In this paper, we present a selective and differential medium, termed Vibrio alginolyticus (VAL) agar, developed for the isolation and identification of V. alginolyticus. The presence of bile salts, high salinity and high incubation temperature allows the selective growth of moderately halophilic Vibrio species. Differentiation of bacteria is achieved by identifying species capable of sucrose f...

The high affinity K⁺ transporter 1;4 (HKT1;4) in rice (Oryza sativa), which shows Na⁺ selective transport with little K⁺ transport activity, has been suggested to be involved in reducing Na in leaves and stems under salt stress. However, detailed physiological roles of OsHKT1;4 remain unknown. Here, we have characterized a transfer DNA (T-DNA) insertion mutant line of rice, which overexpresses ...

A membrane filter procedure has been developed for the rapid quantitation of C. perfringens in the aquatic environment. Background growth is inhibited by the use of D-cycloserine, polymyxin B sulfate, and incubation at 45 degrees C. Differential characteristics include the fermentation of sucrose, production of acid phosphatase, and the absence of beta-D-glucosidase activity. The medium is prep...

Purpose: The purpose of the study is identify and characterizes different species of dermatophytes from 300 clinically defined cases of ring worm infections. Based upon their morphological features studied by microscopic, culture and biochemical techniques and comparison of Sabouraud dextrose agar (SDA) and Dermatophyte test medium (DTM) for the primary isolation of dermatophytes from the clini...

A new in vitro experimental system was developed to study the morphogenesis of discrete regions of a single extraradical mycelium of the arbuscular mycorrhizal (AM) fungus Glomus intraradices, growing simultaneously in six different agar-based media. The media were (i) unamended water agar (WA), (ii) WA+PO(4)(3-) (PO(4)(3-)), (iii) WA+NO(3)(-) (NO(3)(-)), (iv) WA+NH(4)(+) (NH(4)(+)), (v) WA+NH(...

Three simple new visible spectrophotometric methods has been developed for determination of Losartan potassium and Omeprazole, in single component pharmaceutical dosage forms. The methods were based on the formation of ion-pair complexes of the drug with dye Bromocresol purple(BCP) and Bromophenol blue(BPB), in acidic buffer solutions followed by their extraction in chloroform. Experiments were...
