PSB Photosynthetic Bacteria (Home Cultured) 5L (2L x 2 bottles + 500ml x 2 bottles)

★ Listing for Mercari

Thank you for viewing.

We are offering 5L of PSB photosynthetic bacteria (2L x 2 bottles + 500ml x 2 bottles) cultured in our home for medaka breeding.

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

★ The color (hue, tone, appearance) 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, tone, appearance) or are sensitive.

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

Also, the number of days cultured is reflected in the price (labor cost) at a minimum, so we cannot offer it for less than necessary.

★ Quality and Trust > Price

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

★ Eco-Mercari便 (Delivery to Doorstep): For Kanto, Chubu, Kinki regions (See Guide → Delivery Method) → If you can permit receipt, we will include 500ml of PSB or 50 units of culture medium.
Please check Permit Receipt before purchasing.

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 after arrival.

Please open outdoors and adjust the volume.
