The ascomycete fungus Neurospora is present in many parts of the world, in particular in tropical and subtropical areas, where it is found growing on recently burned vegetation. We have sampled the Neurospora population across Spain. The sampling sites were located in the region of Galicia (northwestern corner of the Iberian peninsula), the province of Cáceres, the city of Seville, and the two ...

In a previous report, synthetic and natural biotin were stated to have identical growth-promoting properties for Lactobacillus arabinosus 17-5 (1). This paper gives a more detailed comparison of these substances in the growth of four other biotin-requiring microorganisms. The activities of synthetic dland I-biotin, dl-allobiotin, dl-diamino acid sulfate, desthiobiotin,’ and the probable biologi...

We characterized an unusual tRNA-like sequence that had been found inserted in suppressive variants of the mitochondrial retroplasmid of Neurospora intermedia strain Varkud. We previously identified two forms of the tRNA-like sequence, one of 64 nt (TRL-64) and the other of 78 nt (TRL-78) containing a 14-nt internal insertion in the anticodon stem at a position expected for a nuclear tRNA intro...

This study aims to analyze the effect of feed based on coconut husk waste fermented Neurospora sitophila growth red tilapia, and determine optimal dose waste. research was carried out in May – June 2021, at Aquaculture Laboratory Building IV, Faculty Fisheries Marine Sciences, Padjadjaran University Bandung, West Java45363 Indonesia. used a completely randomized design with four treatments repl...

Spore killer strains, found in Neurospora, provided the first recognized example of meiotic drive in fungi. In the present study, natural populations throughout the world were examined for the presence of killer strains and strains that are resistant to killing. In N. intermedia, Sk-2 and Sk-3 are present but are rare. Killer strains were found at only five sites, in Borneo, Java, and Papua New...
