In vitro activity of propolis: Synergism in combination with antibiotics against Staphylococcus spp.

Mastitis causes inflammation of the mammary gland and physical, chemical and bacteriological alterations in milk. The control of this disease deserves special attention within health programs of the dairy cattle industry. The aim of the present study was to assess the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of a commercial product (gentamicin + amoxicillin) indicated for the...

Studies on the physico-chemical and microbiological parameters associated with composting of brewer’s spent grains using different activators

Seven compost piles were formulated using brewer’s spent grains (BSG) as the bulk material amended with varied quantities of poultry droppings, soybean meal, cow dung and groundnut husks (activators). Composting was done through the static pile method in seven 30 × 25 cm containers. The process spanned 50 days during which temperature, pH, elemental profiles and microbial numbers were measured using standard...

Microbial degradation of 4-chloroaniline by a bacterial consortium

In this study, we have isolated four different species from effluent contaminated soil using a mixture of aniline and 4-chloroaniline (4CA) as principal carbon sources. The four species were identified as Pseudomonas stutzeri A, Comamonas testosterone B, Pseudomonas putida C and Stenotrophomonas maltophilia D. Growth studies on aniline and 4CA as single and mixed substrates demonstrated that the bacteria preferred to...

Impact of physico-chemical parameters on bacterial population in Mullaiperiyar River water-Theni district, Tamilnadu, India

The Mullaiperiyar River is one of the most imperative South Indian rivers. The present study was aimed to investigate the influence of physico-chemical factors in biological changes of Mullaiperiyar River water in Theni district. Water samples were collected from the upstream area (near the Dam - Lower camp, Kullapagoundanpatty, Karunakka muthanPatti), urban stretch area (Surlipatti, Uthamapalayam, Chinnamanur and...

Molecular identification of bifidobacteria from infant faeces

Bifidobacteria have been in the spotlight of scientific research due to their health promoting effects in humans. They play a significant role in controlling pH of the large intestine through liberation of lactic and acetic acid, thereby restricting the growth of many potential pathogens and putrefactive bacteria. This paper discusses the isolation and identification of bifidobacterial species from infant faeces by...

Microbial control of the exotic spiralling whitefly, Aleurodicus dispersus (Hemiptera: Aleyrodidae) on eggplant using entomopathogenic fungi

Biological control using entomopathogenic fungi is a promising alternative to chemical control. The entomopathogenic fungi, Beauveria bassiana (Balsamo) Vuillemin, Metarhizium anisopliae (Metschnikoff) Sorokin, Lecanicillium lecanii (Zimmerm.) Zare and Gams and Isaria fumosorosea (Wize) were tested for their efficacy in controlling the spiralling whitefly, Aleurodicus dispersus Russell (Hemiptera: Aleyrodidae) on...

Induction of defense response in Indian mustard against Alternaria blight through abiotic inducers

Soaking seed overnight and foliar spray with salicylic acid, indole acetic acid, metalaxyl, dipotassium hydrogen orthophosphate, hydrogen peroxide, calcium chloride and ferric chloride as inducers provided induced resistance in plant against Alternaria brassicae, resulting in a decline in the disease incidence after 10 days of pathogen inoculation. The minimum disease incidence (14%) was recorded from salicylic acid...

Effect of subsurface drip fertigation on growth, yield attributes and microbial population of banana cv. Rasthali

Field experiment was carried out during 2010-2011 at All India Coordinated Research Programme Water Management block, Agricultural College and Research Institute, Madurai. There were eleven treatments replicated three times in randomized block design using banana cv. Rasthali as a test crop. In recent years, fertigation a technique of application of both water and fertilizers via an irrigation system was shown to be...
