Thanks for that very interesting. Marmite is British and vegimit is Australian. Fun fact because Marmite uses the byproduct of brewing during the lockdown in the UK no beer was being made so there was a shortage of Marmite as well.
Dude, you're awesome! I was searching a recipe for this for a while until this moment! Found your channel by video about your tempeh analogue. Make more content because it is really worth to watch!
Great video mate, love your tech culinary adventures! Just One question, what should i change to use for example grape molasses or must or other to achieve the right result? What Is the Window of possible changes in your doses to get best results? Thanks, All the best!
i live in brazil and we dont have any yeast extract in the markets. i had once a vegemite jar that a friend brought to me from Australia. since then i look for a way to make it at home.
I'am a homebrewer, btw, its gonna be easy to get yeast in large ammounts lol a batch of 40 liters of beer generates aprox. 5 liters of yeast
Vegemite without the tons of salt. Great video.
Where can I find the schematics for that alcohol meter you've made?
You should try and make vegemite, that would be interesting. Vegemite and marmite taste completely different, and New Zealand marmite has its own distinct flavour with no similarities to British marmite.
What are the ratios and when to stop the ferment and if possible how to reduce alcohol
Marmite they mostly just add vegetable stock to it to flavor it.
hey have you thought about doing a btech discord? it'd be so cool to have a community and as a creator you'd have a good foundation to build one :D
That's a good idea! I should get on that!
I second this!
Hey man, I really enjoy your videos. Well-spoken and informative to say the least. I was wondering if could do some experiments with Lactic Acid bacteria>and then ethylene glycol? I have been doing this at home for a few years now and would love a more informative approach with your expertise. Thank you kindly:)
You would like to use lactic acid bacteria to break down ethylene glycol? Like the stuff found in antifreeze?
@@DIYBiotech Sorry for my mixup. Ethylene gas. Fermenting fruits by-product
@@ericblank6232 why do you want ethylene gas? Is it of high value?
no wonder yeast extract is so expensive, so much for so little
The price of sugar is something like 0.5$/kg, the price of yeast extract can be 200$/kg. The inputs are basically worthless, all the cost is processing and QA.
As this video points out, the type of yeast used resulted a lot of ethanol production.
@@mattabestayou mean the raw material is not that expensive, is because of the manufacturing process that make it expensive ?
Reguarding bursting bottle. One might also factor in that yeast are not happy under pressure and increasing acidity from disolved CO2, and that they slow down and may stop.
Dont the dead yeast release gas as they die?
Awesome content! Bear Grylls approves confusedly
Hi, I have also tried this out but have not been able to dry it into powder.
Have you been successful with this, I mean turn it to powder. Like to know.
Thanks
I think you'd have to freeze dry or spray dry to get powder
Hey thanks for the video!
How do you measure the ethanol concentration - Is it a photometric test? If so, at which wavelength?
Thanks!
Rare Combinations LLC. It works like a breathalyzer!
@@DIYBiotech genius! thanks Nick ;)
@@DH-ls9qv a hydrometer may be less accurate, but is used by booze makers across the entire planet including big companies lol. $20 Hydrometer
Hello! I need Yeast Extrakt for face creame but simple. Like in oil or vodka. Is it possible to mix? Will yeast die in such basics??

Hi, two thoughts:
1. Would it not be much easier to just buy a large amount of bakers yeast, suspend it in water and start by autolysing? Value packs are just 20$/kg
2. If you are growing the yeast, is it not easier to let the yeast fall to the bottom of your container, remove the cell-free supernatant and collect the pellet, alternatively you could filter the medium if you're impatient. Starting by removing your yeast from the medium would also mean that trying to exhaust the sugar so as not to contaminate the final product is less of a concern, I'm sure that some of your sticky mess at the end is caramelized sugar. Info on marmite implies it is about as much sugar as protein.
I've never done anything like this, just wondering how this could be done more practically. I love to think about how I could do things myself instead of wasting my precious grant on 200$ yeast extract.
Very cool idea to just buy the packs of yeast! I didn't know this was an option. I think your second point would probably work too!
@@DIYBiotech one of my favorite phemomena, I'll call it, is how something can be so obvious to you but totally escapes you because your mind is preoccupied with so many other variables. It only becomes "obvious" either once someone else suggests it, or you've repeated a process so many times that those steps no longer take up your mind's resources and you begin to naturally come up with alternatives
Interesting. However, where are the acids in your calculation (lactic, aecetic)?
No there weren't! Good thought here! I don't suspect they'd be anything more than a gram per liter though... What do you think?
Is there perhaps a way of growing the yeast in aerobic condition while still keeping the substrate from getting contaminated?
Maybe hooking it up to some food grade oxygen gas canister?
As far as I understand, that should reduce the amount of generated alcohol, so I'm guessing that more sugar would be converted to biomass.
Also it could get rid of the beer aftertaste.
Without having to evaporate the alcohol I'd also not reduce the liquid so heavily -- maybe just to the syrup consistency.
I'd also love to see this being done with some Beta Carotene Yeast (like The Thought Emporium's /watch?v=DHNPnO5UOYQ) :P
Very interesting, keep it up! :D
Definitely could grow aerobically! That's normally how we grow yeast in my lab. Could just add a sterile filter to the top of the bottle to let them breath. This would be very cool to see with the GM yeast!
Airlocks can be had/made for pennies! The water barrier prevents baddies from getting in, a filter on top of THAT prevents anything from infecting your water if for some reason you got a food source in the water
Are the extracted enzymes still working though?
Hmm probably not... You may be able to alter the protocol to keep the enzymatic activity though
Hi sir, can i mix wheat，rye，and oat with brown sugar and wine yeast?
Sure!
@@DIYBiotech Thanks for your reply 🙏☺️
@@DIYBiotechat 6.18, you mentioned wait for 16hours and 135degrees, is it after boil still need to heat it at 135degrees or boil it at 135degrees then wait it for 16hours?
@@badmintonator9696 I think the wait time is to let it settle so you could pour off "clean" liquid
I know its easy and cheap to get yeast for pizza dough or bread like Artisan Bread but if you want to make your own just to keep as backup if its hard to get might be cause of supply chain.
can you share the recipe for how to make your own dry yeast for Pizza?
I'd start with learning how to make a sourdough starter! You can always make your own bread without buying yeast at the store
I do it all the time, but I am looking for the yeast that I have to buy from shop specially for pizza.
@@codeaccount2434 you could grow that yeast in a similar media I used, but the hard part would be lyophilizing (freeze drying) the yeast. I want to one day but those machines are expensive!
@@DIYBiotech sorry bothering you, can you share the actual process of doing that. and link to the site where I can see the equipment.
@@codeaccount2434 just look up "lyophilizer" or "how to make a freeze dryer". The machines are around $10k I think, but DIY versions can be a few hundred dollars probably
Marmite
You added 65g of light brown sugar so its max contribution from your calculations is +28.07g, but the contribution from the 5g yeast you started with isn't accounted for. Comparing from your results, it sounds like ~14% of the 5g yeast bag's mass would go towards the 4g of cell debris, ~14% would go towards the remaining extract, and the rest would have been lost in the same way that was undetermined.
sugar Converted by yeast
interesting topic but too much math for me (I confess that even a little is already too much, I'm allergic)
SULFUR/SULPHUR, not SulfEr, Mr. Science guy.
I would prefer good time panorama of process and nice fonts for symbols, instead of anyone face.
And short poorman recipe is better than numbers. Like it could be science in TikTok, it just too much shite to watch
