Abstract:

A Gram-negative, rod-shaped, urea-dissolving and non-spore-forming bacterium, designated strain NiVa 51T, was isolated from water of the River Torsa in Hasimara, Jalpaiguri district, West Bengal, India. On the basis of 16S rRNA gene sequence similarity, strain NiVa 51T was shown to belong to the γ-Proteobacteria and to be related to Serratia marcescens subsp. sakuensis (98·35 %) and S. marcescens subsp. marcescens (98·30 %); however, strain NiVa 51T exhibited only 43·7 % similarity to S. marcescens by DNA–DNA hybridization.

Background and Objectives: Serratia is a gram-negative bacterium. The pigmentation property of Serratia Marcescens is used as a marker of dust particles in the environment and in the hospital. Today biopigments are also widely used in the manufacture and production of pharmaceutical products. Prodigiosin is a promising drug due to its reported properties of antifungal immunosuppressive and anti-proliferative activities. In the present study, cloning of pig gene- isolated from Serratia Marcescens in Ecoli XL1blue was performed. Subjects and Methods 60 Samples were taken from clinical sources of

Abstract:

ABSTRACT Serratia marcescens culture filtrates have been reported to be cytotoxic to mammalian cells. Using biochemical and genetic approaches, we have identified a major source of this cytotoxic activity. Both heat and protease treatments abrogated the cytotoxicity of S. marcescens culture filtrates towards HeLa cells, suggesting the involvement of one or more protein factors. A screen for in vitro cytotoxic activity revealed that S. marcescens mutant strains that are deficient in production of a 56-kDa metalloprotease are significantly less cytotoxic to mammalian cells.

Abstract:

A serious vine decline of cucurbits known as cucurbit yellow vine disease (CYVD) is caused by rod-shaped bacteria that colonize the phloem elements. Sequence analysis of a CYVD-specific polymerase chain reaction (PCR)-amplified 16S rDNA product showed the microbe to be a γ-proteobacterium related to the genus Serratia. To identify and characterize the bacteria, one strain each from watermelon and zucchini and several noncucurbit-derived reference strains were subjected to sequence analysis and biological function assays.

The results of standard biochemical probes supported the findings of the electron microscopy studies, suggesting that these antimicrobial peptides have different mechanisms of action.

One such pest is the rice stem borer (Scirpophaga innotata), which infests rice stems and poses a significant threat. To combat these pests, various microbial agents have been developed for effective pest control. Among these, the endophytic microbe in biological plant protection plays a key role in the program of sustainable pest management.

When mutated, both rssA and rssB mutants showed precocious swarming phenotypes on LB swarming agar, whereby swarming not only occurred at 37°C but also initiated on a surface of higher agar concentration and more rapidly than did the parent strain at 30°C. In this study, we further show that the predicted sensor kinase RssA and the response regulator RssB bear characteristics of components of the phosphorelay signaling
