Selective macroalgae comprising green algae (Ulva lactuca), brown (Padina gymnosphora, Sargassam wightii, Turbinaria ornate) and red (Gracilaria corticata, Halimeda macrolopa, Halymenia dilatata, Gracilaria crassa) were collected from Gulf of Mannar, India. Taxonomic molecular identification affirmed the identity microalgal species. Free fatty acids Fatty Acid Methyl Ester (FAME) synthesis by t...

The main organic input for the elaboration of growing media is peat (Sphagnum spp.), due to its physical and chemical characteristics. However, mining this material creates a considerable impact in local ecosystems from which obtained, along with global because emission greenhouse gasses. Thus, sustainable materials that can replace, or reduce use peat, while maintaining improving attributes pl...

Lactuca indica (Compositae) is an edible wild vegetable, used as a folk medicine in anti-inflammatory, antibacterial, and other medications in Asia. This is the first scientific evaluation of the chemopreventive therapeutic properties of L. indica using five antioxidation assay systems. An extract from L. indica was found to possess significant free radical scavenging activity, effectively prot...

Traditionally, Lactuca sativa (lettuce) has been recommended for its hypnotic property. The present study was planned to investigate sleep-prolonging effect of this plant. The hydro-alcoholic extract (HAE) of lettuce and its water fraction (WF), ethyl acetate fraction (EAF), and n-butanol fraction (NBF) were administrated (IP) to mice 30 min before the pentobarbital injection. Moreover, both in...

The toxicities of three synthetic surfactants to the marine macroalga, Ulva lactuca, have been examined by monitoring chlorophyll a fluorescence quenching. The anionic surfactant, sodium dodecyl sulphate (SDS), exerted no measurable toxicity over the concentration range 0–10 mg L, while presence of the non-ionic surfactant, Triton X-100 (TX), elicited a small reduction in photochemical efficien...

A presença de compostos bioativos em frutas e hortaliças contribui para hábitos alimentares mais saudáveis ​​e maior qualidade. alface (Lactuca sativa L.) é a hortaliça folhosa aceitação no mercado consumidor, fonte vitaminas, minerais outros do metabolismo secundário das plantas. O objetivo deste estudo foi avaliar influência dos sistemas cultivo (orgânico, convencional hidropônico) Lactuca L....

A soilborne disease of lettuce, associated with necrosis and dieback, has been found with increasing frequency in California and Arizona over the last 10 years. An isometric virus, serologically related to Tomato bushy stunt virus (TBSV), was consistently isolated from lettuce plants with these disease symptoms. Back-inoculation to healthy lettuce plants and subsequent reisolation of the virus ...
