PSB Photosynthetic Bacteria (Home Cultured) 8000ml (2L x 4 bottles) ⑤

★ Listing for Mercari

Thank you for viewing.

We are offering 8L (4 x 2L bottles) of PSB photosynthetic bacteria, cultured in our home for raising medaka.

We manage by the start date of cultivation, so we will provide the most concentrated ones first.

★ The color (hue, shade, tone) of PSB varies depending on the culture medium (food), so the color will differ from seller to seller.
Naturally, it may differ from what you have used before.
There are differences even among manufacturer products.
Please refrain from purchasing if you are particular about color (hue, shade, tone) or are sensitive.

We only provide fully cultured products, so we will cancel all listings if we determine that we only have thin ones due to insufficient culturing time.

Also, the culturing days are reflected in the price (labor cost) at a minimum, so we cannot offer them for less than that.

★ Quality & Trust > Price

If you need the culturing recipe, please let us know via message.

★ Eco-Mercari便 (Delivery to Doorstep): For Kanto, Chubu, Kinki regions (for details, see Guide → Shipping Method) → If you can permit receipt, we will include 500ml of PSB or 50 culture agents.
Please purchase after checking the Permit Receipt box.
If it does not appear on this transaction screen, it will not be eligible.

As these are anaerobic bacteria, the liquid is filled to the brim without introducing air.

It has a strong odor when spilled, so please avoid opening the lid indoors upon arrival.

Please open outdoors and adjust the volume.
