Draft genome sequence of Staphylococcus auricularis PAPLE_T1 isolate of Carica papaya revealing biosynthetic clusters for beneficial metabolites. Microbiol Resour Announc 2024; 13:e0120123. [PMID: 38456700 PMCID: PMC11008150 DOI: 10.1128/mra.01201-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 02/24/2024] [Indexed: 03/09/2024] Open
Abstract
Genomic features of Staphylococcus auricularis PAPLE_T1 isolated from waste sample of Carica papaya obtained from Lagos State, Nigeria, revealed its putative capability to synthesize valuable secondary metabolites. S. auricularis PAPLE_T1 has a 2.4 Mb genome and could be useful as biological agro-antibiotics, for soil bioremediation and in biotechnological industry.

Hamilton A, Bots P, Zhou H, Liu B, Hall C. Clean-up of divalent cobalt ions by massive sequestration in a low-cost calcium silicate hydrate material. Sci Rep 2024; 14:7052. [PMID: 38528006 DOI: 10.1038/s41598-024-56617-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 03/08/2024] [Indexed: 03/27/2024] Open
Abstract
Cobalt is a critical resource in industrial economies for the manufacture of electric-vehicle batteries, alloys, magnets, and catalysts, but has acute supply-chain risks and poses a threat to the environment. Large-scale sequestration of cobalt in low-cost materials under mild conditions opens a path to cobalt recycling, recovery and environmental clean-up. We describe such sequestration of cobalt by a widely available commercial calcium silicate material containing the mineral xonotlite. Xonotlite rapidly and spontaneously takes up 40 percent of its weight of cobalt under ambient conditions of temperature and pressure and reduces dissolved cobalt concentrations to low parts per million. A new Sharp Front experimental design is used to obtain kinetic and chemical information. Sequestration occurs by a coupled dissolution-precipitation replacement mechanism. The cobalt silicate reaction product is largely amorphous but has phyllosilicate features.

Analysis of phenotypic changes in high temperature and low pH extreme conditions of Alicyclobacillus sendaiensis PA2 related with the cell wall and sporulation genes. Arch Microbiol 2024; 206:53. [PMID: 38180563 DOI: 10.1007/s00203-023-03735-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 11/01/2023] [Accepted: 11/04/2023] [Indexed: 01/06/2024]
Abstract
The A. sendaiensis PA2 is a polyextremophile bacterium. In this study, we analyze the A. sendaiensis PA2 genome. The genome was assembled and annotated. The A. sendaiensis PA2 genome structure consists of a 2,956,928 bp long chromosome and 62.77% of G + C content. 3056 CDSs were predicted, and 2921 genes were assigned to a putative function. The ANIm and ANIb value resulted in 97.17% and 96.65%, the DDH value was 75.5%, and the value of TETRA (Z-score) was 0.98. Comparative genomic analyses indicated that three systems are enriched in A. sendaiensis PA2. This strain has phenotypic changes in cell wall during batch culture at 65 °C, pH 5.0 and without carbon and nitrogen source. The presence of unique genes of cell wall and sporulation subsystem could be related to the adaptation of A. sendaiensis PA2 to hostile conditions.
