Insights into effects of algae on decay and distribution of bacterial ...
Abstract The decay and distribution of bacterial pathogens in water is an important information for the health risk assessment to guide water safety management, and suspended algae might affect bacterial pathogens in water.
The importance of pathogenic Escherichia coli strains and emerging pathogens in drinking water-transmitted diseases is also briefly discussed. Microbiological water analysis is mainly based on the concept of fecal indicator bacteria.
Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal ...
In this section, we summarise the molecular mechanisms that underlie bacterial behaviour during algicidal activity, including how bacteria sense cues from algae , approach and adhere to algal cells, how collective (group) behaviours contribute to algicidal function, and the emerging mechanism of vesicle-mediated delivery of algicidal substances.
Algae and bacteria have co-occurred and coevolved in common habitats for hundreds of millions of years, fostering specific associations and interactions such as mutualism or antagonism. These interactions are shaped through exchanges of primary and secondary metabolites provided by one of the partners. Metabolites, such as N-sources or vitamins, can be beneficial to the partner and they may be ...
Algae rarely occur as solitary phototrophs in nature or engineering; instead, they are embedded in complex bacterial consortia that control their physiology, productivity and ecological performance. The phycosphere, a microscale niche rich in algal exudates, promotes extensive metabolic exchange and chemical signaling, defining these associations. Bacteria capitalize on the dissolved organic ...
Algae and bacteria together influence ecosystems as varied as deep seas to lichens and represent all conceivable modes of interactions — from mutualism to parasitism. Several studies have shown that algae and bacteria synergistically affect each other's physiology and metabolism, a classic case being algae -roseobacter interaction.

The current study gives a detailed insight into mutualistic collaboration of microalgae and bacteria, including the involvement of competitive interplay between bacteria. We provide experimental evidence that Gram-negative bacteria belonging to the ...
Learn about Harmful Algae , Cyanobacteria and Cyanotoxins Overview of Harmful Algae Algae are natural and important primary producers in aquatic ecosystems. Some species, under certain conditions can produce toxins that affect human health and the environment.
Algicidal Bacteria
The development of algicidal bacteria or compounds derived from bacteria for control of harmful algal blooms is reviewed with a focus on environmentally friendly or sustainable methods of application. Potential avenues for future research and further development and application of bacterial algicides for the control of algal blooms are presented.
Here, we explore by experiment and theory a realization of these interactions in which chemotactic bacteria respond to the oxygen produced by immotile green algae through photosynthesis.
