones in this whole affair would probably escape unharmed", said Nicolas Crapez, 34, on his way to work at the state government in Rio de Janeiro.
Temer's latest approval ratings are just seven percent, lower even than his leftist predecessor Dilma Rousseff, whom he replaced previous year when she was impeached and removed from office by his congressional allies.
For months, he appeared immune to the corruption probes swirling around many of his allies and even a third of his cabinet.
