Aliphatic hydrocarbons are highly appealing targets for advanced cellulosic biofuels, as they are already predominant components of petroleum-based gasoline and diesel fuels. We have studied alkene biosynthesis in Micrococcus luteus ATCC 4698, a close relative of Sarcina lutea (now Kocuria rhizophila), which 4 decades ago was reported to biosynthesize iso- and anteiso-branched, long-chain alken...

Mycobacterium tuberculosis possesses five genes with significant homology to the resuscitation-promoting factor (Rpf) of Micrococcus luteus. The M. luteus Rpf is a secreted approximately 16-kDa protein which restores active growth to cultures of M. luteus rendered dormant by prolonged incubation in stationary phase. More recently, the Rpf-like proteins of M. tuberculosis have been shown to stim...

El ensayo se realizó en el mes de marzo del 2021 Laboratorio Continental Puno – IMARPE, con la finalidad determinar efecto uso microalga Chlorella vulgaris como alimento al inicio ontogenia Orestias luteus, 1600 larvas mantenidas dos acuarios 45 L. Un acuario (agua verde), y otro sin clara). Se reflejan que durante los primeros 7 días las alimentadas microalgas presentaron mayor supervivencia d...

Assay organisms Saccharomyces cerevisiae and Sarcina lutea, when suspended in a weak buffer and stored at refrigerator temperatures, are stable for 1 year or more.

So far, the antibacterial activity of some organic and inorganic compounds has been studied. Barium zirconate titanate [Ba(ZrxTi₁-x)O₃] (x = 0.05) nanoparticle is an example of inorganic materials. In vitro studies have provided evidence for the antibacterial activity of this nanoparticle. In the current study, the nano-powder was synthesized by sol-gel method. X-ray diffraction showed that the...

Testing of lupine varieties for alkaloids was performed in the period 2006-2010 at the Voke Branch of the Lithuanian Institute of Agriculture in the course of a competitive trial of feeding lupine (Lupinus sp.). Samples of feeding yellow lupine (Lupinus luteus L.) varieties as well as narrow-leaved lupine (Lupinus angustifolius L.) were used. The alkaloid concentration was assessed in the perio...

An w protein capable of a concerted breaking and rejoining of DNA backbone bonds has been purified from Micrococcus luteus to homogeneity. The protein is a single polypeptide with a molecular weight of 120,000. It catalyzes the removal of superhelical turns from a highly negatively twisted DNA efficiently. The reaction requires Mg2+. In a medium containing 0.1 M K+, the enzyme acts in distribut...

Ticks are key vectors of some important diseases of humans and animals. Although they 21 are carriers of disease agents, the viability and development of ticks are not harmed by the infectious 22 agents due to their innate immunity. Antimicrobial peptides directly protect hosts against 23 pathogenic agents such as viruses, bacteria, and parasites. Among the identified and characterized 24 antim...

BACKGROUND AND AIMS Adaptation to different pollinators is thought to drive divergence in flower colour and morphology, and may lead to interspecific reproductive isolation. Floral diversity was tested for association with divergent pollinator preferences in a group of four closely related wildflower species: the yellow-flowered Mimulus luteus var. luteus and the red-pigmented M. l. variegatus,...
