Summary: This article introduces a new method, far-red cyanobacteria identification (FRCI), based on 16S rRNA gene sequences to identify far-red light-utilizing cyanobacteria (FRLCyano). Experimental results demonstrate that FRCI can detect FRLCyano more sensitively than pigment analysis during far-red light enrichments and can also resolve their composition at the genus level. Additionally, the method is applied to published datasets and reveals potential FRLCyano in diverse environments.

Summary: Bacteria in lakes play important roles in biogeochemical cycles and ecosystem services. This study examined the distribution patterns of abundant and rare planktonic bacteria across 167 New Zealand lakes using 16S rRNA gene metabarcoding. The results showed that bacterial communities had a skewed distribution, with a few abundant species and many rare species. The abundance of local bacteria species was negatively correlated with the percentage of high productivity grassland in the catchment and positively correlated with altitude. Regionally rare bacteria species had a restricted distribution and were only found in a few lakes. Environmental processes played a larger role in structuring the regionally abundant community, while geographic distances were more important for regionally rare bacteria species.

Summary: Aquaculture facilities such as fishponds have a significant anthropogenic impact on freshwater ecosystems, with high fish biomass leading to increased nutrient load and potential effects on microbial communities and fish health. In an interconnected aquaculture system, natural seasonal cycles have a greater influence on the structure of aquatic bacterial communities compared to aquaculture-related factors. Recurring cyanobacterial blooms in response to different nutrient ratios, possibly influenced by fish feed input magnitude, were observed in the system.

Summary: This study reveals a broad ecological spectrum of bacterial taxa in stalactites, suggesting that bacterial transport into stalactites may be possible through water movement from the cave environment. The trapped bacteria support paleoecology, paleomicrobiology, and paleoclimate variations, and are associated with various environments such as water, soil, animals, and plants.

Summary: This study conducted a 10-week feeding experiment on 120 African catfish and analyzed the intestinal microbiota, finding that spirulina supplementation may lead to an increase in bacterial richness, but the overall microbial community structure was not affected.

Summary: The germplasm bank of economic algae serves as a biological insurance for the cultivation industry, but the red algal germplasm is easily contaminated by filamentous cyanobacteria, hampering its growth. This study utilized cytological observations, 16S rRNA gene analysis, and microscopy to investigate the contamination pattern. It was found that the filamentous cyanobacteria mainly originated from the red algal thallus or surrounding seawater.

Summary: The strains of Drouetiella species from a terrestrial biotope in the Arctic and Subarctic areas of European Russia were isolated and characterized using an integrative approach. The study showed the morphological plasticity of Drouetiella species and identified a new taxon. The analysis of 16S-23S ITS rRNA sequences revealed differences in length and nucleotide composition, affecting the hypothetical secondary structures of certain helices.

Summary: The blowfly species Lucilia sericata and Lucilia cuprina play roles as agricultural pests, in forensics, and in medicine. While L. sericata larvae are used in maggot debridement therapy, L. cuprina larvae are major initiators of sheep myiasis in certain regions. Bacterial DNA extraction and sequencing showed that digestive tracts and female salivary glands carried the most bacteria in both species, with genera Pseudomonas and Corynebacterium being highly represented. Further research could focus on key organs like spermathecae and salivary glands to understand the role of bacteria in the blowfly life cycle.

Summary: This study examined the effects of Cry1B protein on the growth and development of non-target natural enemies. The results showed that Cry1B protein had no significant impact on the health indicators of P. astrigera, but it did reduce the number of symbiotic bacteria species and species diversity. The effects of Cry1B protein on symbiotic bacteria varied by growth and development stage and sex.

Summary: Fluorine and its compounds from industrial production and coal combustion can cause contamination of air, water, and soil, posing a threat to public health through accumulation in animals, plants, and humans via food chain. Exposure to fluoride resulted in damaged intestinal structure and altered gut microbial composition in ducks.

Summary: This study examined the microbial population and presence of cyanobacterial toxins in commercially available spirulina products. Potentially pathogenic bacteria were detected in the products, along with microcystin toxins at levels that could exceed the recommended daily limits. The study highlights microbiological safety issues associated with commercial spirulina products produced in open ponds.

Summary: This review focuses on the diversity, environmental adaptations, and ecotypes of Antarctic cyanobacteria. Despite being well-studied, there are still substantial drawbacks such as lack of consensus on diversity evaluation, limited knowledge on biofilm systems, and unresolved questions on endemism in prokaryotes within the Antarctic cyanobacteria biosphere.

Summary: Several strains of unicellular cyanobacteria originally identified as Synechocystis sp. from St. Petersburg State University culture collection have been reclassified into a new genus Altericista, proposing three new species. Altericista, morphologically similar to Synechocysis, is distinct in its ability to produce accessory chlorophylls d and f in cultures exposed to far-red light, showing ecological, biochemical, and physiological differences from Synechocystis.
