  Hi, I am doing an experiment where I test the rate of respiration using different types of sugar. Is it normal that the colour change happens more quickly in my control trial (with only yeast and water) compared to the trial where I use glucose as a substrate. Shouldn't the trial with glucose change colour more quickly? please answer, I am a bit stuck.

• 
  @sixthformbiology3406 ай бұрын

  You are correct. There should be no colour change in your control where there is no substrate glucose, as there should be no respiration. So something has gone wrong. Maybe a mix up with tubes, or your control has some glucose present when it was made up by the technician...

  @@sixthformbiology340 Just to add to this question we're currently trialling this practical with different percentages of glucose yesterday I found the solution with a higher % of glucose took longer to go colourless (back to yeast colour) we're kind of confused we thought it would be quicker the more glucose we used.

  @@sixthformbiology340 Thank you, we've been asked to make a 1% yeast solution with 1%, 5% & 10% glucose after looking online a bit more we might be using the wrong yeast we've got the fast action. Its just odd we've trialled the practical twice now and got the same results.

  hi miss i dont know if your still active but if you are hopefully you can answer my question well miss do i have to write the exact thing for example when you wrote your method you wrote 25 oc water bath would it be ok to just write 25 another example is 2x10 syringe would it be ok to just say syringe

• 
  @sixthformbiology340 Жыл бұрын

  You always need units! 25 could be C or F...so need to say which one. It is always so someone else could see your method then go away and do it from your instructions. What size syringe should they use? Tell them!

  While fermenting a grain and sugar mash to make alcohol I had the idea to run my grain mash through an ultrasound to decrease particle size to make the grain mash more bioavailable to the yeast. The results were incredible. I am wondering if you can also try this on a grain mash and measure the results between the ultrasound mash and a control. I did a very short clip showing my bubbler and fermentation bucket. kzread.info/dash/bejne/qqCVqdyYY9CxmLg.html After this I tried a sugar wash through the ultrasound unit but it did not seem to increase the rate at all. Probably because the dissolved sugar was already at it's smallest size. It did seem to point to the fact that the yeast did better with the smaller particle grain mash than it did with the sugar wash. I really would like to see someone do more testing and research on this as it could have a huge impact in several fields like fuel and space travel. That and I like the idea of giving back to the yeast something it likes for its centuries of service to humankind. #Yeast lives matter. I would love a reply with your thoughts. Been working on soil and foliar fertilizers and making them more bioavailable to the plant microbiology and cell wall penetration. #Nano Nano
