Control of psychrophilic microbiota in shrimp (Litopenaeus vannamei) by Lactobacillus reuteri

As an alternative to traditional methods for controlling microorganisms in food, bioprotection using lactic acid bacteria is promising. Lactobacillus reuteri exhibits an ability to produce reuterin, an antimicrobial substance presenting effects against Gram-positive and Gram-negative bacteria, as well as molds, yeasts and protozoa. In the present study, the activity of L. reuteri culture and extract over psychrophilic...

Antibacterial activity of Andrographis paniculata Nees against selective human pathogens

The present study was conducted to investigate the antibacterial effect of Andrographis paniculata against selective human pathogens. The plant parts of A. paniculata such as leaf, stem and root were studied for its antibacterial activity. Different solvents were used to extract the active components from the plant parts. The antibacterial activity was studied against selective human pathogens viz., Staphylococcus sp.,...

Evaluation of rice landraces against rice root-knot nematode, Meloidogyne graminicola

Of late, rice root-knot nematode Meloidogyne graminicola has become a serious menace in all type of rice situations in India. A field study was under taken during kharif-2013 to evaluate 135 landraces (local cultivars) collected and maintained at Organic Farming Research centre of ZAHRS, Navile, Shimoga against Meloidogyne graminicola. The result reveals that the varieties show varying degrees of responses. Out of 135...

Performance evaluation of laboratory professionals on tuberculosis microscopy at Hawassa Town, Southern Ethiopia

Microscopic diagnosis of Ziehl-Neelsen stained sputum by microscopists has remained the best routine laboratory method for the diagnosis of tuberculosis (TB). However, detection and identification of TB require skilled laboratory personnel. The aim of the study was to assess the performance of laboratory professionals in detecting TB bacilli at Hawassa town health institutions. A cross-sectional study design was...

Biosynthesis of indole-3-acetic acid by plant growth promoting rhizobacteria, Klebsiella pneumonia, Bacillus amyloliquefaciens and Bacillus subtilis

Indole-3-acetic acid biosynthetic activity of Klebsiella pneumonia, strain MR-M1, Bacillus amyloliquefaciens strain MR-AI, four Bacillus sp. strain MR-SP, RR-R2, WR-W2 and MR-Z1 were investigated. Here, the authors demonstrated the effect of carbon sources, amino acids, vitamins and abiotic stress on the indole-3-acetic acid (IAA) production level under in vitro condition by the six strains. The culture medium was...

Assessment of phenol biodegradation capacity of indigenous bacteria isolated from sewage treatment plant

Among different xenobiotics, phenol is a man made as well as a naturally occurring aromatic compound and an important intermediate in the biodegradation of natural and industrial aromatic compounds. The investigation was undertaken to isolate, characterize and exploit phenol degrading bacteria from sewage treatment plant (STP) (artificial ecosystem having diverse group of bacteria which are adapted to different aromatic...

Resistance of heavy metals on some pathogenic bacterial species

Microorganisms are known to be highly sensitive to the presence of heavy metals and some of the early attempts to control microorganisms had used copper sulphate as plant fungicide and mercury salts for some infectious diseases; but, the order of toxicity varies among different organisms and in general mercury and silver are more toxic than manganese and zinc. It has been seen that responses of organisms to heavy metal...
