We resurrected Typhlops cubae Bibron, 1843, a species considered as a nomen dubium for the past 55 years. Based on a designated lectotype and nearly 80 additional specimens, we redescribed the species and compare it with other congeners from the Bahamas, Cuba, and Hispaniola Islands. We found that Typhlops cubae is related to the Typhlops lumbricalis species group, restricting its distribution to western Cuba and Isla de la Juventud, and overlapping with Typhlops pachyrhinus along the Pinar del Río and Artemisa provinces.

Microbes able to convert gaseous one-carbon (C1) waste feedstocks are increasingly important to transition to the sustainable production of renewable chemicals and fuels. Acetogens are interesting biocatalysts since gas fermentation using Clostridium autoethanogenum has been commercialised. However, most acetogen strains need complex nutrients, display slow growth, and are not robust for bioreactor fermentations.

We describe 270 genome sequences of solventogenic clostridia from a comprehensive industrial strain collection assembled by Professor David Jones that includes 194 C. beijerinckii, 57 C.
