“…Seven cyanobacterial strains, namely Oscillatoria limosa, Arthrospira platensis, Phormidium laminosum, Phormidium sp, Scytonema javanicum, Nostoc punctiforme and Phormidium angustissimum were identified using conventional morphological characters [12] and used as subjects for ATR FTIR spectroscopy. The strains used and their origin are summarized in Table 1.…”

A method was developed whereby high quality FTIR spectra could be rapidly acquired from soil-borne filamentous cyanobacteria using ATR FTIR spectroscopy. Spectra of all strains displayed bands typical of those previously reported for microalgae and water-borne cyanobacteria, with each strain having a unique spectral profile. Most variation between strains occurred in the C-O stretching and the amide regions. Soft Independent Modelling by Class Analogy (SIMCA) was used to classify the strains with an accuracy of better than 93%, with best classification results using the spectral region from 1800-950 cm(-1). Despite this spectral region undergoing substantial changes, particularly in amide and C-O stretching bands, as cultures progressed through the early-, mid- to late-exponential growth phases, classification accuracy was still good (approximately 80%) with data from all growth phases combined. These results indicate that ATR/FTIR spectroscopy combined with chemometric classification methods constitute a rapid, reproducible, and potentially automated approach to classifying soil-borne filamentous cyanobacteria.

“…Additionally, the distribution of various species of Anabaena was also undertaken for a better understanding of their proliferation vis a vis rice soil types. Desikachary [4] stressed that cultural studies are essential to understand the behavioural pattern of bluegreen algae. According to Stulp [34], incubation under different light and temperature conditions hardly affects the taxonomically important characters such as shape of vegetative cell, heterocyst and akinetes, posi- tion of akinetes.…”

The genus Anabaena is one of the commonly observed genera in the rice fields in South-east Asia. Diversity analyses of a set of 70 Anabaena strains (including 67 strains isolated from diverse rice agro ecologies of India, and three International Reference/Type strains), was carried out using morphological and molecular datasets. The pattern of growth in liquid and solid medium and microscopic observations revealed tremendous diversity in the Anabaena germplasm analysed. The species wise distribution in different soil types and soil pH revealed that Anabaena iyengarii was present at pH ranging from 5.5-8.5 and all the species of Anabaena except A. oscillarioides were present in alluvium soils. Molecular profiling using primers based on HipTG, STRR(mod) and STRR1A sequences generated specific fingerprints for individual isolates. STRR1A was observed to be the most informative and useful for differentiating the isolates. Analyses of a combined dataset, including both morphological and molecular data, proved highly effective in discerning the genetic relationships among the 70 Anabaena strains. The present study provided useful information for the development of a comprehensive database based on the distribution of Anabaena strains in diverse agro ecologies of India and identified useful primers for PCR based differentiation of isolates.

“…Cyanobacteria play an important role in the nitrogen cycle. They are one of very few groups of organisms that can convert inert atmospheric nitrogen into an organic form, such as nitrate or ammonia and also they provide oxygen as a by-product of photosynthesis [13], a food source for other organisms such as zooplankton, insects and snails, and in the case of larger filamentous algae, a habitat for small animals [14]. The most common toxic Cyanobacteria in fresh water are Microcystis spp., Cylindrospermopsis raciborskii, Planktothrix (syn.…”

Cyanobacterial species (blue-green algae) constitute the major part of the phytoplanktonic biomass during the summer in freshwater ponds. The aim of the research work was to study the biodiversity of cyanobacteria among 20 different freshwater ponds of the Pudukkottai district of Tamil Nadu, India. The morphological identification of cyanobacterial species was carried out using a trinocular microscope. The results showed that the maximum number of cyanobacterial species belonged to Oscillatoriaceae, Nostocaceae, Microcystaceae, Scenedesmaceae, and Desmidiaceae families. Among 25 different families of Cyanobacteria about 42 distinct species were identified. These results showed that the freshwater ponds of the Pudukkottai district have an abundance of cyanobacteria species.
