World's Largest Sitka Spruce Tree. A celebrated Sitka spruce (Picea sitchensis) on Klootchy Creek near Seaside, Oregon, receives so many visitors that recently a $50,000 boardwalk was constructed to preserve its roots from compaction. It is perhaps 700 years old, and truly amazing in stature.
Bacteriocins are antibacterial proteins produced by bacteria that kill or inhibit the growth of other bacteria. Many lactic acid bacteria (LAB) produce a high diversity of different bacteriocins. Though these bacteriocins are produced by LAB found in numerous fermented and non-fermented foods, nisin is currently the only bacteriocin widely used as a food preservative.
Report Abuse. A bacteriophage (from 'bacteria' and Greek phagein, 'to eat') is a virus that infects bacteria. The term is commonly used in its shortened form, phage. Like viruses that infect eukaryotes (plants, animals and fungi), a large diversity of phage structures and functions exist.edit] Replication Bacteriophages may have a lytic cycle or a lysogenic cycle, however a few viruses are capable of carrying out both. In the lytic cycle, characteristic of virulent phages such as the T4 phage, host cells will be broken open (lysed) and suffer death after immediate replication of the virion.
