Abstract	Mikroalge zbog brze reprodukcije i visokog sadržaja ulja ističu se kao sirovina budućnosti u proizvodnji biogoriva. Donedavno su predstavljale ključne čimbenike u mrjestilištima riba i školjkaša, ali u posljednjih dvadeset godine sve su značajnija sirovina u prehrambenoj i farmaceutskoj industriji te industriji biogoriva. Na rast mikroalgi utječu brojni čimbenici kvalitete uzgojne sredine. Razumijevanje tih čimbenika od ključne je važnosti za optimizaciju njihovog uzgoja i održivu proizvodnju. U ovom je radu istraživan utjecaj saliniteta i dužine svjetlosnog dana na brzinu rasta čiste kulture mikroalge Isochrysis galbana. Pokus je proveden u dva ponavljanja te u dvije faze. U prvoj fazi je ispitan utjecaj različiti saliniteta (15, 25 i 35 ppt) dok su ostali uvjeti uzgoja bili konstantni. U drugoj je fazi ispitan utjecaj različitih duljina svjetlosnog dana (16, 18 i 24 sata). Rezultati su za obje faze uspoređeni ANOVA testom. Najbolji rast postignut je pri salinitetu od 25 ppt te pri konstantnom osvjetljenju, odnosno duljini svjetlosnog dana od 24 sata.
Abstract (english)	Microalgae, due to their rapid reproduction and high oil content, stand out as a future raw material in the production of biofuels. Until recently, they played a key role in fish and shellfish hatcheries, but in the last two decades, they have become increasingly important as a raw material in the food, pharmaceutical, and biofuel industries. The growth of microalgae is influenced by various factors in the cultivation environment. Understanding these factors is of crucial importance for optimizing their cultivation and ensuring sustainable production. This study investigates the impact of salinity and photoperiod on the growth rate of a pure culture of the microalgae Isochrysis galbana. The experiment was conducted in duplication and in two phases. The first phase examined the influence of different salinities (15, 25, and 35 ppt) while keeping other cultivation conditions constant. In the second phase, the impact of different photoperiods (16, 18, and 24 hours) was investigated. The results for both phases were compared using ANOVA testing. The best growth was achieved at a salinity of 25 ppt and under constant illumination, corresponding to a photoperiod of 24 hours.
