Brachionus plicatilis (Rotifer) in farklı besin ortamlarında büyümesi

Farklı besin diyetlerinin rotifer (Brachionus plicatilis) kültürlerinin büyümesi üzerindeki etkilerinin araştırıldığı bu çalışmada, rotiferier Nannochloropsis sp., ekmek mayası {Saccharomyces cerevisiae) ve kurutulmuş Spirulina tozu ile beslendi. İlk denemede, optimum Spirulina konsantrasyonu günde 0.01 g /106 rotifer olarak bulundu. Deneme gruplarında alg, alg+maya, ag+Spirulina, maya+Spirulina ve maya/2+Sp/m//na olmak üzere 5 deneme grubu oluşturuldu. Mikroskobik gözlemlerde, Spirulina partikülleri havanda ezilmiş olmasına rağmen rotiferier tarafından tüketilemeyecek boyutta idi. Sonuç olarak, alg içeren grupların en iyi büyümeyi gösterdiği tespit edildi. Spirulina ise partikül büyüklüğünden dolayı rotiferier tarafından alınamadı. Maya hücreleri ise rotifer hücreleri için optimum büyüklükte olmasına rağmen, ortam kirliliğine neden olması bakımından alg ile beslenen gruplara göre daha düşük bir büyüme gösterdi.

Growth of Brachionus plicatilis (Rotifer) on various diets

Growth of Brachionus plicatilis (Rotifer) on various diets. In this study, in which the effects of various food sources on the rotifer Brachionus plicatilis were examined, rotifers were fed with Nannochloropsis sp., yeast (Saccharomyces cerevisiae) and dried Spirulina meal. In the first trial, optimum Spirulina concentration was found to be 0.01 g /106 rotifers per day. In the experimental groups, 5 groups were arranged, e.g., alga, alga+yeast, alga+Sp/Mna, yeast+Spirulina and yeast/2+Sp/ru//na. In the microscopic observations, it was seen that Spirulina particles were larger than that rotifer can consume. Consequently, the groups that contained alga showed the best growth pattern. Spirulina could not be consumed due to the larger particle size. Regarding the yeast cells, although their size are in the optimum range for rotifer feeding, they exhibited a lower growth rate compared to the groups fed with alga due to the fact that the yeast caused the culture medium to deteriorate.
