It is hypothesized that NDFO provides energetic benefits via a mixotrophic physiology in environments where cells encounter very low substrate concentrations, thereby minimizing cell encrustations, and results provide evidence that, under environmentally relevant concentrations of substrates, NDFO can enhance growth without the formation of growth-limiting cellencrustations.

These findings suggest that some species could be members of microbial communities influencing iron redox cycling in anoxic, freshwater sediments, and demonstrates that Fe(II) oxidation was microbially catalyzed rather than a result of abiotic oxidation by biogenic NO2−.

Overall, it is inferred that deep-sea sediments experiencing thermogenic hydrocarbon inputs harbor phylogenetically and functionally diverse communities potentially sustained through anaerobic hydrocarbon, acetate and hydrogen metabolism.
Museum fish specimens and molecular taxonomy: A comparative study on DNA extraction protocols and preservation techniques
- Anirban Chakraborty, M. Sakai, Y. Iwatsuki
- Biology
- 1 April 2006
The results show that mtDNA extraction, amplification and sequencing of conserved genes could be obtained successfully from frozen (−20°C) preserved specimens and also from ethanol- preserved specimens but not from any of the formalin (10%) fixed specimens (3–4 years).
Native polyubiquitin promoter of rice provides increased constitutive expression in stable transgenic rice plants

- 1 February 2012
For the first time, results showed increased expression of gusA gene in rice tissue when driven by the native Ubi1 promoter when compared to the use of corn Ubi 1 promoter, and indicated that the cis-regulatory elements present in the native promoter element might have been responsible for high expression.
An unedited 1.1 kb mitochondrial orfB gene transcript in the Wild Abortive Cytoplasmic Male Sterility (WA-CMS) system of Oryza sativa L. subsp. indica

- 2 March 2010
A new point of departure to dissect the mechanisms governing the CMS-WA system in rice has been identified, which can be applied to further harness the opportunities afforded by hybrid vigor in rice.

- 2015
The study has broadened the understanding related to differential biochemical composition of the rich sesame germplasms, thereby providing a useful groundwork for identifying potential targets and suitable cultivars for genetic engineering approaches to be undertaken in order to improve the nutritional quality of sesame oil, which in turn would be beneficial towards human health.
Genetic differentiation between two color morphs of Gerres erythrourus (Perciformes: Gerreidae) from the Indo-Pacific region
- Anirban Chakraborty, M. Venugopal, K. Hidaka, Y. Iwatsuki

- 25 May 2006
A portion of the mitochondrial 16S rRNA gene was compared between two color morphotypes of Gerres erythrourus obtained from Ryukyu Islands, Japan, and various areas of the Indo-Pacific, respectively, indicating that the two color Morphs represent two distinct species.
