When hydrogen sulfide (H2S) is produced, it reacts with the lead acetate in the SIM (specific ion meter) solution to form lead sulfide, which is a black precipitate. This black precipitate causes the SIM to turn black as well.
Black pigment in the SIM tube typically results from the production of hydrogen sulfide by certain bacteria during metabolic processes. The hydrogen sulfide reacts with iron salts in the medium to form insoluble black iron sulfide, which appears as a black precipitate in the tube.
Gram Stain to determine gram negative and shape or streak on a Agar plate selective for gram negative such as Desoxycholate Agar (DES). A SIM (Sulfur, Indole, Motility) Test or a Kiliger's Iron Agar (KIA) Test can confirm the production of H2S. *I would choose Streaking on DES to isolate the gram Negative bacteria, and then stab inoculate a SIM tube. Black precipitate confirms H2S production positive.
You will do this regardless since Indole is part of the SIM media....this media will turn black if H2S is present and you read it for motility just like standard motility media. It must incubate for 24-28 hrs before doing the indole portion. Hope this helps.
Kliger's iron agar (KIA) and SIM (sulfide, indole, motility) agar are both types of differential media used in microbiology to identify Enterobacteriaceae based on their ability to ferment sugars, produce hydrogen sulfide, and exhibit motility. Both media help differentiate between different bacterial species based on their specific metabolic activities and characteristics.

Ferrous ammonium sulfate acts as a hydrogen sulfide indicator in SIM agar. It reacts with hydrogen sulfide gas produced by certain bacteria to form a black precipitate of ferrous sulfide, indicating the presence of H2S-producing organisms. This helps in differentiating bacteria based on their ability to produce hydrogen sulfide.
Yes, it does. It is Indole Production positive, H2S positive, and Motility positive. This can all be seen using SIM agar. Yes, it does. It is Indole Production positive, H2S positive, and Motility positive. This can all be seen using SIM agar.

Turn it off, and pop in Call of Duty: Black Ops.
You can't turn an alien sim back to normal in the sims 2 for the pc. They really aren't different from regular sims except for that they have green skin and maybe even black eyes.
Your sims can not turn into an alien but u can create a sim as an alien by clicking on what skin color for your sim
A werewolve has to bite your sim but they have to become good friends.
You have your sim befriend the wolf pack leader (the wolf with glowing eyes), and then get it to bite your sim.
You need to have Sims 2: Pets to be able to turn your Sim into a werewolf.To turn your Sim into a werewolf, you need to build up a relationship with the Leader of the Pack (who is the yellow-eyed wolf, who comes onto Sims' lots at night). Eventually, when the relationship level between your Sim and him is high enough, he will give your Sim a gentle nibble, turning your Sim into a werewolf.Note that Sims become werewolves at night; by day, they are human.
