Establish and preserve your own master culture with our premium King Blue Oyster Slant Culture grown on Malt Extract Agar (MEA). King Blue Oyster (Pleurotus ostreatus) is produced from carefully selected commercial genetics chosen for vigorous mycelial growth, rapid colonization, dense cluster formation, excellent biological efficiency, and consistent yields. This fully colonized agar slant serves as a clean starting point for expanding onto fresh agar, preparing liquid cultures, producing grain spawn, or preserving genetics for medium- to long-term storage.
Every culture is prepared under strict aseptic laboratory conditions and inspected before shipment to ensure a healthy, actively growing culture. King Blue Oyster is valued for its large blue-gray caps, thick, meaty texture, excellent yields, and dependable cultivation performance, making it a favorite among gourmet mushroom growers for both home and commercial production. Slant cultures are ideal for experienced cultivators, researchers, educational laboratories, and commercial mushroom growers seeking a reliable method for maintaining and propagating stable genetics.
