ABSTRACT- The production of greenhouse sweet pepper is increasing because of the consumer demand for sweet pepper year around. In this study, physiological characteristics of sweet pepper were evaluated in a greenhouse under different levels of arbascular mycorrhizal fungus, Glomus intraradices, (AMF) and various levels of amino acid (AA). Treatments included no AMF as a control (AMF1), 1000 sp...

The present feature describes for the first time the application of spores from Aspergillus sp. IMPMS7 to break out crude oil-in-water emulsions (O/W). The fungal spores were isolated from marine sediments polluted with petroleum hydrocarbons. The spores exhibited the ability to destabilize different O/W emulsions prepared with medium, heavy or extra-heavy Mexican crude oils with specific gravi...

Clostridium difficile is a Gram-positive, sporogenic and anaerobic bacterium that causes a potentially fatal colitis. C. difficile enters the body as dormant spores that germinate in the colon to form vegetative cells that secrete toxins and cause the symptoms of infection. During transit through the intestine, some vegetative cells transform into spores, which are more resistant to killing by ...

abstract polymyxa betae is an obligate parasite and has a worldwide distribution. this fungus is a soil-borne root endoparasite in some plant families such as portulaceae, chenopodiaceae and amaranthaceae. this fungus is the vector of many plant viruses such as beet necrotic yellow vein virus (bnyvv) which causes the disease known as rhizomania. bnyvv is the most economical important viral dise...

Melanins are universal biopolymers, the main biological function of which is to protect living organisms from adverse factors. Interest in these dark pigments arises due prospects for their use medicine, cosmeceuticals, bioremediation, bioelectronics, and other fields. In this work, a complex scheme was developed isolate melanins lichen Leptogium furfuraceum (Harm.), symbiotic extremophilic org...

Two peptidoglycan-lytic enzyme activities were isolated from spores of Bacillus megaterium KM. Surface-bound lytic enzyme was extracted from dormant spores and hydrolysed a variety of peptidoglycan substrates including isolated spore cortex, but did not cause refractility changes in permeabilized spores. Germination-specific lytic enzyme activity appeared early in germination and had minimal ac...
