Based on their salt requirement, halophiles are categorized into different categories; 1. Slight, 2. Moderate, 3. Extreme. Moderate halophiles were isolated from Jamnagar Vadinar Bandar area. Total 16 isolates were obtained on N-agar plates containing various salt concentrations. These organisms were exploited for various hydrolytic enzyme activity i.e.; amylase, lipase, caseinase etc. Among 16 isolates, 9 were amylase positive, 12 were lipase positive, 13 were caseinase positive. Identification of these isolates was on the basis of morphology, physiology, biochemical activity. Further research on purification of one of these enzymes is in progress.

Presently according to the World Health Organization, there are a reported 79 million cases worldwide, including over ~1.3 million deaths, since its discovery and outbreak in China, in December 2019. This is the third pandemic within 18 years by Coronaviruses, which are members of the family Coronaviridae. The first being severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002 followed by the Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012. The aim of this review article is to provide amalgamated information about the pandemic by elaborating on the history and the origin of Coronavirus. Furthermore, we have discussed transmission, symptoms, virion properties and diagnostics of COVID-19 available till date.

Abstract: Rhizobacteria possessing multiple plant growth promoting activities. Halotolerant rhizobacteria were isolated from the groundnut soil sample with salinity 0.7mS/cm in Jodiya region of saurashtra. 48 bacterial isolates were obtained among which 45 isolates showed halotolerancy upto 12% NaCl concentration and different tests were performed to find plant growth promoting traits at 2% NaCl concentration. like NITROGEN FIXATION by bacteria in which all the bacteria has shown us that capacity. By performing the PHOSPHATE SOLUBILIZING TEST 24 isolates were positive. AMMONIA TEST and in IAA PRODUCTION TEST all isolates had given positive results and the maximum indole production was 62.18µg/ml. And in ANTIFUNGAL TEST 4 isolates had given positive result. Further several qualitative enzymatic test are performed like protease, catalase, amylase, cellulase, lipase. After that biochemical tests like MR test, VP test, H2S production test, H2O2 test, nitrate reduction test, TSI agar test, urea hydrolysis, citrate utilization test were performed.

The present study focuses on analyzing the role of halotolerant rhizospheric bacteria isolated from groundnut plant for enhancing the plant growth under salinity stress. A total of 32 isolates were isolated from rhizospheric soils from Dholara and Junagadh, Saurashtra Region of Gujarat (India). All the isolates showed salt tolerance up to 6% sodium chloride and were screened in vitro for the plant growth promoting traits. Only D3 isolate displayed all PGP activities positive and was selected for further analysis. A substantial increase in all the growth parameters was recorded with PGPR D3 in salt stress conditions using autoclave and non-autoclaved soil. The plant showed a significant increase in root length, shoot length, fresh weight, dry weight, number of leaves and biochemical parameters(Chl a,b) in presence of PGPR D3 under salt stress (100mM). Hence D3 can be used as an alternative to chemical fertilizer and use for the enhancement of plant growth under salt stress.
