This week in the Flog:
- Making Lactobacillus Serum
- Photos to go with the recipe!
I finally ran out of lacto serum! It gives me an opportunity to finally publish pictures to go with this recipe. So let’s look at the process from start to finish with pictures.
I didn’t have rice wash handy for the first step. But I did have cheerios. There you go, great carbohydrate source. Not as ideal as a bran cereal or rice wash, but it will do just fine for the purpose of attracting wild microbes. Here is the ‘rice wash vessel’ with at least half air, and open on top. I left the Cheerios in for about 5 minutes, until they started really shedding into the water. Here they are getting soggy:
I strained out the cheerios, and loosely secured some mesh netting over the top so that large critters like cockroaches can’t get in. This is my carbohydrate wash that will sit out for 5-7 days:
Now the vessel sits in a shady area of the garden for 6 days. After 6 days it’s pretty cloudy and you can see ‘threads’ in it – bacterial growths. No separating into layers but that’s ok, it will work fine. I drained off most of this solution since I’ll use the same vessel for the milk, and I need 10 parts milk. So I drained until just about 1/10th the vessel was wash water:
Now we add the milk – just regular old UHT processed milk, nothing special. Although natural cow’s milk would be the absolute best. I put the lid of the jar on top but not clamped down. This creates a seal but if gas builds up it can escape if needed:
Jar goes back to the shady corner of the garden. Now wait another 7 days. The curd on top starts out pretty thick and gets thinner, while the solution turns very cloudy white. It’s pretty sweet. Here is the jar after 7 days:
Now I used the same mesh, in combo with a funnel, to make a strainer to transfer the solution into a plastic jug. Then just pour out the lacto serum:
Now we have the lacto serum separated out, it needs sugar to stabilize it for storage. I have about 750ml of serum, so it needs either 750ml of molasses or 750gm of sugar. I had nice brown sugar handy, cost <1$ so I like the price vs molasses here. I weighed out around 750gm of brown sugar to be added. Here they are: [caption id="attachment_830" align="aligncenter" width="500"] Sugar and Lactic Acid Bacteria (LAB) ready to be mixed[/caption]
Conveniently I had a 1.5L bottle handy which I added the serum to initially. After adding the sugar, the solution is almost up to the top. Just perfect:
After a few shakes, the sugar dissolves and the solution becomes a bit thicker consistency, with few bubbles. It’s as easy as that. Now I have 1.5L of pure stabilized lacto serum.
- Store this pure solution I’ve just made above wherever, in my home office for now.
- Get 500ml bottle and add 2tbsp of this pure lacto to that bottle and fill to top with clean, un-chlorinated water
- Use this 500ml bottle for all the applications I use lacto for around the house/balcony
- 2tbsp per meal, after we eat, mixed in half glass of water
- 1tbsp/L (or less) sprayed everywhere indoors – to kill all those humid-country-tropical-smells that somehow crop up
- 1tbsp/L to spray plants, foliar feed keep their leaf surface healthy (equivalent to us using after meals)
- 1tbsp/L when watering compost piles, keep them moist when they dry out
- 1tsp/L in roach water, dog’s water
- 2tbsp/L for periodic moistening of Bokashi bran and when adding stuff to bokashi bin
- 2+tbsp/L drain cleaning – inundate at night after we finish using sinks/toilets
- 2+tbsp/L grease trap cleaning – in Philippines sinks have bins below them that are grease traps that get super smelly. This kills it
- 1tbsp/L added to water bucket with organic fertilizer, 12-24hrs before watering plants (usually night before)
Pretty cool huh? I guess now I need to write a post showing all those applications. The smell killing is a pretty cool one. I should get a video. You can kill smells in 10mins flat. You can have something rotting on your balcony, to the point it makes your eyes water to stand out there. Spray it with a strong lacto mix (5tbsp/L or something). Come out to the balcony 15mins later, and you don’t even know there is some rotting thing there next to you. I speak from personal experience. Hah.
In any case, here is the illustrated lacto serum recipe. Please, share your experiences with lacto, what you’ve used it for and how it’s worked for you. Ideas grow by sharing.
Keep on growing.
