    Abstract Environmental challenges related to the mismanagement of plastic waste became even more evident during the COVID-19 pandemic. The need for new solutions regarding the use of plastics came to the forefront again. Polyhydroxyalkanoates (PHA) have demonstrated their ability to replace conventional plastics, especially in packaging. Its biodegradability and biocompatibility makes this material a sustainable solution. The cost of PHA production and some weak physical properties compared to synthetic polymers remain as the main barriers to its implementation in the industry. The scientific community has been trying to solve these disadvantages associated with PHA. This review seeks to frame the role of PHA and bioplastics as substitutes for conventional plastics for a more sustainable future. It is focused on the bacterial production of PHA, highlighting the current limitations of the production process and, consequently, its implementation in the industry, as well as reviewing the alternatives to turn the production of bioplastics into a sustainable and circular economy.

    Abstract Bursaphelenchus xylophilus, also known as pinewood nematode (PWN), is the pathogenic agent of pine wilt disease (PWD), which affects pine trees around the world. Infection spread globally through international wood commerce and locally by vector beetles, threatening the wood world economy. As climate changes, more countries are becoming susceptible to PWD and, to prevent disease spread and limit economic and ecological losses, better knowledge about this pathogenic agent is needed. Serratia strains, present in the endophytic community of pine trees and carried by PWN, may play an important role in PWD. This work aimed to better understand the interaction between Serratia strains and B. xylophilus and to assess the nematicidal potential of serratomolide-like molecules produced by Serratia strains. Serrawettin gene presence was evaluated in selected Serratia strains. Mortality tests were performed with bacteria supernatants, and extracted amino lipids, against Caenorhabditis elegans (model organism) and B. xylophilus to determine their nematicidal potential. Attraction tests were performed with C. elegans. Concentrated supernatants of Serratia strains with serratamolide-like lipopeptides were able to kill more than 77% of B. xylophilus after 72 h. Eight specific amino lipids showed a high nematicidal activity against B. xylophilus. We conclude that, for some Serratia strains, their supernatants and specific amino lipids showed nematicidal activity against B. xylophilus.

    Abstract Serratia strains are ubiquitous microorganisms with the ability to produce serratomolides, such as serrawettins. These extracellular lipopeptides are described as biocides against many bacteria and fungi and may have a nematicidal activity against phytopathogenic nematodes. Serrawettins W1 and W2 from different strains have different structures that might be correlated with distinct genomic organizations. This work used comparative genomics to determine the distribution and the organization of the serrawettins biosynthetic gene clusters in all the 84 publicly available genomes of the Serratia genus. The serrawettin W1 and W2 gene clusters’ organization was established using antiSMASH software and compared with single and short data previously described for YD25ᵀSerratia. Here, the serrawettin W1 gene clusters’ organization is reported for the first time. The serrawettin W1 biosynthetic gene swrW was present in 17 Serratia genomes. Eighty different coding sequence (CDS) were assigned to the W1 gene cluster, 13 being common to all clusters. The serrawettin W2 swrA gene was present in 11 Serratia genomes. The W2 gene clusters included 68 CDS with 24 present in all the clusters. The genomic analysis showed the swrA gene constitutes five modules, four with three domains and one with four domains, while the swrW gene constitutes one module with four domains. This work identified four genes common to all serrawettin gene clusters, highlighting their essential potential in the serrawettins biosynthetic process.

    Abstract Seven endophytic strains were isolated from the halophyte Halimione portulacoides, collected from Ria de Aveiro, Portugal. To determine their exact taxonomic position, comparative analyses were performed with these strains and closely related type strains of Salinicola species. Genome sequencing and comparison indicated that five of the seven isolated strains comprised distinct and novel species (average nucleotide identity <0.95; in silico DNA-DNA hybridization <70 %; G+C difference >1 %). Multilocus sequence analysis was performed using gyrB, rpoD and 16S rRNA gene sequences from the novel and type strains to determine their phylogenetic positions. The novel strains are facultative anaerobes, mesophilic, facultative alkaliphic and halophilic, test positive for catalase and oxidase activities, for hydrolysis of Tween 20 and phosphate, for production of indole-3-acetic acid, but do not produce H2S. Ubiquinone UQ-9 is present in major amounts in all strains. The major fatty acids include C16 : 0 and the summed feature containing C18 : 1ω7c and/or C18 : 1ω6c. The DNA G+C content ranges from 60.6 to 65.8 mol%. Five strains were confirmed as new species belonging to the genus Salinicola, for which the names Salinicolahalimionae sp. nov. (type strain CPA60

    Abstract Bacterial strain A37T2(T) was isolated from the endophytic microbial community of a Pinus pinaster tree trunk and characterized. Strain A37T2(T) was Gram-stain-negative, formed rod-shaped cells, and grew optimally at 26-30 °C and at pH 5.5-7.5. The G+C content of the DNA was 46.6 mol%. The major respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were C16 : 1ω5c and iso-C15 : 0, representing 61.7 % of the total fatty acids. The polar lipids consisted of phosphatidylethanolamine, four unidentified aminophospholipids, one unidentified phospholipid, two unidentified aminolipids and three unidentified lipids. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain A37T2(T) belonged to the family Chitinophagaceae, forming a distinct branch with Chitinophaga niabensis JS13-10(T) within the genus Chitinophaga. Strain A37T2(T) shared between 92.7 and 95.1 % 16S rRNA gene sequence similarity with the type strains of species of the genus Chitinophaga. The phylogenetic, phenotypic and chemotaxonomic data presented indicate that strain A37T2(T) represents a novel species of the genus Chitinophaga, for which the name Chitinophaga costaii sp. nov. is proposed. The type strain is A37T2(T) ( = CIP 110584(T) = LMG 27458(T)). An emended description of Chitinophaga niabensis JS13-10(T) is also proposed.
