Profenofos has been known for history of contamination to aquatic systems. The fate of profenofos in liquid medium is unknown due to limited number of studies performed. Very less information is available about the degradation behavior of profenofos in the liquid medium. This study is an attempt to analyze the growth and degradation kinetics of profenofos in the minimal salt medium and Hoagland’s solution using an efficient bacterial strain Acinetobacter sp.33F. Acinetobacter sp.33F has been proven to degrade profenofos in soil earlier, but its profenofos degradation kinetics has not been evaluated. Hoagland’s medium is considered for degradation studies because it is used in the hydroponics cultivation in soil-less environments. Hoagland’s solution will act as a mimic for the soil, and its effect on profenofos biodegradation will be evaluated. The study evaluated the growth and degradation kinetics of commercial and analytical grade profenofos using an efficient bacterium Acinetobacter sp.33F. The kinetics studies were performed in minimal salt medium and Hoagland’s medium. Growth kinetics parameters including ${\mu }_{\max }$ (h⁻¹), K${}_{\mathrm{s}}$ (mg/L), K${}_{\mathrm{i}}$ (mg/L), and ${\mu }_{\max }$/K${}_{\mathrm{s}}$. were calculated. Degradation kinetics parameters including q${}_{\max }$ (mg h${}^{-1}$) and K${}_{\mathrm{S}}$ (mg/L) were calculated.

Profenofos因对水生系统的污染历史而闻名。由于进行的研究数量有限，因此丙泊酚在液体培养基中的命运是未知的。关于Profenofos在液体介质中的降解行为的信息很少。这项研究是试图分析使用高效细菌菌株不动杆菌sp.33F在基本盐培养基和Hoagland溶液中对Profenofos的生长和降解动力学。不动杆菌事实证明，sp.33F可以较早地降解土壤中的Profenofos，但尚未评估其Profenofos降解动力学。考虑将Hoagland培养基用于降解研究，因为该培养基用于无土环境中的水培栽培。Hoagland的溶液将模拟土壤，并评估其对Profenofos生物降解的影响。该研究使用高效细菌不动杆菌sp.33F评估了商业级和分析级丙诺磷的生长和降解动力学。动力学研究是在最小盐培养基和Hoagland培养基中进行的。生长动力学参数包括${\mu }_{\mathrm{最高}}$（h ^-1），K${}_{\mathrm{s}}$ （毫克/升），K${}_{\mathrm{一世}}$ （mg / L），和 ${\mu }_{\mathrm{最高}}$/千${}_{\mathrm{s}}$。被计算。降解动力学参数包括q${}_{\mathrm{最高}}$ （毫克h${}^{-\mathrm{1个}}$）和K${}_{\mathrm{小号}}$ （mg / L）进行计算。
