If sugar was the main impuruty present in crude acetenilide would recrystalization from water be a good method of purification and why?

Yes. First we know acetneilide is soluble in water only when heated. We also know that sugar is soluble in water before and after heating. Therefore, when our sample cools, and recrystallization begins, the sugar should remain in solution, while the acetenilide crystallizes out. Therefore, when we wash our crystals, the sugar remains in solution and filters out.

Is there any purification needed in yeast fermentation?
That depends on what you mean by purification. In a general sense, yeast can ferment in very unclean environments, but likely will fail to outcompete other microbes that may also be present. Microbes besides brewer's yeast will typically contribute off flavors and aromas to the beer, and may make it completely undrinkable. This is why modern brewers are careful to sanitize the equipment used in the brewing process, from the siphons, hoses, and filters to the vessels in which the beer ferments and is later stored or packaged. As far as water purification goes, modern brewers almost always start with purified (which is to say palatable) water. However, part of the brewing process is boiling the wort (grain soup) that is later fed to the yeast, and the act of boiling itself is a very solid form of purification. In fact this is one of the reasons beer permeated ancient civilization -- because of the boil it was inherently safer to drink than most water sources.
