Produce Acid

The organism VH/CN-71 which had been isolated from a growth in a cat and described initially as an "unusual strain of Nocardia" is a streptomycete. This organism can also produce acid from melibiose although it is unable to decompose xanthine. Its sporophores are short, hooked, curved, or open-looped with extended spirals. Present data suggest that VH/CN-71 may belong to the "flavus" series of Streptomyces.

Additional Channel

Controlling, and in many cases minimizing, friction is a goal that has long been pursued in history. From the classic Amontons–Coulomb law to the recent nanoscale experiments, the steady-state friction is found to be an inherent property of a sliding interface, which typically cannot be altered on demand. In this work, we show that the friction on a graphene sheet can be tuned reversibly by simple mechanical straining. In particular, by applying a tensile strain (up to 0.60%), we are able to achieve a superlubric state (coefficient of friction nearly 0.001) on a suspended graphene. Our atomistic simulations together with atomically resolved friction images reveal that the in-plane strain effectively modulates the flexibility of graphene. Consequently, the local pinning capability of the contact interface is changed, resulting in the unusual strain-dependent frictional behavior. This work demonstrates that the deformability of atomic-scale structures can provide an additional channel of regulating the friction of contact interfaces involving configurationally flexible materials.
