The development of a particular ecosystem requires water for sustainability of living organisms. Different organic and inorganic components are dissolved in water, as it is universal solvent. The optimum level of different constituents is responsible to maintain respective quality for the suitable growth and development of plants, animals and micro-organisms. The physico-chemical parameters of water samples collected in the year 2018-2019 from Jayakwadi dam were analysed. To understand these parameters is important, as the Jaykwadi dam water is essential for drinking, irrigation and industrial concern of Marathwada region. Therefore, in this paper different physico-chemical parameters viz. Temperature, pH, DO, BOD, Hardness, alkalinity, TDS, turbidity, Chlorides, Phosphates, chlorine, nitrates etc. are studied.

We have recently discovered a novel dimorphic yeast Aureobasidium tremulum sp.nov. The species name tremulum indicates its trembling movement. With keen microscopic observations and various experimentation, we concluded that the movement is of two types, trembling movement, and actual displacement. The movement is because of two reasons; 1. Due to the dynamic movement of intracellular lipid granules, and; 2. Due to the movement of an intracellular bacterial population which is present as an endosymbiont. The mechanism of displacement has been hypothesized. The presence of both lipid granules and bacteria has been confirmed using microscopic analysis (Bright field, Phase contrast, confocal, Cryo-SEM, and HR-TEM). The bacterial presence was confirmed using whole-genome metagenomic analysis. Endosymbiotic bacteria have also been isolated and identified by 16s rRNA gene sequencing. Interestingly, some of them possibly are novel species. Also, the whole genome of A.tremulum has been announced. We also report on, restriction of the mode of bacterial mycophagy in presence of an antibiotic.
