Soybean homeobox gene GmSBH1 has previously been proven to be involved in response to high temperature and humidity (HTH) stress. To investigate its expression patterns and active cis-elements, a 2040-bp 5’-upstream genomic DNA fragment of GmSBH1, named GmSBH1P, was isolated by PCR walking and characterized. Sequence analysis revealed that the fragment contains a series of cis-acting elements related to stress responses.

Yeast infections are often connected with formation of biofilms that are extremely difficult to eradicate. An excellent model system for deciphering multifactorial determinants of yeast biofilm development is the colony biofilm, composed of surface (“aerial”) and invasive (“root”) cells. While surface cells have been partially analyzed before, we know little about invasive root cells. In particular, information on the metabolic, chemical and morphogenetic properties of invasive versus surface cells is lacking.

β-D-glucans (beta-Glucan), a water-soluble polysaccharide with diversity physiological activities for applications in food and pharmaceutical industries. Methods: In this paper, we report the use of ionic liquid 1-butyl-3-methyl-imidazolium chloride [BMIM]Cl on the extraction and isolation of β-glucan from baker's yeast Saccharomyces cerevisiae. The β-D-glucans precipitated by adding water into the solution and obtained by filtration or centrifugation were pure, cleaned, and free of cell membranes.

Amylase producing thermophilic bacterial strain was isolated from Jeori hot water spring, Rampur Bushahr of Shimla district of Himachal Pradesh, India and identified as Bacillus thuringiensis J2 using 16S rRNA gene sequencing and deposited in NCBI gene bank vide accession number |KY990713|. Medium components and process parameters were optimized with respect to substrate concentration, carbon sources, nitrogen sources, incubation period, pH and temperature for an enhanced amylase production.

This study analyzed Baker‟s yeast efficiency based upon its ability of growth on various agro-industrial wastes that act as the carbon source with an addition of nitrogen supplement at various growth parameters. Various locally available carbon sources including molasses, fruit bagasse juice, sugarcane bagasse juice and whey were used with inorganic as well as organic supplementation of corn steep liquor at a concentration of 50g/L. Increased productivity in case of the lab isolate was observed upon the use of organic supplementation @16.16%.

Lipases are secreted by many fungi, yeasts and bacteria. The suitable habitat to isolate lipase producing microorganisms is the oil contaminated sites. In Ujjain a very famous „Navgrah-Shani‟ Temple situated at the Triveni Ghat of Kshipra river, where devotees from all over India come and worship the lord and it is an unique oily habitat for isolation of lipase producing microorganisms. The present study was aimed to isolate, screen and identify the lipase producing fungi from the oil contaminated soil.

In nature, there exist a wide variety of microbes that can be of any economical importance to humans. A specialized group of microorganisms includes pigmented yeasts. They are yeasts that develop colored pigment as their secondary metabolites. In this study, pigmented yeasts were isolated from different sample (soil, leaves, fruits, coconut, and air) on Sabouraud’s agar. Four strains were selected that showed pigmentation. Various morphological and biochemical tests were performed for identification of the strains.

Fungal bloodstream infections (BSIs) are severe diseases that lengthen hospital stay, have elevated morbidity and mortality and increase medical care costs. Their incidence has recently increased, likely due to an increase in the number of susceptible hosts. The main aim of this study to characterization of candida isolated from blood from patient admitted in ICU. Our Objectives was to speciate candida isolated from the clinical sample & to do susceptibility testing of candida isolates using VITEK 2.

Maize Post flowering stalk rot causing caused by Fusarium verticillioides is major disease and causing yield loss up to 34 per cent. Different liquid media supporting the growth of the different isolates of fungus was observed. Among the eight-liquid media tested for the dry mycelial weight and sporulation of six isolates of Fusarium stalk rot pathogen (F. verticillioides), Isolate FV-3 yielded highest dry mycelial weight of 787.66mg, followed by FV-2 (647.66mg), FV1(581.00mg), FV-5 (451.00mg), FV-6(421.00mg) and FV7(277.66mg) in Takahashii’s broth.

Microorganisms produce certain commercially important secondary metabolites like antibiotics, carotenoid pigments, toxins and so on, some of which are of commercial importance. Carotenoid is a group of pigment and its production is a natural phenomenon in case of certain microorganisms. Yeast is a unicellular eukaryotic organism occurring in soil, air, feed and fodder of dairy farm environment. Among yeast, Rhodotorula sp. produces both extra and intracellular carotenoid pigments.

Phytase activity of bacteria, yeasts and moulds isolated from different ecosystems have been identified and studied by several researchers. The present study focused on isolation and identification of phytate solubilizing yeasts associated with freshly soaked cereals, pulses, condiments and oilseeds. Isolation on MRS-Calcium phytate at pH 6.2 ±0.2 resulted in a high diversity of microorganisms developing clear zones of phytate hydrolysis. Microscopic study revealed identification of three groups of phytate solubilizing organisms (viz.
