Growth medium recycling in Nannochloropsis sp. mass cultivation.
During cell division Nannochloropsis releases the thick and multilayered parent cell wall [Phycologia 35 (1996) 253]. The excretion of autoinhibitory substances in Nannochloropsis cultures has beenExpand

Resting cysts: A survival strategy in Protozoa Ciliophora
Abstract Encystment is a reversible cell differentiation process that also requires an antagonistic process, i.e. excystment. Both processes are genetically encoded. Encystment is of commonExpand

Preconjugant cell-cell interaction in the ciliate Euplotes crassus: a possible role of the ciliary ampules
Euplotes crassus, like other species of Euplotes, possesses organelles commonly known as ampules, which are associated with the roots of cilia and organelles composed of cilia. Ampules of E. crassusExpand

The cyst of Oxytricha bifaria (Ciliata: Hypotrichida). I: Morphology and significance
Before actual encystment, the volume of Oxytricha bifaria falls to about 20% of normal (47,700 im3 vs. 234,000 ,m3). Once it has attained this minimal volume, the rounded cell first produces a jellyExpand

Adenylate cyclase and cyclic AMP in the ciliate Euplotes crassus: involvement in both cell cycle and sexual reproduction
In this paper the presence and the possible activity of adenylate cyclase-cyclic AMP (AC-cAMP) system has been investigated through cell cycle and sexual reproduction of the ciliate Euplotes crassus.Expand
