Growth medium as well as freezing menstruum greatly influenced the recovery of Saccharomyces carlsbergensis when it was quickly frozen in liquid nitrogen at - 196 C and quickly thawed at 40 C. Nearly 90% recovery in viability was obtained when S. carlsbergensis was grown in Trypticase Soy Broth and frozen in vitamin B(6) basal assay medium. The growth phase of S. carlsbergensis also influenced ...

Semen samples were collected from eight males of Goldfish (Carassius auratus gibelio) and cryopreserved using four extenders (Goldfish sperm extenders; GFSE 1– GFSE 4) supplemented with Methanol (MeOH) at concentration of 5%, 10% and 20%. Semen was diluted with ratio of 1:1 with extenders and frozen in liquid nitrogen vapor. Frozen sperms after 2 and 5 days were excluded from freezing. Experime...
