Exploring the Interactions Between Algae and Bacteria

Abstract

Humans have used algae for hundreds of years to make various products viz. agar, fertilizer, food, and pigments. Algae are also used in bioremediation to clean up polluted water and as essential laboratory tools in genomics, proteomics, and other research applications such as environmental warnings. Several special features of algae, including the oxygenic photosynthesis, higher yield in biomass, growth on the non-arable lands, their survival in a wide range of water supplies (contaminated or filtered waters), the production of necessary byproducts and biofuels, the enhancement of soil productivity, and the greenhouse gas emissions, etc. altogether rendered them as vital bio-resources in the sustainable development. Algae and bacteria have been assumed to coexist from the early stages of the development of the earth, and a wide variety of interactions were observed between them which have influenced the ecosystems ranging from the oceans to the lichens. Research has shown that bacteria and algae interact synergistically, especially roseobacter-algae interactions being the most common. These interactions are common to all ecosystems and characterize their primary efficiency. The commercialization of algae for industrial purposes, an important field, is also influenced by this interaction which frequently results in bacterial infections among the consumers. However, the recent findings have revealed that the bacteria improve algal growth and support flocculation which are very crucial in algal biotechnology. Some of the most exciting advancements in the area of algal biotic interactions and potential difficulties were reviewed in this article. Information gleaned in this study would provide a firm foundation for launching more contemporaneous research efforts in understanding and utilizing the algal species in biotechnology industries and medical sectors.

Revealing the Bacterial Quorum-Sensing Effect on the Biofilm Formation of Diatom Cylindrotheca sp. Using Multimodal Imaging

“…The latter are the dominant components in the diatom-biofilm [ 6 , 7 ]. In addition, earlier studies reported that the growth of algae depended on bacteria or bacterial enzymes, and algae synthesized necessary substances such as vitamin B12 via these enzymes [ 8 , 9 ]. Although the importance and the relevance of bacteria for diatoms have been recognized, the interactions between bacteria and diatoms are still poorly understood, especially in fouling biofilms.…”

Effect of Environmental Factors on Nitrite Nitrogen Absorption in Microalgae–Bacteria Consortia of Oocystis borgei and Rhodopseudomonas palustris

“…Both O. borgei and photosynthetic bacteria are common dominant species in shrimp culture ponds, and by artificially constructing the microalgae-bacteria consortia in the culture pond, the biological community in culture ponds can be kept relatively stable [42], and the purification capacity of the microalgae-bacteria consortia for the water body can be optimized by adjusting the composition ratio of algal-bacteria and various environmental factors. Studies have shown that both photosynthetic bacteria and O. borgei have better efficiency for nitrite removal [40,43].…”

Next-Generation Probiotics - The Future of Biotherapeutics

“…The capsular polysaccharide B. fragilis (PSA), which can modulate microbiota-host interactions, plays the most important function in this. PSA increases T-cell anti-inflammatory memory thanks to zwitterionic motifs, which lowers systemic inflammation symptoms (Lukiw, 2016;Tan et al, 2020;Nowruzi et al, 2022). Because of their potential to reduce pathogen-induced inflammation and cure autism spectrum disorders, as well as their ability to reduce Vibrio infections and antibiotic-induced diarrhea, B. fragilis strains are regarded as promising next-generation probiotics (Zhang et al, 2018).…”
