“…as the major genera present. This can probably be due to the increased phytoplankton production during the monsoon season and their associated synthesis of anti-bacterial compounds, which largely restricted the growth of another major genus of Firmicutes such as Staphylococcus, which are prevalent in other seasons (Shannon and Abu-Ghannam 2016;Mühlenbruch et al 2018;Isaacs et al 2021). Such conditions also favored the growth of bacteria of the genus Micrococcus sp., and Actinomycetia sp.…”

Understanding the functional profiles of cultivable bacterial communities is crucial for comprehending their ecological significance in marine environments. This study investigates the functional profiles of cultivable bacterial communities in the water and sediments during the productive, southwest monsoon season, along the west coast of India. The southwest monsoon plays a vital role in shaping the hydrological and biogeochemical characteristics of this region, making it an ideal period to study bacterial communities and their functions. Our study utilizes a cultivation techniques to study taxonomy as well as functional assays to elucidate the diverse organic substrates utilization capabilities of bacterial communities. Cultivable bacteria were isolated from discrete water depths and sediment samples from the coastal and off-shore region. Subsequently the carbohydrase, lipase and protease assays were performed to assess its functional potential. The results of this study reveal a rich diversity of cultivable bacterial communities including, representative from Proteobacteria, Firmicutes and Actinobacterial phylum with diverse functional profiles. The functional analyses provide insights into the metabolic capabilities of the bacteria, including organic substrates degradation, processes. The bacterial taxonomic diversity and enzymes activities were significantly different (p < 0.001) among the water and sediment bacterial morphotypes. In conclusion, this research sheds light on the functional profiles of cultivable bacterial communities in the water and sediments along the west coast of India during the productive southwest monsoon season. The comprehensive analysis of their functional capabilities provides insights into their ecological roles and potential significance in organic matter recycling. These findings contribute to our understanding of microbial diversity and ecosystem functioning in coastal environments and lay the groundwork for further research on harnessing the significance of these bacteria in biogeochemical cycling.

“…Recently, FA profiles have been extensively used to identify various groups of organisms, such as bacteria [14,38,39], sponges [40], microalgae [14,41,42] and fungi [43]. They have also become a promising tool for studying the evolution of biosynthetic pathways and clarifying phylogenetic relationships between taxa in the plant kingdom [44][45][46].…”

Fatty Acid Profiles of Some Siberian Bryophytes and Prospects of Their Use in Chemotaxonomy

et al. 2023

The composition of fatty acids (FAs) in gametophyte samples of 20 Siberian bryophyte species from four orders of mosses and four orders of liverworts collected in relatively cold months (April and/or October) was examined. FA profiles were obtained using gas chromatography. Thirty-seven FAs were found, from 12:0 to 26:0; they included mono-, polyunsaturated (PUFAs) and rare FAs, such as 22:5n–3 and two acetylenic FAs, 6a,9,12–18:3 and 6a,9,12,15–18:4 (dicranin). Acetylenic FAs were found in all examined species of the Bryales and Dicranales orders, dicranin being the predominant FA. The role of particular PUFAs in mosses and liverworts is discussed. Multivariate discriminant analysis (MDA) was performed to determine whether FAs can be used in the chemotaxonomy of bryophytes. Based on the MDA results, FA composition is related to the taxonomic status of species. Thus, several individual FAs were identified as chemotaxonomic markers at the level of bryophyte orders. These were 18:3n–3; 18:4n–3; 6a,9,12–18:3; 6a,9,12,15–18:4; 20:4n–3 and EPA in mosses and 16:3n–3; 16:2n–6; 18:2n–6; 18:3n–3 and EPA in liverworts. These findings indicate that further research into bryophyte FA profiles can shed light on phylogenetic relationships within this group of plants and the evolution of their metabolic pathways.
