Another example of biochemical dismutation reaction is the disproportionation of acetaldehyde into ethanol and acetic acid. While in respiration electrons are transferred from substrate (electron donor) to an electron acceptor, in fermentation part of the substrate molecule itself accepts the electrons.he oxidation state of oxygen is -1/2 in the superoxide free radical anion, -1 in hydrogen peroxide and 0 in dioxygen. 1  In the Cannizzaro reaction, an aldehyde is converted into an alcohol and a carboxylic acid. 2  In the related Tishchenko reaction, the organic redox reaction product is the corresponding ester.
SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding TCP ports and X11 connections; it can transfer files using the associated SSH file transfer (SFTP) or secure copy (SCP) protocols.
SFTP, which stands for SSH File Transfer Protocol, or Secure File Transfer Protocol, is a separate protocol packaged with SSH that works in a similar way over a secure connection.he advantage is the ability to leverage a secure connection to transfer files and traverse the filesystem on both the local and remote system. In almost all cases, SFTP is preferable to FTP because of its underlying security features and ability to piggy-back on an SSH connection.
