The success of invasive species can be measured by invasiveness, which depicts intrinsic characteristics that enable them to thrive in new environments. In seaweeds, for example, the persistence multiple overlapping cohorts throughout year plays a key role increasing plant cover and exerting unrelenting pressure on invaded areas. marine brown macroalgae Rugulopteryx okamurae has recently established abundant populations Mediterranean Sea Atlantic Ocean, negatively affecting both biodiversity socioeconomic factors unprecedently aggressive behaviour. objective study is understand invasiveness R. through its popu lation dynamics. For this, year-round was conducted protected habitat Posidonia oceanica southern Spain, revealing uses alternating mechanisms population maintenance. It achieves high density young individuals late summer autumn, peaking at 3285 per square metre. spring early summer, shifts towards fewer – but larger individuals, with densities dropping 888 metre biomass reaching peak 170 g dry weight (DW) Six were identified Gaussian curves. They persisted year, they not related environmental factors, indicates adaptive physiological sustain dense monospecific populations. Additionally, association between different morphotypes suggests phenotypic plasticity enables introduced These findings provide valuable insights into biological traits underpinning P. meadows, temporal windows driven mechanisms. This knowledge crucial developing effective conservation management strategies aimed mitigating impact this species.

Valorization of Algal Biomass to Produce Microbial Polyhydroxyalkanoates: Recent Updates, Challenges, and Perspectives

Polymers, Год журнала: 2024, Номер 16(15), С. 2227 - 2227

Biopolymers are highly desirable alternatives to petrochemical-based plastics owing their biodegradable nature. The production of bioplastics, such as polyhydroxyalkanoates (PHAs), has been widely reported using various bacterial cultures with substrates ranging from pure biowaste-derived sugars. However, large-scale and economic feasibility major limiting factors. Now, algal biomass for PHA offers a potential solution these challenges significant environmental benefit. Algae, unique ability utilize carbon dioxide greenhouse gas (GHG) wastewater feed growth, can produce value-added products in the process and, thereby, play crucial role promoting sustainability. sugar recovery efficiency is variable depending on pretreatment procedures due inherent compositional variability among cell walls. Additionally, yields, composition, properties synthesized vary significantly microbial producers algal-derived Therefore, microalgal pretreatments synthesis copolymers still require considerable investigation develop an efficient commercial-scale process. This review provides overview discusses strategies enhance its properties, focusing managing GHGs sustainable future.
