All bacteria have the 16S rRNA gene, but the exact DNA sequence is unique to each species. So it is used as a sort of molecular fingerprint. When scientists isolate a microbe, they sequence its 16S rRNA gene and compare it to known sequences in a database. If they find a match, they can identify the species.

What is the microbial diversity of coffee beans?
The microbial diversity of coffee beans in wet processing is smaller compared with that in dry processing, because the fermentation time is shorter (up to 48 h) and there is a more rapid pH decline from 6 to 4.3. This microbiota comprises few bacterial and yeast species. There is no report of filamentous fungi involved in wet fermentation. The mucilage adhered to beans is the substrate used by bacteria and yeast during fermentation. Higher microbial diversity in washed coffee fruits could be observed using molecular identification techniques that allow the detection of cultivable and uncultivable microorganisms.
What are the most common microbial groups in freshwater ecosystems?
Both free-living and endosymbionts have been found. Microalgae, the other dominant microbial group in freshwater, consists of prokaryotic or eukaryotic photosynthetic microorganisms that can grow rapidly and live in harsh conditions due to their unicellular or simple multicellular structure. The freshwater algae having microscopic appearance includes: green algae (Chlorophyta), Euglenoids, Xanthophyta, Dinoflagellates, Cryptophyta, Chrysophyta, Diatoms, Bacillariophyta, Rhodophyta, and Brown algae. The microalgae are the most promising sources of natural carotenoids and other compounds, such as fats, polyunsaturated fatty acids, oil, natural dyes, sugars, pigments, antioxidants, high-value bioactive compounds, and other fine chemicals. Cyanobacteria are basically microscopic, although large colonies or mats are quite conspicuous. Microbial mats are considered to be natural ecosystems that produce gases like CO2, CH 4, H 2, thereby promoting the potent use of gases, primarily produced by Cyanobacteria as biofuels. Their possible use in aquaculture; food; feed; fuel; fertilizer; colorant; production of various secondary metabolites including vitamins, toxins, enzymes, pharmaceuticals, pharmacological probes; and pollution abatement has given rise to the branch of algal biotechnology. This chapter highlights the commercial applications of Cyanobacteria as well as microalgae, discussing the challenges that need to be addressed to make cyanobacterial industrial biotechnology more feasible in near future.
