My suggestion is being able to breed bacteria for many different uses. By being able to genetically modify bacteria or selective breeding, they will be able to do incredible things. To start, you need to craft a petri dish. You have to place a gel onto it and wait until bacteria starts to develop in it. Now, with a syringe, you can place in different chemicals extracted from many different objects to modify it. To get to it's DNA, you have to build a genome analyser machine. When you gets it DNA sequence, build a DNA splicer that will rip apart sections of DNA that you want and join it to other ones. Different types of bacteria have different effects. Some of these effects are to be able turn plants into biofuel. Of course, you should be to make a bacteria to release into the environment and kill flora and fauna. To mass produce the bacteria, make a tank. Place in chemicals and the bacteria and wait for it to grow. Depending on the type of bacteria, it will multiply. E.G, 1,2,4,8,,,,. Tanks can be infected by nearby tanks and produce dangerous products that would give Steve nausea and other nasty effects. However, all the dangers will be worth it of your bacteria turns out to be very beneficial. Suggestions for more effects are welcome! HAYO
