Temporal variation (June and October 2012) in bacterial and phytoplankton communities of Kongsfjorden was studied using 16S rRNA gene clone libraries and marker pigments respectively. Proteobacteria was the dominant phyla in Kongsfjorden with Gammaproteobacteria (42%) and Alphaproteobacteria (84%) dominating in June and October, respectively. Retrieval of sequences affiliated to Verrucomicrobia, Gammaproteobacteria and Bacteroidetes in June corresponded with high autotrophic biomass (Chl α, 33 ng l–1) whereas abundance of SAR 11 coincided with decrease in the intensity of autotrophic biomass (Chl α, 24 ng l–1) in October. Thus, the distribution of bacterioplankton community varied with change in phytoplankton composition indicating a significant coupling between these two groups in the fjord water.Keywords

Chilli, an essential condiment worldwide, is generally cultivated in paddy fields and can be infected by fungal pathogens, thus hampering its yield. Due to increasing soil salinization, the efficacy of many biocontrol agents is poor in the fields. In this study, bacteria (about 196) isolated from the Goan salt pans in India were screened for their antifungal activity against Fusarium oxysporum, Fusarium pallidoroseum, Rhizoctonia solani and Pythium aphanidermatum. Halotolerant isolates of Bacillus tequilensis, Bacillus subtilis subsp. inaquosorum, Bacillus cabrialesii, Bacillus licheniformis, Bacillus paralicheniformis and Brevibacterium antiquum could grow under a wide range of pH, temperature and NaCl concentrations, and also displayed plant growth-promoting attributesKeywords
